The good news is that the Oscar shorts are short; the better news is that they're good -- except for one of the 10. Ever since the Academy has made the nominations for shorts available to the viewing public, the Oscar presentations have been fuller, more fun to anticipate.
Do not expect a knee-slapper from this comedy. Expect the pain of two people living together, told with a knowing smile and sigh. If you've been married more than 30 years, as has the couple in "Le Week-End," you might find parallels.
The good news about "Closed Circuit" is that neither its cloaks nor its daggers are cliches. The plot does not depend on justice prevailing but on reality reigning, so it is more cynical than triumphal. "Closed Circuit" is about terrorism and secrets, duplicity and circuity.
For his latest cinematic project entitled Another Year, British writer/director Mike Leigh, as usual, employed his unique working style for developing his projects. Leigh brings together his cast, has an idea he wants explored, and over several months this collaborative community arrives at the script that will become the film.

Hi all,
I want to make a filter using checkboxes that would allow users to filter articles by ticking one or multiple checkboxes, each checkbox representing a specific tag.
For Example:
<form action="<?php get_the_selected(); ?>" method="post">
<input type="checkbox" name="selections[]" value="tag1" />Select1

<input type="checkbox" name="selections[]" value="tag2" />Select2

<input type="checkbox" name="selections[]" value="tag3" />Select2

<input type="submit" name="formSubmit" value="Submit" />
This is just an example, I am using like 20 or more checkboxes..
Now when you check one or two or three chechboxes and click submit button, I want to make the function that would generate a tag link like this:
or tag1+tag2
or tag1.. depending on the selection...
I was searching the web and found something that I thought would work
But the problem is that this tutorial isn't done using wordpress.. And when I try to add function in functions.php
function get_the_selected() {
$allselected = $_POST['selections'];
echo("You didn't select anything.");
$N = count($allselected);
echo("You selected $N: ");
for($i=0; $i < $N; $i++)
echo($allselected[$i] . " ");
It's not working.. to be precise, even when I check some boxes, I still get that I didn't check any.. I know that this function probably would not achieve my desired result, but for now I would like to just make it so it could correctly detect my checked boxes...
This is the first time I am doing something like this... :)
Also, when I created checkbox-form.php file and put all the code.. it detected everything fine.. So I think that this function needs only some minor adjustments, but the lack of my skill prevents me from writing the correct function
So, could anyone help me make the correct function ? I hope you understoon what I'm after. I would really appreciate any thoughts, suggestions, ideas :)
Thank you in advance,

ComSIS Vol. 1, No. 1, February 2004 45 Offensive and Defensive Adaptation in Distributed Multimedia Systems♣ ♣ Roland Tusch1∗, László BöszörményiHermann Hellwagner1, Balázs Goldschmidt1 2, 1, Peter Schojer1 Institute of Information Technology, Klagenfurt University, Klagenfurt, Austria 2 Department of Control Engineering and Information Technology, Budapest University of Technology and Economics, Budapest, Hungary Abstract. Adaptation in multimedia systems is usually restricted to defensive, reactive media adaptation (often called stream-level adaptation). We argue that offensive, proactive, system-level adaptation deserves not less attention. If a distributed multimedia system cares for overall, end-to-end quality of service then it should provide a meaningful combination of both. We introduce an adaptive multimedia server (ADMS) and a supporting middleware which implement offensive adaptation based on a lean, flexible architecture. The measured costs and benefits of the offensive adaptation process are presented. We introduce an intelligent video proxy (QBIX), which implements defensive adaptation. The cost/benefit measurements of QBIX are presented elsewhere [1]. We show the benefits of the integration of QBIX in ADMS. Offensive adaptation is used to find an optimal, user-friendly configuration dynamically for ADMS, and defensive adaptation is added to take usage environment (network and terminal) constraints into account. Key words: stream-level adaptation, server-level adaptation, MPEG-4, MPEG-7, MPEG-21. ♣ This research project is funded in part by FWF (Fonds zur Förderung der wis-senschaftlichen Forschung), under the projects P14788 and P14789, and KWF (Kärntner Wirtschaftsförderungsfonds). ∗ Corresponding author.

46 ComSIS Vol. 1, No. 1, February 2004 1. Introduction Adaptation is - in a general sense - the capability to respond to changes of the environment by the change of some own characteristics, without losing the own identity. If a living creature feels hungry, but sufficient food is not available, then it has two choices for survival: Either it is able to enlarge the available food resources, e.g. by moving to a better place, or to change its inner need and learn to be satisfied with less or worse food. The first approach could be called offensive, the second defensive adaptation. Obviously both have their limits and have a common prerequisite: flexibility. (Our creature has to be flexible either to go outside and find new places or to go inside and be satisfied with less food - or to do both, if e.g. a new place can be found, which is, however, still not sufficiently rich of food.) Offensive adaptation is usually proactive (it is better to start to look for an opulent place before getting too hungry), whereas defensive adaptation is usually reactive (if there is no food, there is no other choice than getting humble). In distributed multimedia systems - especially in video management systems - adaptation is becoming increasingly important. The reason is simple: due to the challenging amount of data involved and the soft real-time constraints, video management systems are always "resource hungry". This hunger can be satisfied neither by best-effort resource management, which cannot handle timing constraints, nor by reservation, which over-allocates resources (for the worst case). Therefore, on the long term, adaptation is a necessity. It is - fortunately - also an opportunity, both in its defensive and in its offensive forms. To find new places and new food, we have to be able to communicate with the environment, we must understand its signals. In a computerized world this means: being able to support standardized communication. Fairly much research has been done on media adaptation, which is obviously defensive [2–5]. The required flexibility lies in the inner structure of the media data. Especially by sophisticated video coding techniques, ample space is created for transcoding of video data resulting in smaller size and bitrate and in still acceptable perceptual quality. Fortunately, the relation between size and quality reduction is usually non-linear: up to a certain limit, large size reduction causes a moderate quality loss. Much less research has been done on offensive (also called server-level) adaptation. The reason for this reduced interest lies probably in the fact that most distributed multimedia systems lack the necessary flexibility. Such a system must be able to dynamically acquire new resources and move/replicate its own code and data as needed. This requires flexibility of the architecture and consequent adherence to standards – both rare characteristics in current distributed multimedia systems. In the course of the ADMITS (Adaptation in Distributed Multimedia IT Systems) project [6,7] we address both kinds of adaptation and their integration as well. Offensive adaptation is realized by an Adaptive Distributed Multimedia Server (ADMS), which is able to allocate new server nodes on the network and migrate functionality and data to them on demand. ADMS has a highly flexible architecture enabling this kind of migration operations. If for example the host
Page 3
ComSIS Vol. 1, No. 1, February 2004 47 recommender component notices that a certain group of clients could be better served if the data collector component (collecting stripe units from the data storage nodes and streaming them to the clients) were physically located near to this client group, then it simply allocates a new node and sends a copy of the data collector code there. A detailed description of ADMS is given in Section 3. Defensive adaptation is realized by a Quality Based Intelligent Proxy (QBIX). The proxy is able to handle different quality levels of the same video (based on MPEG-4 [8] coding and on transcoding, supported by MPEG-7 [9] meta data). It can operate as a cache, in which case it uses adaptive cache replacement algorithms. Instead of discarding replacement candidates it reduces their quality as long as possible, thus raising the hit rate considerably. It can also operate as a gateway, in which case it serves client devices with different capabilities by videos of different quality. It can e.g. send a high quality version of a video to clients on a personal computer and a low quality version to clients with a PDA. A detailed description of QBIX is given in Section 4. An integration of the offensive and defensive adaptation is given if we use the intelligent proxy itself as a component of the adaptive server. Due to the flexible architecture this is technically easy. The usual strategy is that we first try to apply offensive adaptation by enlarging the server by new nodes to host the proxy functionality. As the proxy is able to perform defensive adaptation, it still can reduce the quality of the stored videos if necessary. Whereas ADMS and QBIX are already fully operational, the integration is still in progress. The quantitative evaluation of the effect of the integration is the next step in the ADMITS project. 2. Related Work In [10] it is shown that distributed multimedia servers have benefits over single server architectures regarding scalability and server-level fault tolerance. We discussed in earlier papers [11,12] that existing distributed server architectures like the Berkeley Distributed VoD System [13], the Tiger Video Fileserver [14], or the EURECOM VoD Server [15] have a monolithic architecture and are performance-optimized to one main goal: serving thousands of simultaneous client requests. However, in heterogeneous environments, it is usually not the server, but the network that becomes a bottleneck. This is especially the case if a certain level of quality of service is to be guaranteed in terms of latency times, bandwidth availability or packet loss. Although sophisticated commercial systems like the Darwin Streaming Server (DSS) – an open source version of Apple's modular QuickTime Streaming Server – or the Helix Universal Server (HUS) [16,17] – developed by RealNetworks –, show a highly distributed architecture, their organization is static, they cannot acquire new resources on the network on demand. Content distribution networks (CDNs) are dedicated collections of servers (called data centers) strategically located across the Internet. A typical
Page 4
48 ComSIS Vol. 1, No. 1, February 2004 example for a CDN is Akamai's distributed content delivery system, which deploys more than 12000 servers in over 1000 networks around our planet [18]. Based on the assumption that the strategic locations of the data centers are well chosen, a CDN is definitively a good solution for adapting the physical location of a media stream. It is highly available and serves the streams from locations where clients perceive a good quality of service. However, the strategic positioning of data centers and edge servers is typically done manually by observing client demands. A CDN does not provide means for performing strategic placements automatically. In a peer-to-peer (P2P) file sharing network, peers collaborate to form a distributed system for the purpose of exchanging content [19]. However, the applicability of P2P networks for adapting the location of media streams in a distributed streaming environment is rather poor. In particular, it faces the following two problems: (i) Participation in a P2P network is purely voluntary. A recent study has shown that most peers are run by end users, who suffer from low availability, and have network connections with a relatively low capacity [20]. (ii) It is server-less, which makes a controlled distribution of content very difficult [21]. Nevertheless, there are approaches that use P2P content delivery for media streaming, as e.g. presented in [21] and [22]. An offensive server architecture requires a QoS-aware middleware providing active support for adaptation steps. Extensive work has been done in the area of QoS-aware middleware for ATM-based networks and also for systems using RSVP [23–25]. These systems are hardly appropriate for the Internet, where resource reservation is still rather theory than practice. On the other hand, considerable work has been done on end-to-end distance monitoring and estimation in the Internet [26–29]. measurement/estimation algorithms can be used to approximate QoS awareness for a middleware as needed for offensive adaptation. Although certain middleware systems support dynamic replication or migration of services and components, like Jini [30] or Symphony [31], they do not provide measurements and estimations of network distances and server resources. One possibility to cope with typical Internet problems such as network jitter and bandwidth limitations is media adaptation. QBIX [1] is a quality based intelligent proxy that caches whole videos and offers media adaptation support to reduce the size/bandwidth requirements of the cached videos. Related work in this area is sparse. Examples are periodic caching of layered coded videos [32], combination of replacement strategies and layered coded videos [33], quality adjusted caching of GoPs (group of pictures) [34], adaptive caching of layered coded videos in combination with congestion control [35] or simple replacement strategies (patterns) for videos consisting of different quality steps [36]. Most of these proposals rely on simulation to evaluate the performance of the caching techniques. Therefore some assumptions have to be made about the structure of the videos (e.g. layered videos). Because QBIX supports re-encoding of videos without layered encoding, a real implementation was used to evaluate the impact of re-encoding on the quality of cache replacement, something which is hard to simulate. The only other project we know about, also offering a real implementation is described in Such bandwidth and delay
Page 5
ComSIS Vol. 1, No. 1, February 2004 49 [35]. This work relies on proprietary systems and protocols, whereas QBIX integrates modern multimedia standards like MPEG-4 [8], MPEG-7 [9], the upcoming MPEG-21 standard [37] and communication standards like RTP and RTSP [38]. Integrating QBIX into ADMS will create the very first distributed multimedia server that combines offensive and defensive adaptation. 3. QoS-driven Server-level Adaptation In a statically configured distributed server architecture with a behavior steered by several sorts of distance metrics to the clients (e.g. by evaluating RTCP statistics of former clients), client requests can either be accepted or denied (admission control). There is no third option. In cases of increased denials due to network resource shortages, such a server has no chance to adapt its layout to serve more clients. Defensive media adaptation (see more in Section 4) cannot always cope with such situations either, because (1) adaptation of the media content is not always possible and (2) it may even be prohibited by the content provider. In the sequel, we therefore introduce an adaptive distributed server architecture that can modify its configuration according to client requests. We discuss this architecture and evaluate its performance behavior. 3.1. Components of a Distributed Multimedia Streaming Server 3.1.1. Guidelines for Component Identification In [11,12] we describe the architecture of an adaptive distributed multimedia streaming server (ADMS), which explicitly controls its own layout. There is a trade-off between the grade of flexibility and the complexity caused by too large a number of components. We identified four basic components that are necessary and sufficient for the composition of a dynamically reconfigurable streaming server. Figure 1 illustrates a sample combination of these components, including the standard protocols used.
Page 6
50 ComSIS Vol. 1, No. 1, February 2004 Fig. 1. Components and Protocols Used in a Component-based Streaming Server Environment The following two guidelines have to be taken into account when designing a component-based distributed streaming server. First, each component must be independent, reusable, adaptable, and combinable as much as possible. These considerations are valid for a static distributed environment as well. For a dynamically adaptable system the components must additionally be movable. Second, in order to get a lean structure with a strongly limited number of components, each component should fulfill one substantial logical task. Such substantial tasks are data acquisition, data streaming, data storage management and overall control. For example, during a data acquisition scenario initiated by a production client, a media stream has to be distributed ("striped") among a set of server nodes. One single component is needed to receive the stream data, to split the stream into smaller pieces, and to distribute the pieces among a set of data nodes. The data nodes themselves are equipped with a component for storing and retrieving pieces of media data. Thus, a distribution component can be combined with a number of storage components, which all may run on separate server nodes. Following these guidelines, four basic components have been identified to constitute a component-based distributed streaming server: data managers (DMs), data distributors (DDs), data collectors (DCs), and cluster managers (CMs). The implementation of the components can use different technologies, interoperability is achieved by using CORBA as communication medium [39]. 3.1.2. Data Manager Data managers are the key components in the ADMS architecture. A data manager provides means for efficient storage and retrieval of elementary streams or segments thereof. Since one elementary stream or segment may be striped among a number of data managers, each data manager only stores a
Page 7
ComSIS Vol. 1, No. 1, February 2004 51 portion of the stream or segment. Figure 2 illustrates the internal storage organization of the media streams. The data manager stores a set of partial media streams, which themselves consist of a set of leaf and compound media segments. Real media data is only stored in leaf media segments. Compound segments are used to describe syntactic and semantic relations among elementary segments. Fig. 2. Objects Comprising a Data Manager Component 3.1.3. Data Distributor A data distributor component is responsible for the distribution of media data received from a production client or a live camera to a selected set of data managers. The unit of distribution is a so-called stripe unit, which can be either of constant data length (CDL), or of constant time length (CTL). In CDL mode, parity units are generated in order to cope with data manager failures. The number and location of target data managers and the mode of striping (single, narrow or wide) is advised by the cluster manager component. In cases of a non-live source, the process of distribution can be driven by MPEG-7 [9] metadata which describe the temporal decomposition of the media stream. A media stream can be decomposed into a number of segments, organized in an arbitrary number of levels. Figure 3 presents a sample temporal decomposition of a video stream into two segments, using an MPEG-7 descriptor. The data distributor distributes only elementary streams, since the target system is designed for streaming scenarios based on RTP. Thus, if the media source contains a multiplexed stream, it has to be demultiplexed into elemen-tary streams before striping.

52 ComSIS Vol. 1, No. 1, February 2004 Fig. 3. Temporal Decomposition of a Video Stream using MPEG-7 3.1.4. Data Collector The data collector performs the inverse operation of data distribution. It collects stripe units of a certain media stream from the appropriate set of data managers, re-sequences the units and sends the buffered stream to the client via an RTP connection. It provides server-level fault tolerance by exploiting parity units in case of unavailable data managers. The collector may also incorporate a caching component, thus reducing client startup latencies and bandwidth consumption. In particular, the data collector can play the role of a proxy server, which is dynamically assigned to serve a group of clients by the cluster manager. This constitutes the difference to usual proxies, which are selected by the clients themselves. An interesting approach is the integration of gateway functionalities into the data collector. A gateway performs transcoding in order to adapt to given network or client device constraints. It may e.g. reduce the resolution of a video which is sent to a client equipped with a small-resolution screen. A data collector incorporating gateway functionality is a particularly appealing example for the combination of offensive and defensive adaptation. We use offensive adaptation to bring the gateway to the proper place, and there use defensive adaptation to comply with the given client capabilities.
Page 9
ComSIS Vol. 1, No. 1, February 2004 53 3.1.5. Cluster Manager A cluster manager is the initial entry point for clients. In contrast to the three component types described before, there is (usually) only one instance of it in an ADMS cluster. It dynamically manages the locations of the other three component instances and maintains knowledge about the distribution of elementary streams among data managers. An important point is that the cluster manager does not serve client requests by itself. Instead, it redirects a request to an appropriate data collector or distributor, respectively. The most appropriate node to host a data collector or distributor is found by the so-called adaptation engine (abbreviated as AE in Figure 1), which is a sub-component of the cluster manager. In a static distributed multimedia server (SDMS) system the adaptation engine may perform several selection algorithms for finding the most appropriate candidate among the given set of nodes. However, if no appropriate candidate can be found, the request has to be denied. In contrast, in an ADMS environment, the adaptation engine may transmit (replicate or migrate) a data collector or distributor instance to an idle server node candidate, thus satisfying requests which might have been denied by a static architecture. 3.1.6. Protocols for Component and Client Interaction As demonstrated in Figure 1, the only control protocol used between clients and DMS components is the RTSP [38] protocol. Keeping the client implementation CORBA-unaware has the benefit that it may interact with any streaming server which conforms to media streaming standards. The control protocols used internally between DMS components are CORBA-based and conform to the IDL specifications of the components. The "master mind" behind all kind of scenarios is an MPEG-7 meta database, which stores syntactic and semantic information about the media streams stored on the server. 3.2. ADMS: An Adaptive Distributed Multimedia Streaming Server The components introduced in Section 3 could be parts of either a static or a dynamic distributed multimedia streaming server (SDMS resp. ADMS). Before introducing the middleware, which is the engine making the server dynamic (see Section 3.2.2), we discuss the main shortcomings of a static architecture. 3.2.1. Discussion of the Static Architecture In [10] it is claimed that distributed video servers are load balanced regardless of the skew in video popularities. This is only valid for an architecture where the data collectors are integrated into the client application
Page 10
54 ComSIS Vol. 1, No. 1, February 2004 (proxy-at-client model). Consider that there are M data manager and N data collector instances in an SDMS, supporting the proxy-at-server or the independent-proxy model. Each server node has the same capacity C, and each client request demands the same amount of resources c on a data collector (Figure 4). Fig. 4. Host Resource Saturation Progression in an SDMS In a fair resource reservation scheme with a uniform distribution of requests to the data collectors, N data collectors can admit at most ⎥⎦⎥⎢⎣⎢⋅cCN simultaneous requests. On the other hand, a requested media object is striped among the M data managers, resulting in a capacity demand of Mc on each data manager on average. Thus, the total number of client requests that can be admitted on one data manager node is bound by ⎥⎦⎥⎢⎣⎢⋅cMC. Since in a typical static server configuration M is a multiple of N, overall load-balancing is not given anymore. Figure 4 illustrates this imbalance showing that although the M=10 data manager nodes are still under-utilized at 20%, the N=2 data collectors are reaching their saturation point. The assumed resource demand ratio is δ = 0.1 per request on a data collector. To get rid of the shortcomings of the SDMS architecture, an infrastructure is required which allows for a dynamic composition of the components described in section 3.1, resulting in an adaptive distributed multimedia streaming server (ADMS). Components should be replicable and/or migratable on demand, allowing the dynamic composition of a virtual server [31]. We developed a CORBA-based infrastructure called Vagabond2 [40], which supports dynamic instantiation, migration, replication and evacuation of so-called adaptive applications (a synonym for component in Vagabond2).
Page 11
ComSIS Vol. 1, No. 1, February 2004 55 3.2.2. Vagabond2: A Middleware for Virtual Servers in Internet Settings Vagabond2 is a CORBA-based middleware, implemented in Java, consisting of two general modules: a module for component management, and a module for component adaptation (see Figure 5). The component management module provides two services for a distributed server like ADMS: an application service for component movement between Vagabond2 hosts, and a host service for registering and querying harbours. A harbour represents the runtime environment which must be running on each Vagabond2 host. Vagabond2 enables loading the Java byte code of an adaptive application, and instantiating this as a CORBA servant. The component adaptation module provides two central services for offensive server adaptation: the adaptation service and the resource broker. Fig. 5. Modules of the Vagabond2 Middleware The adaptation service provides the so-called host recommender, which tries to find an optimally located host for a certain component under a given set of constraints. An example for a set of QoS constraints described by an MPEG-21 descriptor embedded in an RTSP SETUP message is given in Figure 6. The MPEG-21 [37] network characteristics descriptor is rooted by the DIA (Digital Item Adaptation) element. The capability element of the descriptor says that a bandwidth range between 32 and 128 kbit/sec is acceptable, packets might be delivered out of order and may be lost. The condition element specifies that the 128 kbit/sec link may be fully utilized, but on average should only get 64 kbit/sec. The packet delay from a data collector to the client should not be greater than 500 msec, and delay variation not greater than 100 msec. Finally, the packet loss rate must be below two percent.
Page 12
56 ComSIS Vol. 1, No. 1, February 2004 Fig. 6. RTSP SETUP Message Including an MPEG-21 DIA Descriptor The RTSP message further indicates (field Range) that the client wants to get the stream segment from the 20th to the 40th second (media relative time). Additionally, the request should be scheduled for March 1st, 2003, at 14 o'clock. This time indication at session setup enables the adaptation engine to proactively schedule the request to an appropriate data collector, taking into account the given QoS constraints, and the location of the data managers, where the stream data has to be retrieved from. When a new client request R arrives, the host recommender has to work out which host should run the data collector instance servicing R, and whether it should be an existing or a new (replicated or migrated) instance. The host recommender has to solve the dynamic server selection problem to find the best available data collector. If no appropriate data collector exists at all, an SDMS has to reject the request. In contrary, the ADMS may have enough time to create a new place by solving the capacitated facility location problem [41]. In order to prepare these decisions, the host recommender cooperates with the resource broker - the second service of the adaptation module. The broker provides means to admit immediate and future QoS-constrained requests, and to perform logical reservations of network and host resources. It achieves this by using two additional services: the network resource service, and the host resource services, the latter running on each Vagabond2 harbour. An excerpt of the network resource service's IDL specification is shown in Figure 7. Via the NetworkInfo interface we can get for example the capacity of a route between two arbitrarily connected Vagabond2 server hosts. Supported distance metrics are bandwidth, delay, packet loss rate, and round trip time. In this context, the specification of a period is important. If the period covers future time points, the service provides an estimated value, by applying time series analysis based on measurements. The network resource service requires that on each Vagabond2 harbour a network monitor is running, which periodically
Page 13
ComSIS Vol. 1, No. 1, February 2004 57 measures instantaneous values of all supported metrics. For the host resource service a similar scenario is applied: available host resources (CPU, memory, and disk space) are periodically measured and their throughputs are benchmarked on harbour start-up. Fig. 7. Vagabond2's Network Resource Service Specification There is an important difference between finding optimally placed nodes for ADMS data collectors and Web server replicas as described in [42], namely the asymmetric character of the recommendation problem. In ADMS, the connections between data managers and data collectors are different from those between collectors and clients. In the former, data transmission must be error-free and is fairly irresistible against jitter, therefore TCP connections can be used. In the latter, videos must be streamed with limited jitter, but not necessarily error-free (e.g. B frames might be lost), therefore RTP/UDP based communication can be used. A simulation experiment has shown that when many data collectors are near to the client (i.e. low UDP and large TCP communication), the standard deviation (the jitter) remains low, but the total amount of data travelling in the network increases (see Figure 8). 3.2.3. Making an ADMS Component 'Movable' An adaptive component must be derived from the CORBA interface AdaptiveApplication [40, 12]. The key functionality of this interface is the getApplicationInfo() method, which is used by a harbour to request for the binaries of the component, and optionally for a set of files it may depend on. Figure 9 illustrates this as an excerpt of Vagabond2's IDL specification.

Vagabond2's Core Interfaces for Adaptive Components Figure 10 illustrates how a data manager component is derived from the AdaptiveApplication interface. First, a common abstraction layer is introduced, which is valid for all four ADMS component types. It introduces the interfaces ADMSServerApplication and Session, allowing the establishment of rate-controlled and transaction-based sessions of certain types (retrieval, acquisition, or management). Second, the bottom layer defines the interfaces and structures comprising the ADMSDataManager is used to create so-called data manager sessions (DMSession). Each session is associated with exactly one elementary stream. A data manager session provides means to store stripe units for a certain stream segment, to compose a segment tree of known segments, or to retrieve stripe units of a certain segment via a stripe unit iterator. Based on the session's admitted data rate (in kbit/sec), the unit iterator allows to retrieve an according number of stripe units per second. data manager component. An
Page 15
ComSIS Vol. 1, No. 1, February 2004 59 If an ADMS component is implemented in another language than Java, a Java wrapper component must be added. The binary code has to be carried in the dependent files archive as a shared library. Since an ADMS environment may consist of heterogeneous nodes, the host service provides information about the operating system on a certain harbour, in order to move suitable code to it. Fig. 10. Data Manager Component as Special Adaptive Application of Vagabond2 3.2.4. Discussion of the Adaptive Architecture We have evaluated a prototype implementation of our component-based offensive server in the ADMS test bed illustrated in Figure 11. We measured the effect of replicating data managers between two LANs connected via the Internet. One of the LANs was located in Budapest (B-LAN), the other one (I-LAN) in Klagenfurt. The geographical distance of about 500 km assured a "real" Internet setting. The retrieval client was located in the I-LAN and ran a data collector instance on its own host. Each performance test consists of five test runs and is repeated 50 times. In each run, a sample media stream of 12.5MB size is retrieved from the data manager instances. In test run 0, all data manager instances are running in the remote B-LAN. In test run 1, the data manager from host 8 is replicated to host 4, meaning that one data manager moves "closer" to the data collector. Both the component code and the requested media stream are replicated, since hosts 1 – 4 are initially

While at home for a change here in Southern Maine, I decided to keep the WorthPoint show presence going strong with a visit to the 34th annual Ogunquit antiques show at the Dunaway center in Ogunquit, Maine that was held September 13-14. I am so glad that I made an appearance at this small show. I saw very high end quality merchandise, in a small selected dealer setting. I attend shows all over the
place and this show had a great ambiance and quality antiques to match the atmosphere. The show was 25 or so dealers, mostly from the immediate area, all seemed more than happy to be there, and furthermore were very willing to share stories about their antiques and experiences.
As a year round resident of Southern Maine, I really appreciate all the collectibles that are here in my backyard, Maine is very rich in this market. I saw some really impressive Roseville pottery pieces, some wonderful depression glass, 2 beautiful works by New Hampshire native Maxfield Parrish, and countless other treasures.
In my show travels, I was very pleased to see the likes of Ed McDonough Jr. Ed is a Worthologist for WorthPoint and was selling some of his quality jewelry and related wares at the show. Ed and his dad, Ed Sr. are also locals from Saco, and operate Seven Gables. You may have seen them answer coin & jewelry questions on the site as this is their area of expertise. I always love running into fellow site users and employees while I am in the field.
I would rate the show an overall success, as all the proceeds benefit the Ogunquit Heritage Museum, which is an experience in itself. Ogunquit has always been known as a beach front tourist community with a major flare for the arts. Countless celebrities have stomped there, whether on vacation or doing an off broadway show at the world famous Ogunquit Playhouse.
If you vacation in the Ogunquit area, please check and see what antiques festivals are in the area at the time. If there are no shows, you can shop the antiques co-op malls that line the entire seacoast in this collectibles rich area. Please check out the pictures that I was able to get from this quality show, I think you will be as impressed as I was at the quality merchandise displayed.
See you at the next show!!!!
