This article describes how control theory has been used to address the question of how to size the buffers in core Internet routers. Control theory aims to predict whether the net...
In the past two years, several papers have proposed rules that suggest two to five orders of magnitude reduction in Internet core router buffers. Others present scenarios where bu...
All Internet routers contain buffers to hold packets during times of congestion. Today, the size of the buffers is determined by the dynamics of TCP’s congestion control algor...
— In this paper we explore the stabilization of closed invariant sets for passive systems, and present conditions under which a passivity-based feedback makes the set stable, sem...
Internet routers require buffers to hold packets during times of congestion. The buffers need to be fast, and so ideally they should be small enough to use fast memory technologie...
