An IPTV Video Stream Transmission Algorithm Based on Multicast and QoS

Abstract

This paper introduces the basic concepts of IPTV and multicast technology, and proposes a USDP algorithm to overcome the shortcomings of MSDP algorithm. After the simulation experiment has achieved good results, according to the USDP algorithm, a scheme of IPTV bearer network based on multicast and QOS technology is proposed. After the implementation of the scheme, the network data are collected and analyzed. It is verified that the scheme reduces the network traffic load, reduces the transmission delay and ensures the normal operation of key services.
