Segment based model for TCP protocol optimization: Enhancing the bandwidth and congestion

Abstract

This paper aims to provide an efficient segment-based model for the Transmission Control Protocol (TCP) protocol to improve the transmission mechanism by enhancing both bandwidth utilization and congestion. The study puts forward a segment-based model that encompassed three phases, namely: network environment evaluation to calculate bandwidth, which is the Round Tip Time (RTT) independence, organizing packets into groups of segments, and transmission of segments within a fraction of a millisecond delay with the predefined speed. Network evaluation is done by considering the capacity of the network and the time taken for some insignificant packets to be transmitted to the server. Packet segmentation organizes several packets into a group at predefined speed, which then will be transmitted to the destination at a fraction of a millisecond. Experimental results using the segment-based model for the TCP protocol show that the proposed solution significantly improves the transmission mechanism of TCP. Further, the results of the experiment show that bandwidth is utilized to near the same value of available bandwidth. Furthermore, the transmission time is improved compared to previous models of TCP. The proposed segment-based model allows for the TCP protocol to utilize better bandwidth and avoid congestion in a network while transmitting data. The transmission time will decrease significantly, allowing more data to be transferred, resulting in the robust reliability of the TCP protocol.
