C 2009 by Taylor & Francis Group, LLC Q-SIP/SDP for Converged Heterogeneous Wired and Wireless Networks 363 with Network Management Systems (NMSs) in other domains. Q-CNM con- figures the intranet with Fast/Gigabit Ethernet and IEEE 802.11e WLAN. Since Fast/Gigabit Ethernet switch and IEEE 802.11e WLAN AP do not provide any network layer signaling, the Q-CNM handles the resource man- agement and resource allocation. Through the Fast/Gigabit Ethernet com- mand line interface (CLI) provider and IEEE 802.11e provider, the Q-CNM configures the details of QoS provisioning in Fast/Gigabit Ethernet and IEEE 802.11e WLAN. The Q-CNM has the detailed information of each QSTA in the intranet, including the location and current attached QBSS, the availability of IEEE 802.11e functions. Q-CNM also maintains the aggregated allocated bandwidth at each QBSS and at each port of the Fast/Gigabit Ethernet switch node. Experimental Implementations and Performance Evaluation of QoS Provisioning in Heterogeneous Wired and Wireless Convergence Networks 15.4.1 Testbed Network of Converged Heterogeneous Wired and Wireless Networks Figure 15.8 depicts the testbed network of converged heterogeneous wired and wireless network for the performance evaluation of the overall QoS provision- ing of multimedia real-time services.
