Mobile Real-Time Communications in FDDI Networks

摘要

We propose an architecture of FDDI-based mobile networks and address issues that arise in providing real-time communication services on such networks. A wide range of problems concerning synchronous bandwidth management and quality of service guarantee are identified. To solve these problems, we present a dynamic bandwidth management scheme, a source handoff protocol and two approaches to handling destination handoffs. These schemes make handoffs transparent to mobile users; no degradation in quality of service will be observed during handoffs. The proposed solutions are compatible with the FDDI standards.
