Paper Abstract

This paper presents an integrated, server-based mechanism for the efficient support of the IP integrated services (IIS) model in ATM networks, namely the multicast integration server (MIS) architecture. Instead of viewing IP-ATM multicast address resolution and QoS support separately, the approach in this paper is to consider such issues in an integrated manner. The multicast integration server is capable of IP multicast to ATM NSAP address resolution using the easy multicast routing through ATM clouds (EARTH) protocol, as well as of QoS management using the resource reservation protocol (RSVP). With the use of EARTH, several ATM point-to-multipoint connections with different QoS parameters can be associated to a single IP multicast address. AN RSVP server within the MIS is used to distribute RSVP messages inside the ATM cloud and to set the corresponding QoS state in the address resolution table of EARTH. In addition, this paper defines a quantized heterogeneity model which supports, together with the MIS, advanced IIS features as QoS heterogeneity and dynamic QoS changes in IP-ATM networks.
