[jira] [Created] (DISPATCH-584) Large, highly redundant router networks generate excessive inter-router message traffic

Ted Ross created DISPATCH-584:
---------------------------------

             Summary: Large, highly redundant router networks generate excessive inter-router message traffic
                 Key: DISPATCH-584
                 URL: https://issues.apache.org/jira/browse/DISPATCH-584
             Project: Qpid Dispatch
          Issue Type: Improvement
          Components: Routing Engine
    Affects Versions: 0.7.0
            Reporter: Ted Ross
            Assignee: Ted Ross


When the router network is discovering and maintaining the distributed understanding of the topology, router-advertisement (RA) messages are flooded across the network.  Flooded messages are multicast without the tree-trimming done using valid-origins.  In very redundant networks, many distinct paths are followed for these messages, using excessive amounts of network and CPU bandwidth.
