Tunnel Setup Protocol
From Wikipedia, the free encyclopedia
In computer networking, Tunnel Setup Protocol (TSP) is a signalling protocol used to negotiate tunnel setup parameters between two tunnel end-points. TSP is implemented in a client-server architecture.
[edit] Current Revision
The current revision of the TSP protocol (2.0.1) allows authentication and negotiation of the following tunneling modes:
- IPv6-In-IPv4, allowing IPv6 connectivity on native IPv4 networks.
- IPv6-In-UDP-In-IPv4, allowing IPv6 connectivity through NAT devices on native IPv4 networks.
- IPv4-In-IPv6, allowing IPv4 connectivity on native IPv6 networks.
[edit] TSP Session
A TSP session is initiated by the TSP client in the goal of establishing an end-to-end tunnel with the TSP server (tunnel broker). The session consists of a basic exchange of XML using TCP or UDP. After negotiation of tunnel setup parameters has been done, the session is terminated and the client undertakes the task of configuring its local tunnel endpoint.
