Abstract : Congestion control is a distributed algorithm to share network bandwidth among competing users on the Internet. In the common case, quick response time for mice trafﬁc (HTTP trafﬁc) is desired when mixed with elephant trafﬁc (FTP trafﬁc). The current approach using loss-based with Additive Increase, Multiplicative Decrease (AIMD) is too greedy and eventually, most of the network bandwidth would be consumed by elephant trafﬁc. As a result, it causes longer response time for mice trafﬁc because there is no room left at the routers. MaxNet is a new TCP congestion control architecture using an explicit signal to control transmission rate at the source node. In this paper, we show that MaxNet can control well the queue length at routers and therefore the response time to HTTP trafﬁc is several times faster than with TCP Reno/RED.
