Fair Scheduling for IPTV Services over EPON

One of the solutions for implementing IPTV service is applying the simple structure of Ethernet Passive Optical Networks. In such networks, scheduling algorithms play an important role for providing required levels of Quality of Service. Among them, Weighted Round Robin, is one of the commonly used ones. In this paper, a new weight allocation scheme is proposed in which, the weight of each queue would be allocated dynamically in each round. This strategy, reduces packet loss ratio for bursty traffics entering each queue. Simulation results with NS-2, show that the proposed scheme results in better packet loss ratio for bursty traffic compared to previous methods.
