INCREASING TCP’S INITIAL CONGESTION WINDOW AS A MANIFEST CONSTANT TO SCALE

Abstract

This paper discusses some Transmission Control Protocol (TCP) congestion control algorithm, and proposes increasing TCP’s initial congestion window to at least fifteen segments (about 25 KB). Transmission Control Protocol (TCP) flow start with an initial congestion window at most three (3) segments or about 4 KB of data. Most Web transactions are short-lived and TCP’s initial congestion window is a critical parameter in determining how quickly flows can finish. The rapid growth of the internet in terms of the volume of activity and traffic it carries over the past decades represents a remarkable example of the scalability of the internet architecture, which in spite of the growth, the standard TCP’s initial congestion value has not changed.
