Transmission Control Protocol (TCP) is built on the concept of self-clocking technique and this concept based on several characteristics. The slow-start mechanism represents the prime technique for usage the operative network resource. The objective of the slow start mechanism is to create a TCP connection in an optimal state - run for network route rapidly without giving a disproportionate load to the network. Due to the rate of packet transferred is limited by the bandwidth of the narrowest bottleneck alongside the connection pipe, then, the transferring rate cannot exceed this bandwidth and the maximum rate competitions the permissible bandwidth of the link that own narrowest bandwidth over end-to-end connections. In large bandwidth networks, the mechanism of slow-start does not perform suitably and may cause considerable degradation in network performance. Therefore, it's necessary to develop a new slow-start technique that can increase the packet transferring over large bandwidth links environments. This article investigates the behaviour of TCP protocol after applying a technique based on using available bandwidth estimation to detect the current level of the network slow-start threshold (ssthresh) in high capacity links used over industrial application.
