Interdomain Multicast Routing Support for Integrated Services Networks

This document describes an architecture for interdomain multicast routing support of integrated services networks. The key features of this architecture are a multicast route setup protocol and local route construction agents. Together, these two components enable multicast routing to install alternate paths and pinned routes on behalf of receivers that request these services. Internet Draft Multicast Routing Support March 1997 1 Introduction The Internet, with its best-effort service and adaptive routing, has been extremely successful supporting elastic applications [1]. However, best effort service can result in large, and widely varying, end-to-end packet delays. To better support real-time and other inelastic applications for which such vagaries are detrimental, the IETF is in the process of adopting extensions to the Internet's service model and architecture that would allow flows or flow aggregates to reserve specific qualities of service (QoS). These extensions, commonly known...
