    The communication channels have a variety of features in the communication system and networks, particularly wireless channels. It is used in transmissions between two nodes and deals with high error rates. Such errors that occur frequently which are not easy to be avoided, have the greatest effect on the performance of a network. So, it must be concluded that error rates are for different network conditions with use of different types of sliding windows techniques. In this thesis, error correcting techniques have been investigated based on a retransmission technique they used. One of the famous retransmission techniques is sliding windows technique, which it has three sub-algorithms called: stop and wait, selective repeat, and go back N. In this work, selective repeat and go back N algorithms were taken into account, but a stop and wait algorithm was not considered since it doesn't use any window structure in their retransmissions. Also, it always has a high delay amount with less performance compared to the selective repeat and go back N techniques. For this purpose, sliding window techniques have been implemented on Multi-Protocol Label Switching (MPLS) network platform which is simulated in MATLAB with all its details. In the simulation, all nodes running over a TCP/IP on MPLS network and nodes randomly send a number of data packets to any random node over the same network, which uses a path determined by the shortest path routing algorithm. Finally, the sliding window techniques have been studied and analyzed for their performances on the MPLS for the different traffic conditions, in terms of delay, throughput and packet loss rates. Indeed, the best sliding window technique was determined and suggested for different traffic types of the MPLS networks.
