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.

摘要： A method for more efficiently operating a network, and more particularly, for discovery of a path maximum transmission unit (PMTU) between nodes on an IP network, is provided. The method includes (a) comparing the size of a received packet with a maximum transmission unit (MTU) of a next link; and (b) if the size of the received packet is greater than the MTU of the next link, generating an error message, transmitting the generated error message to a source node, generating a test message of the size of the MTU of the next link, and transmitting the generated test message to a destination node. According to the PMTU discovery method, a PMTU can be determined in a shorter time, and it is possible to minimize the use of network resources.
