They handle the ports in each computer, or improve the reliability of the unicast communication. As examples, the U ser D atagram P rotocol ( UDP ) is a simple unicast transport protocol mainly for the port-handling, and the T ransmission C ontrol P rotocol ( TCP ) is intended for the reliable file transfer.

Abstract
The article presents an approach to optimize the multicast transport protocols. The main constraint of this procedure is the orthogonality (linear independence) of protocol parameters. Protocol parameters are variables defined for protocol classes, where the possible values of each parameter are protocol mechanisms, which serve the same goal in the multicast transport protocol. A multi-dimensional hyperspace of protocol parameters is stated, as a mathematical model of the optimization process where every transport protocol is represented as an individual point. A multicast transport Simulator for multiCast (SimCast) has been developed to describe the performance of the transport protocols and to simulate the operation of these protocols for reliable multicasting. The simulator supports the protocol analysis in the hyperspace of protocol parameters.
