A Novel Queue Management Algorithm INRIO-C Based on Differentiated Services

2014 
Diff Serv network architecture is the first choice for QoS of network. As a network buffer resource management, active queue management is the key technology to differentiated services. On the basis of the RIO-C (RED with IN/OUT and couple queue), this paper proposes a queue management algorithm INRIO-C (Improved nonlinear RIO-C). This algorithm takes nonlinear characteristics between the average length of the queue and packets loss probability into consideration, and proposes piecewise smooth discarding functions. By NS-2 simulation, INRIO-C algorithm is proved that it can improve system stability, increase the priority queue throughput, reduce packets loss rate of the system, and increase system capacity for burst traffic.
