Abstract
High throughput and reduced delays are the basic necessities of next-generation networks which use multimedia applications (ftp, videoconferencing, VoIP, etc.). In order to make the network function efficiently, these necessities should be improved and maintained at a desired level. This provides a better quality of service (QoS) to the traffic which ensures a maximum customers’ satisfaction. These basic necessities are provided by using the appropriate scheduler mechanism at the router. The data are handled in the form of packets in the required manner. Presently, the scheduler mechanisms which are used have still some drawbacks in them. Therefore, they cannot handle the packets in a proper way in next-generation networks which are real-time applications. In this paper, various existing scheduling techniques are explained like First-In First-Out (FIFO), Priority Queue (PQ), Fair Queue (FQ), and Deficit Weighted Round Robin (DWRR). A new scheduling technique is introduced in this paper which is a combination of PQ and DWRR. Then a comparative analysis of the scheduling technique, i.e., PQ and proposed scheduling technique, i.e., PQDWRR is performed. PQDWRR technique provides a better QoS than the existing queuing mechanisms.
