Organization-Level Control of Excessive Internet Downloads

Abstract

The control of excessive downloads by rogue users in organizational LANs is the subject of this work. Two mechanisms have been used in order to accomplish this. The first mechanism, is TCP rate control (TCR), it is a receiver-based flow control technique that can be used to effectively rate limit rogue users' flows, making more bandwidth available to regular users. The second mechanism, admission control reduces the bandwidth wastage due to users disconnecting out of impatience when user goodputs are low. Using simulation-based experiments, it has been demonstrated that the composite technique, exclusive TCP rate and admission control (xTRAC) provides seamless control of rogue users, while improving response times and goodput by upto 58% during overload. In this way regular users are incentivized and rogue users are penalized leading to long-term control of users.
