摘　　要：设计了一种将集群服务器NVS(network virtual server)接入到IPv4/IPv6环境中的机制,通过将协议转换内置到NVS接口机的内核中以提高协议处理速度,实现应用对底层具体协议的透明使用,原有高可用性、高可扩展性和负载均衡等多接口机软件不加修改即可使用。实验结果表明,该机制协议处理延迟小于通过NAT-PT网关实现的延迟,同时具有更高的吞吐量。This paper presents a mechanism to deal with IPv4/IPv6 packets, which improves the speed of protocol processing through placing the module of protocol translation into the kernel of the frontal subsystem of cluster server NVS （network virtual server）. This mechanism achieves that transparent applications of the underlying IP protocols and with high availability, high scalability, load balancing software of the frontal subsystem can be run on NVS without any modification. Experimental result shows that the delay of this mechanism is less than that through a NAT-PT gateway and it is characterized by high throughput.
