Vol. 17  No. 7  pp. 21-30


The network performance is affected due to congestion. The congestion is occurred due to overloading data over low capacity handling node. The objective of this research is to investigate the applications (like email, file transferring/downloading, web browsing and remote login) performance in the perspective of application reply time, throughput, queuing delay, Transmission Control Protocol (TCP) Delay over Point-To-Point Protocol E1 with TCP default and variable window sizes (8K, 32K, and 64K). This study also dealt with ATM and Frame Relay E1 links with Nagle’s Algorithm for small data packets with large size TCP/IP headers delivery over the internet. The extent of this research is incorporated scenario based investigation of various protocols utilized at end-to-end and intermediary devices using OPNET (Optimized Network Engineering Tool) network simulator.
