COMMUNICATION SYSTEM AND METHOD
First Claim
1. A communication system arranged to facilitate communication between a first and a second communication nodes over a data communications network, each of the first and second communication nodes including a unique identifier, the unique identifier being independent of any network address assigned to the communication node, comprising:
- a client application executable at each of the first and second communication nodes and configured to include the unique identifier of a particular communication node and a recipient node within communications over the data communication network;
a routing database configured to store the unique identifier of a communication node against the network address of the communication node; and
a router configured to route communications to the communications nodes in dependence on the network address recorded against their respective unique identifiers in the routing database.

Abstract
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.

4. A communication system comprising:
-
an intermediate router; a plurality of communication nodes including at least a first communication node and a second communication node, each of the first and second communication nodes including a unique identifier and being arranged to include their respective unique identifier within communications with the intermediate router, the unique identifier being independent of a network address assigned to the communication node, wherein the intermediate router is arranged to facilitate communication between any of the communication nodes over a data communications network, the intermediate router being arranged to receive communications over the data communications network from a transmitting one of the plurality of the communication nodes for a receiving one of the plurality of communication nodes; and a routing database 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 being 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. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A communications method comprising:
-
assigning a unique identifier to each of a plurality of communication nodes, the unique identifier being independent of a network address associated with the communication node; addressing communications to nodes using the unique identifier of the recipient communication node and identifying the origin of the communications using the unique identifier of the originating communication node; directing the addressed communications to an intermediate router; recording, at the intermediate router, the unique identifier and network address of the originating node; identifying, at the intermediate router, the network address recorded against the unique identifier of the recipient node; and routing the communication to the identified network address. - View Dependent Claims (12, 13, 14)
