Abstract
A routing system for implementing a service and topology exchange protocol (STEP) comprises a primary STEP server configured to maintain a STEP repository and a plurality of routers, each router including a STEP client in communication with the primary STEP server. The STEP client of each router is configured to transmit, using the service and topology exchange protocol, service and topology state information for at least one route or service available through the router to the primary STEP server for storage in the STEP repository. The primary STEP server is configured to determine, for each router, whether the STEP repository includes any service and topology state information changes for the router based at least in part on the service and topology state information received from the routers and to transmit to the STEP client of each router for which there are service and topology state information changes, using the service and topology exchange protocol, only the service and topology state information changes.
