A Router Extension to Support Multicast in Differentiated Services Networks

摘要

This draft proposes an extension to the multicast routing table inrouters in order to achieve better support for using multicastwithin Differentiated Services (DS) networks. Only one additional DScodepoint for each virtual interface in the multicast routing tableis required to open up a variety of different uses, e.g., to solveresource provisioning problems or to support heterogeneous DiffServmulticast groups.
