such as IEEE 802.3 Fast/Gigabit Ethernet or IEEE 802.11 wireless LAN, however, there is no explicit connection establishment. Instead, we must provide the bandwidth allocation by configuration of Fast/Gigabit Ethernet Switch ports with proper CAC function for the guaranteed QoS provisioning. The end- to-end connection establishment or resource reservation in network on such heterogeneous networking environment, should be tightly cooperated with the session layer signaling (e.g., SIP/SDP). In this chapter, we propose a session and connection management architec- ture for the QoS-guaranteed real-time multimedia service provisioning on converged heterogeneous wired and wireless network, with Q-SIP/SDP, RSVP-TE and CAC functions. The detailed interaction scenario and related algorithms for QoS-guaranteed real-time multimedia session, resource reser- vation, and connection establishment are proposed. From the experimental © 2009 by Taylor & Francis Group, LLC Q-SIP/SDP for Converged Heterogeneous Wired and Wireless Networks 349 implementation of the proposed scheme on a small-scale converged hetero- geneous wired and wireless network testbed, we verified that the proposed architecture is feasible for the QoS-guaranteed real-time multimedia service provisioning. We analyze the network performance and end-to-end QoS per- formance parameters. The rest of this chapter is organized as follows. Section 15.2 briefly explains the related work, including heterogeneous networking technologies in broad- band convergence network (BcN), SIP/SDP, and RSVP-TE. Section 15.3 explains the functional model of the proposed session- and network-layer sig- naling with related resource reservation and CAC. Section 15.4 explains the performance analysis of QoS provisioning with the proposed scheme based on experiments on a testbed. Finally, Section 15.5 concludes this chapter.
