Dynamic session management for static and mobile users
Yigal Bejerano, Israel Cidon, Joseph Seffi Naor · 2000
Most modern communication systems that support real-time communication (ATM, ISDN, Frame-Relay, etc.) are based on connection oriented technologies. This is also true for cellular and Personal Communication Systems, where the users are mobile. Consequently, selecting good routes for Virtual Channels (VCs) is considered as one of the most important problems in modern networks. Usually, the VC route is determined during the session initialization along the shortest path (with respect to some metric) between the users and remains the same during the entire session. However, the user mobility and the fact that the cost of a session may also depend on its duration, motivate the development of dynamic session management algorithms. Such algorithms may reroute the VCs dynamically during the sessions for improving session cost and for supporting handoff operations of mobile users.
