Tunnel Broker System Using IPv4 Anycast
نویسندگان
چکیده
Tunnel Broker model, as defined in RFC3053, is a solution to the automation of IPv6 address assignment and IPv6 over IPv4 tunnel management. Tunnel server selection and fault tolerance are two big problems for a Tunnel Broker system. Anycast makes it possible to solve the tunnel server selection problem and improve the system’s fault tolerance. This paper proposes an architecture of the Tunnel Broker system using IPv4 anycast. In the proposed architecture a user could hook up to the IPv6 network via the nearest tunnel server, and some failures in the Tunnel Broker system could be recovered in some circumstances.

A Multihoming Based IPv4/IPv6 Transition Approach
How to make IPv4 users utilize IPv6 applications is a typical scenario of the IPv4/IPv6 inter-operation. Nowadays, Tunnel Broker and 6to4 tunnel mechanisms are the popular solutions for this problem. This paper proposes a multihoming based algorithm MI46 to integrate Tunnel Broker and 6to4 tunnel mechanism. It overcomes the shortcomings of both Tunnel Broker and the 6to4 tunnel mechanism to for...
متن کاملIPv6 Tunnel Broker with the Tunnel Setup Protocol (TSP)
A tunnel broker with the Tunnel Setup Protocol (TSP) enables the establishment of tunnels of various inner protocols, such as IPv6 or IPv4, inside various outer protocols packets, such as IPv4, IPv6, or UDP over IPv4 for IPv4 NAT traversal. The control protocol (TSP) is used by the tunnel client to negotiate the tunnel with the broker. A mobile node implementing TSP can be connected to both IPv...
متن کاملRFC 3053 IPv 6
The IPv6 global Internet as of today uses a lot of tunnels over the existing IPv4 infrastructure. Those tunnels are difficult to configure and maintain in a large scale environment. The 6bone has proven that large sites and Internet Service Providers (ISPs) can do it, but this process is too complex for the isolated end user who already has an IPv4 connection and would like to enter the IPv6 wo...

متن کاملIPv4/IPv6 Transition Mechanisms
Currently, the Internet consists of native IPv4 (IPv4-only), native IPv6, and IPv4/IPv6 dual networks. Unfortunately, IPv4 and IPv6 are incompatible protocols. When both IP versions are available and the users of Internet want to connect without any restrictions, a transition mechanism is required. During the time of migration from IPv4 to IPv6 networks, a number of transition mechanisms have b...
