CA 2611146

The present invention discloses a system and method for data communication. In the system and method for data communication, a part of communication peers in the communication system are assigned as super peers, and each super peer forwards message according to its route table. When a communication peer logs in the system, network information of the logged communication peer is saved in a super peer which is logically closest to the logged communication peer through messages forwarded among every super peer. And when an origination communication peer searches for a destination communication peer, the network information of the destination communication peer is saved in a super peer which is logically closest to the destination communication peer through the message forwarded among every super peer in super peer layer. The origination communication peer establishes connection with the destination communication peer based on the network information of the destination communication peer, and implements the data communication through the connection established.

L'invention concerne un système et un procédé de communication de données. Au cours de ce procédé, il est confirmé qu'une partie des noeuds de communication sont des supers noeuds dans le système, et ces supers noeuds acheminent les messages en fonction d'une table de routage respective. Ainsi, lorsqu'un noeud de communication enregistre le système, les informations réseau de ce noeud de communication sont stockées dans le super noeud dont la logique ressemble le plus à celle dudit noeud de communication, par acheminement de messages entre les supers noeuds respectifs. Lorsque le noeud de communication source cherche à obtenir des informations sur le noeud de destination, les informations réseau du noeud de communication de destination sont renvoyées au noeud de communication source par le super noeud dont la logique ressemble le plus à celle du noeud de communication de destination, par acheminement de messages entre les supers noeuds respectifs dans la couche des supers noeuds. Le noeud source établit la connexion avec le noeud de communication de destination, au moyen des informations réseau acquises du noeud de communication de destination, puis effectue la communication de données à l'aide de ladite connexion.
