Controlled IP Network for IP Full Services (series 6): IP Multicast (2) and several functions implemented by edge router

摘要

We are studying the provision of IP full service wherein multiple IP communication services are provided simultaneously on the controlled IP network; the operational responsibility of this network is assumed by communication carriers. This report describes essential techniques not realized by conventional edge routers, a new address transformation scheme for multicast (multi-cast NAT), a packet filter, priority control and how to divide the IP network into sub-IP networks.
