A Packet Dropping Strategy Based on C-R Model

As the common queue management strategy of Router, queue trail dropping has serious limitations such as full queue, whole synchronization and dead lock which leads to passive congestion management after the queue is full. Therefore the strategy easily leads to network congestion even crash. There are some good research fruits of active queue management (AQM) in keeping short queue length and keeping reasonable balance between high throughput and low time delay. Whereas in many of its arithmetic, there are still certain shortages, for example, the improper queue management arithmetic might lead to the problems of whole synchronization linked by TCP, the queue being full for a long time and the problem of equity in managing the outburst operation. Based on C-R fuzzy reasoning strategy model, this paper designed an aptitude pocket dropping strategy to further optimize the property of Router. The emulational experiments indicate that the property of the strategy, which can better resist the outburst interference, is better than that of classical RED arithmetic.
