Throughput improvement on RED mechanism

The Internet Engineering Task Force (IETF) had recommended the active queue management (AQM) scheme to solve the global synchronization problems in TCP/IP based networks for next generation routers. Since then, random early detection (RED) has been proposed as one of the AQM schemes. However, the major problems of the RED mechanism are low throughput achievement and high number of consecutive drop. We have proposed the extended drop slope random early detection (ExRED) mechanism in order to overcome these problems. The ExRED can reduce both the average number of dropped packets and the consecutive drop probability, hence network throughput is improved while all other advantages of RED are retained.
