Claim:
1. A method of discovering global topology in a barrage relay network comprising: receiving, at a receiving node, a first message on a first logical channel from a first node; updating, at the receiving node, a topology table with a first set of topology information contained in the first message; receiving, at the receiving node, a second message on a second logical channel from a second node, the second logical channel being different from the first logical channel, the second message being periodically broadcast network wide by the second node, the second message comprising a unique identifier associated with a node in the barrage relay network and a request to transmit local topology information, the unique identifier identifying the node as a destination of the second message; determining, at the receiving node, whether the unique identifier identifies the receiving node; and when the unique identifier does not identify the receiving node: when the unique identifier identifies the receiving node:
