In conventional networks lack of reliable and efficient transmission of data over unreliable channels that can lose, reorder and duplicate messages due to router or receiver limited buffer space, are retransmitted by the source. These scenarios usually data blocks contain error detection codes to detect whether an error has occurred during data transmission or not. If an error is detected, the receiver can try to fix the error if the received data has enough redundant bits or request a retransmission of data, for fulfill this requirement sliding window protocol is use. This paper shows calculated link utilization is better than observed link utilization for sliding window protocol using Deft Netz2.0 network simulation.
