Fairness Evaluation of a DSCP Based Scheduling Algorithm for Real-Time Traffic in Differentiated Service Networks

Sabyasachi Mukherjee and O. S. Khanna

Abstract—It is a very vital factor to allocate the resources for improving the QoS (Quality of service) for any network carrying various types of traffic. Real-time applications, such as video conferences, are in the most important to get the benefit of QoS adaptation. Several scheduling disciplines are employed at the router to guarantee the QoS of the network. Each scheduling discipline has its pros and cons. DiffServ (Differentiated Services) is an IP based QoS support framework that differentiates between different classes of traffic. The function of the core router of the network is to forward packets as per the per-hop behavior associated with the DSCP (Differentiated services code point) value.
Weighted Fair Queuing scheduling discipline when merged with DSCP for traffic classification, maintain fairness of Qos. The common scheduling mechanisms are first-in-first-out (FIFO), priority queuing (PQ), and weighted fair queuing (WFQ). In this paper performance of various scheduling disciplines for real-time traffic like video was simulated using OPNET IT Guru, and it was concluded that, WFQ when merged with DSCP is a better method of queuing.

Index Terms—FIFO, PQ, WFQ, DSCP, PHB, QoS, differentiated services, OPNET.
