High Performance Network Processor-Based IPv4/IPv6 Transition Gateway
Network address/port/protocol translation (NAPT-PT) is a scheme dedicated to serve for pure IPv4 host to communicate with pure IPv6 host during the transition period. How to improve the IPv4/IPv6 transition performance is critical.This paper gives the design of high-performance transition gateway using hardware pipeline technology on an Intel IXP1200 evaluation board. Comparing with the performance of open sourced NAT-PT running on a PC,the evaluation results shows that network processor-based NAPT-PT's performance is obviously better than the NAT-PT running on a PC.
