In the present day computer networks quality of service is a major issue, which invariably depends on the network performance under various network constraints such as flow control, error control, bandwidth, data traffic, buffer handling etc. In this paper, the authors are analyzing the effect of timer timeout and Packet length on the performance of error control protocols and conclusions are drawn. In computer networks, mostly they come across three types of errors: Lost frames, Lost Acknowledgements and Delayed Acknowledgements. Most Error Control techniques are based on either Error Detection Scheme (e.g., Parity checks, CRC), or Retransmission Scheme.
