Abstract
A transaction-based routing system applies particular routing procedures wherein one example uses Global Title Translation (“GTT”) techniques for a connection-oriented packet network. The network comprises a plurality of nodes including intermediate and edge nodes. Initially, intermediate nodes in the network receive data messages including originating node identifiers and first translation requests from originating edge nodes and route these messages, based on the first translation requests, over selected network routing paths to destination edge nodes. In response, intermediate nodes receive response data messages including the originating node identifiers and second translation requests from destination edge nodes and route these response messages, based on the second translation requests, over selected network routing paths to the originating nodes. These routing procedures help reduce the complexity of logical connectivity in the network.
