Abstract: This paper addresses how to use IXP2400, a kind of network processor, to build a high performance IPv4/IPv6 translation gateway. A detailed analysis of protocol address translation, table management and ALG about NAT-PT are then introduced. Some issues of network processor,such as hardware resource allocation and communication mechanism are discussed. The measurement of performance test proves the system’s efficiency.
