Title
(EN) COMMUNICATION SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE COMMUNICATION
Abstract
(EN)
A communication system and method include an intermediate router arranged to facilitate communication between any of a plurality of communication nodes over a data communications network. The intermediate router receives communications over the data communications network from a transmitting communication node for a receiving communication node. The communication includes a unique identifier of the transmitting and receiving communication node. The intermediate router includes a routing database, and is arranged to record the unique identifier of the transmitting communication node against the network address of the transmitting communication node from which the communication was received. The intermediate router is also arranged to route communications to receiving nodes by obtaining the recorded network address associated with the unique identifier of the receiving node and routing the communication to the recorded network address. The unique identifier is independent of the network address of a node to cater for changed in network address.

L'invention concerne un système et un procédé de communication qui comprennent un routeur intermédiaire agencé pour faciliter une communication entre n'importe lesquels d'une pluralité de nœuds de communication sur un réseau de communication de données. Le routeur intermédiaire reçoit des communications sur le réseau de communication de données en provenance d'un nœud de communication émetteur à destination d'un nœud de communication récepteur. La communication comprend un identifiant unique des nœuds de communication émetteur et récepteur. Le routeur intermédiaire comprend une base de données de routage, et est agencé pour enregistrer l'identifiant unique du nœud de communication émetteur en regard de l'adresse réseau du nœud de communication émetteur duquel la communication a été reçue. Le routeur intermédiaire est aussi agencé pour router des communications vers des nœuds récepteurs par obtention de l'adresse réseau enregistré associé à l'identifiant unique du nœud récepteur et routage de la communication vers l'adresse réseau enregistrée. L'identifiant unique est indépendant de l'adresse réseau d'un nœud pour s'accommoder de changement d'adresse réseau.
