SYSTEM AND METHOD FOR COMMUNICATION BETWEEN HETEROGENEOUS NETWORKS

摘要

There are provided communication systems and methods over a network. The communication method includes updating a mapping table so as to map a first address available in a network where a client is located and a second address available in a network where a server is located, and relaying communication according to a protocol managing sessions between the client and the server on the basis of the updated mapping table. As the proxy server shares address conversion and protocol conversion functions with the NAT-PT, it is possible to reduce the loads of the NAT-PT.
