of IEEE 802.11e, we differentiated and classified the QoS-guaranteed video service, and map the QoS required multimedia services into the AC_VI in IEEE 802.11e EDCA mechanism by using Type of Service (ToS) field in the IP header. The other best effort traffic is processed as AC_BE in IEEE 802.11e EDCA. The QoS-aware traffic and background traffic are generated in the same traffic pattern. The packet size is 1,400 bytes, and the packet inter-arrival time is adjusted according to the target throughput. The data rate shown in this paper is measured at IP-layer, not at physical layer. As shown in Figure 15.10, the Q-CNM configures the QoS-provisioning on IEEE 802.11e WLAN according to the request from Q-SIP/SDP proxy server [4]. Q-CNM includes the resource management of the WLAN with CAC for QoS-guaranteed services, traffic classification based on service level agree- ment (SLA), and configures the QAP to provide mapping between classified traffic and IEEE 802.11e EDCA access categories. Q-CNM also configures C 2009 by Taylor & Francis Group, LLC SIP Handbook: Services, Technologies, and Security Q-SIP/SDP Proxy server Q-CNM Traffic classification based on service level Set CoS priority Resource queue, Weighted agreement classification, management Round Robin (WRR) Mapping between for WLAN metering, scheduler and WRED classified traffic and and marking according to DSCP IEEE 802.11e AC values STA_BK STA_BE TSPEC negotiation STA_VI or AC mapping Cisco 2950 CO 1242AG Fast Ethernet switch 302.11e QAP) STA_VO IEEE 802.11g/e wireless LAN FIGURE 15.10 Configurations for QoS-guaranteed service provisioning on IEEE 802.11e Wireless LAN. the packet classification, metering, and marking at the access switch in the intranet, and sets the CoS priority queue, WRR scheduler, and WRED queue for each class type. 15.4.2.3 Connection Establishment for QoS Provisioning at IP/MPLS Backbone Network The real-time multimedia service will require guaranteed QoS provisioning and traffic parameters according to its applications [18].
