computer networking
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are ...

IP tunnel
An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to transport another network protocol by encapsulation of its packets.
IP tunnels are often used for connecting two disjoint IP networks ...

Parameter negotiation
The TSP protocol performs negotiation of the following parameters:

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
