Method and system for communication using a partial designated transit list

A communication system includes a source PNNI node. The system includes a destination PNNI node. The system includes a network having logical group nodes representing peer groups through which the source node and the destination node communicate by establishing an SPVC using a DTL which identifies the group nodes representing the peer groups with only a partial node ID. A method for communicating includes the steps of forming a DTL which identifies logical group nodes representing peer groups with only a partial node ID. There is the step of establishing an SPVC using the DTL through which a source PNNI node and a destination PNNI node of a network communicate.
