 management module maintains a record of users' average resource usage for subscribed services and the service type, for example, unicast or multicast, requested by the users in the EPON network. In the experiment, the traffic admission decision made in resource management module is applied to EPON OLT to schedule the downlink packet transmission. After the requested service is granted, the resource management module sends con- trol message to EPON controller to inform the user's traffic type and priority. In the OLT traffic controller design, the subscribed multicast packets are put in one logi- cal queue in OLT to avoid duplicate packet delivery, unicast packets are put into different unicast queues based on their service priorities. Packets in different queues have different priorities to be transmitted. Traffic of subscribed services has higher priority than that of unsubscribed services, which is transmitted in a best-effort manner. The resource allocation scheme controls the downlink bandwidth resource allocation and provides a fair EPON resource usage among the users in the case of users competing for the resource, and is able to differentiate user's service priority and charge users for different service and resource usage accordingly. 9.3.3 Multimedia Services over Wireless Mobile Network This experiment illustrates the use of smart-phone to initiate and orchestrate the playback of online video program on-the-go, and to a display device of choice. Using the IMS-based mobile service platform, an Android phone authenticates and interacts with the IMS core network to subscribe a video channel from the program listing. The orchestrated service shows selected videos streamed to a remote client for display via quality-of-service-guaranteed connections established via an IMS- based optical network service plane. Figure 9.5 shows the steps and signaling sequence for the wireless mobile experiment. The detail steps are as follows: Step 1: The Android phone sends a SIP REGISTER message to the IMS Core to register
