SYSTEM AND METHOD FOR SUPPORTING FLEXIBLE OVERLAYS AND MOBILITY IN IP COMMUNICATION AND COMPUTER NETWORKS

摘要

There is provided a system and method for providing a simple yet flexible overlay network on top of any IP networks to enable diverse network applications whereby much of the rigidities of IP protocol suite are eliminated without any modifications to the applications. In particular, the system includes: a plurality of c-nodes; one or more source terminal nodes connected to an IP network; and one or more destination terminal nodes connected to the IP network. Here, the source terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. More specifically, a method employing the system utilizes the concept of connection ID and headers that can be inserted anywhere in the IP packet.
