RED (Random Early Detection) is the most popular active queue management algorithm, although it has some weaknesses. Recently, another active queue management algorithm, BLUE, was proposed and shown that it is more successful in controlling the queue length when high number of flows are active on ECN (Explicit Congestion Notification) capable networks. In this paper, RED and BLUE algorithms are evaluated for different levels of RTTs, with/without ECN support. It is shown that BLUE on ECN incapable networks is not as successful as on ECN capable networks.
