Abstract:
1. A method for use in a peer-to-peer hybrid network comprising: identifying, by a first source node, a first set of nodes linking the first source node to a target node and a second set of nodes linking a second source node to the target node; determining, by the first source node, whether the first and second source nodes are in a single network or in different networks using the first and second sets of nodes, wherein the determining includes identifying a set of internal boundary nodes based on the first and second sets and determining whether a size of the set of internal boundary nodes is greater than one, wherein the first and second source nodes are in different networks if the size of the set of internal boundary nodes is greater than one; identifying, by the first source node, at least one network address that must be used when sending communications from the first source node to the second source node, wherein the network address is included in at least one of the first and second sets; and communicating, by the first source node, via the at least one network address with the second source node.
