Abstract

Internet Protocol Television (IPTV) is a service to present digital TV over Internet. The IPTV network architecture consists of two main components: core network and access network. Many types of access networks can be used for IPTV including Ethernet PON (EPON). In this paper, a new mechanism is proposed for bandwidth allocation to various IPTV services over the EPON that decreases IPTV packet loss. This mechanism is implemented in optical line terminal (OLT) and weights are allotted to queues in the OLT to reduce packet loss. Then, weighted round robin (WRR) is used to scheduling IPTV packets.
