CLAMP: Active queue management at wireless access points

This paper investigates the performance of CLAMP, a distributed algorithm to enhance the performance of TCP connections that terminate in a wireless access network. CLAMP works at a receiver to control a TCP sender by setting the TCP receiver’s advertised window limit. CLAMP provides explicit control over wireless link utilisation and queueing delay at the access point buffer, and can drastically increase the throughput of socalled short TCP flows with negligible loss in long TCP flow throughput.
