一种高性能IPv6/IPv4安全网关

Secured IPv6/IPv4 Gateway with High Performance

在IPv4/IPv6并存过渡时期提供强有力的网络安全保障,是实现面向NGI(next generation Internet)平滑演进和发展的关键。在NAT-PT协议转换和流量负载均衡等技术分析的基础之上,提出了一种具备IPv4/IPv6异构网络边界访问控制功能的高性能安全网关模型NAPTSG,详细论述了其系统设计思路,并且给出了其原型的实现及测试情况。

To ensure the network security in the period of IPv4/IPv6 transition and co-existence is the key for NGI evolution.This paper proposes a novel secure gateway system model based on NAT/PT-NAPTSG,which is aimed at providing the function of high-performance access control and interconnections on the IPv4/IPv6 network border.The considerations about its design is discussed in detail.In the last part of the(paper),the working progress of prototype and testing is described.
