Messenger communication

The current model of computer communication is based on Shannon's (1949) model consisting of a sender, a channel and a recipient, where the sender sends a packet of data, along a channel to the recipient. Usually there are two channels, one each direction, allowing data flow in both directions. A protocol can be understood as a procedure which enhances the quality of the message exchange. Messengers constitute a new and exciting methodology for implementing communication across a network. Messengers, and messenger communications have existed in embryonic forms for many years. At its simplest level, a messenger is an autonomous program that can spawn other programs and which can be transported and executed either across a network or on the local machine.
