Congestion Control Method by Measuring Queue Length and Traffic Load in Asynchronous Delivery Mode Network

摘要

1. The technical field to which the invention described in the claims belongs;Congestion control method by measuring queue length and traffic load in asynchronous delivery mode network.;2. Technical challenges to be solved by the invention;We intend to perform congestion detection and congestion control strictly and efficiently by using parameters related to load index and one queue length.;3. The point of the solution of the invention;If the current queue length is greater than the threshold value and the traffic load is large, the explicit rate is assigned as a fair allocation value to reduce the explicit rate. If the current queue length is above the threshold value, If the current queue length is less than the threshold value and the traffic load is small, the explicit rate is assigned as a fair allocation value to increase the explicit rate, and if the current queue length is less than the threshold Value and the traffic load is large, the explicit rate is assigned to the average allowed cell rate multiplied by the end-to-end hops index.;4. Important Uses of the Invention;Used to control traffic data congestion of ATM switching system.
