A computer network is a collection of communicating computers and other devices, such as printers and smart phones. In order to communicate, the computers and devices must be connected by wired media like copper cables, optical fibers, or b ...

An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to transport another network protocol by Encapsulation (networking), encapsulation of its packet (information technology), packets.

tunnel broker server, the tunnel end-points. A major use of TSP is in
IPv6 transition mechanisms.
Parameter negotiation
The TSP protocol performs negotiation of the following parameters:
*User authentication using the
Simple Authentication and Security Layer (SASL) protocol
*Tunnel encapsulation for a variety of tunneling scenarios:
**IPv6 over IPv4 tunnels
**IPv4 over IPv6 tunnels
**IPv6 over UDP/IPv4 tunnels for built-in traversal of
network address translators (NAT)

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
