Design and Implementation of the Mechanism to Process IPv4/IPv6 Request Packets for Cluster Server

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.
