"The Real-time Channel Administration Protocol" Bruce A. Mah bmah@tenet.berkeley.edu The Tenet Group University of California at Berkeley and International Computer Science Institute The Real-time Channel Administration Protocol (RCAP) provides control and adminstration services for the Tenet Real-Time Protocol Suite, a set of connection-oriented network- and transport-layer protocols for real-time communication. RCAP performs per-channel reservation of network resources based on worst-case analysis to provide hard guarantees on delay, jitter, and packet-loss bounds. It uses a hierarchical approach to provide these guarantees across a heterogeneous internetwork environment. This talk describes some of the motivations behind RCAP, its current design, and the state of its implementation.
