 in the QoS provisioning in Fast/Gigabit Ethernet, the Q-CNM nodes in the source and destination intranets receive the QoS-connectivity requests from the Q-SIP proxy server, and check the available network resources as CAC operations. If the new QoS flow is accepted, the Q-CNM controls the configuration of © 2009 by Taylor & Francis Group, LLC SIP Handbook: Services, Technologies, and Security the QoS scheduling on appropriate AC in the IEEE 802.11e WLAN AP. The actual QoS-connectivity establishment is requested by the QSTA via IEEE 802.11e MAC protocol with TSPEC parameters. The Q-CNM can manage the overall aggregated throughput of each AC in the intranet by adjusting the beacon interval, and the proportion of contention-free periods (CFPs) and contention periods (CPs). 15.3.5 QoS-Aware CNM (Q-CNM) In order to support QoS-aware service provisioning in a Fast/Gigabit Ether- net and IEEE 802.11 WLAN environment, the QoS-aware customer network management (Q-CNM) system should provide QoS-aware resource allocation with CAC function. In this study, we designed and implemented Web-based Enterprise Management (WBEM)-based Q-CNM [4]. The Q-CNM provides QoS-aware resource allocation and CAC in the intranet, configures the details of the per-port queue management and scheduling of the Fast/Gigabit Eth- ernet switch. It also configures the policy-based operational parameters in IEEE 802.11e WLAN. The Q-CNM maintains the detailed operation status of each QoS-aware Basic Service Set (QBSS) in the IEEE 802.11e WLAN and Fast/Gigabit Ethernet subnetwork. For the QoS-guaranteed multimedia service provisioning on IEEE 802.11e- based intranet, we developed a Q-CNM as shown in Figure 15.7 [4].
