Controlling Inbound Traffic

This work considers the problem of prioritizing the inbound TCP traffic of an organization network. The objective is to allocate dynamically a specific share of the incoming link bandwidth to a high priority inbound TCP traffic. However, if the high priority TCP traffic does not fully use its dedicated share, the low priority TCP traffic may take advantage of the unused bandwidth. Up to today, a network administrator has no control over the inbound traffic if the Internet Service Provider does not offer some QoS mechanism. Three different techniques are proposed and evaluated: a proxy flow controller (PFC), a fake ECN flow controller (FECN), and a fake bottleneck (FBK). These techniques allow a network administrator to prioritize the inbound traffic and allocate dynamically the bandwidth without any external cooperation or deployment of any special infrastructure. No change in the TCP code is required. No infrastructure such as Diffserv or MPLS is required. The ns-2 simulator is used ...
