A method and system of enabling communication between peers in a peer-to-peer (P2P) network in the presence of network address translators (NAT) i.e. NAT traversal. The method includes: assigning a unique peer identifier to each one of the plurality of peers in the P2P network; establishing an overlay topology connecting each peer to a subset of the plurality of peers in a structured connection pattern based on the unique peer identifier of each peer, each one of the plurality of peers having more connections to close peers and fewer connections to distant peers; and routing messages between peers through the established overlay topology. Aspects of the invention include assigning the unique peer identifier comprising hashing/coding an attribute (network address, MAC address, serial number) of the peers. The partial mesh of connections (overlay) strikes a balance between a ring overlay where each peers is connected only to two neighbour peers and a full mesh overlay where all pairs of peers are connected while still allowing messages to be delivered across NATs. |
