Edge-based active queue management

In this paper, a new framework of active queue management, namely, edge-based active queue management (EAQM), is proposed. Conventional AQM schemes are required to be deployed at all routers in the network, and this involves significant upgrading to current drop-tail routers. The new approach only needs to modify the edge routers and at the same time provides similar or better performance as compared to conventional AQM schemes. Furthermore, EAQM can reduce the throughput bias against TCP connections with longer round trip times, and this cannot be achieved by current available AQM approaches.
