The management of transferring the message has to fulfill the requirements volume of traffic to be transmitted as to prevent congestions for reducing the transmission delays. These two requirements in general are contradictory. The most favorable process of sending the messages is a key issue for the quality of the information services. Routing in networks, applying shortest path algorithms widely used in communication protocols in WIDE AREA NETWORK.
