TOPOLOGY DISCOVERY FOR AN APPLICATION LAYER MESSAGING PROTOCOL WITH HOP-BY-HOP ROUTING

摘要

A technique for discovering topological information in connection with an application layer messaging protocol that uses hop-by-hop routing is disclosed. An exemplary network element provided by the present disclosure comprises a memory in which a routing table is stored. The routing table includes one or more table entries, with each table entry associating a hop supported by the network element with a message destination potentially reachable via that hop. The network element further comprises at least one processor configured to determine topological information about a local logical topography of the network element and to trigger transmission of the topological information to the hops defined in the routing table. Responsive to receipt of the topological information, the hops may modify their local routing table so as to arrive at improved routing decisions.
