New Design of 4over6 Mechanism Based on OpenSolaris

 Abstract

 The 4over6 mechanism is a mechanism put forward by the Computer Network and Protocol Testing Laboratory of Tsinghua University. The aim of this mechanism is to interconnect IPv4 networks over IPv6 backbones. In this mechanism it concerns two aspects: the control plane and the data plane. In the control plane the 4over6 mechanism extends BGP-MP protocol to carry the tunnel end information to the other side of the IPv6 backbone to setup of a stateless 4over6 tunnel on the dual-stack Provider Edge (PE) router. Based on the 4over6 tunnel, the data plane focuses on the data packet forwarding process with encapsulation and decapsulation. Solaris is an open source operating system developed by Sun Microsystems. In this document, we will give out the detail design method of 4over6 mechanism based on Solaris.
