description A system and method for providing link, node, and PG policy based routing in PNNI based ATM networks is disclosed. A computer implemented method signals and routes a call in the network. Upon detecting the call's arrival, its service request is accessed. Upon determining that the service request relates to an attribute of a link, a routing path is sought that conforms to the service request, as by accessing information relating to the routing path and comparing the information to the service request. A conforming routing path is selected, and the call is routed via that path. A computer implemented method advertises an attribute of links, nodes, policies, etc. Data relating to the route's attribute can be provided to a node as a GAT IE component of a PNNI signaling setup message for multi-peer group networks, and advertised using PTSEs within a peer group.
