Extensions to the MARS model for IP Integrated Servies over ATM networks

摘要

The efficient support of the IP Integrated Services architecture (ITS) in ATM networks is nowadays a challenging research topic in the internetworking area. The integration of the two architectures needs the overcoming of the inconsistencies topic in the internetworking area. The integration of the two architectures needs the overcoming of the inconsistencies existing between their service models, in particular when consisering multicast comunicatiosn. The IIS architecture is based on the Resource Reservation Protocol (RSVP), IP multicast and RSVP rely on a receiver-oriented mode, where a receiver is not only capable of deciding whether to join or leave a multicast session, but it is also allowed to choose the associated QoS indipendently from the other participants. On the other hand, the ATM service model is sensder-oriented: the originating node of a multipoint session is the only entity allowed to add to delete leaf nodes.
