A study on congestion avoidance using TCL script

As company intranets continue to grow it is increasingly important that network Administrators are aware of and have a handle on the different types of traffic that is traversing their networks. TCP(Transmission Control Protocol) is a protocol used along with the Internet Protocol (IP) to send data in the form of packets between computers over the Internet. TCP considers all packet timeouts in wired networks as due to network congestion and not to bit errors. It therefore considers all packet losses as due to congestion and consequently reduces the burst of packet, diminishing at the same time the network throughput. In Existing work the classical Slow-start algorithm along with reserved bits and SNR ratio has been developed for this problem. But Slow-start algorithm takes some time to receive the acknowledgement from the receiver. This paper proposes a new TCP RED congestion avoidance algorithm and a tcl script appropriate for wireless as well as wired networks and is capable of distinguishing congestion losses from error losses proactively. Proposed RED algorithm won't wait for the packet's acknowledgement.
