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 negociate the tunnel with the broker. The negociation involves
authentication, authorization, tunnel information such as IP addresses,
prefixes when the client is a router, DNS information such as the NS for
the inverse zone corresponding to the delegated prefix, etc. Some
parameters may be proposed by the broker, such as the transport over UDP
IPv4 where an IPv4 NAT is found in the path between the client and the
broker. A mobile node implementing TSP can be connected to both IPv4 and
IPv6 networks whether he is on IPv4, IPv4 behind a NAT or on IPv6. A tunnel
broker may terminate the tunnels on remote tunnel servers or on itself.
This document describes the TSP protocol within the model of the tunnel
broker [3].
