Aspects on Performance Measurements of TCP Traffic and Its Reflection into Control Theory
2002 (English)In: Proceedings of Reglermöte 2002, 2002Conference paper (Other academic)
One of the challenges of the communication world today is to improve the performance of Internet traffic for the changing traffic scenarios of today, e.g., radio transmissions. This leaves us with the question of what good performance is and how we measure it. This work will discuss some issues of performance when using TCP and also present some of the measures that are used today. We will then discuss this matter from the perspective of a bottleneck queue and present a measure that can be used from that view point in the network. This measure is illustrated by comparing two versions of TCP and is used as a base for a discussion of what models will be needed to actually achieve the goals that we have. A control structure is presented that currently is used as a base for the development of a mathematical description of the system. We use the dropping of packets as a control signal, as is done by e.g. ~ RED, and the output signal is the queue length.
