Title : Prioritized PWDEDF Scheduling Algorithm for QoS Enhancement using Network Processor

Author Name : Anna sudha

Synopsis :

The main objective of this paper is to implement the Prioritized Weighted Deficit Earliest Departure First (PWDEDF) scheduling algorithm in a Network Processor (NP) based on router to enhance the multimedia applications. The performance is measured using Network Processor Simulator. The effectiveness of PWDEDF algorithm has been verified by simulations using Intel IXP 2400 NP. Network Processors are emerging as a very promising platform due to their capability of combining the flexibility of General-purpose processors with the high performance of hardware-based solutions. The results shows that, PWDEDF achieves reduction in jitter compared to EDF for different traffic type. Also PWDEDF has 97% less delay compared to EDF (Earliest Deadline First) scheduling algorithm for real time flows.
