IPTV-RM: A Resources Monitoring Architecture for P2P IPTV Systems

Abstract

Resources monitoring is an important problem of the overall efficient usage and control of P2P IPTV systems. The resources of IPTV can include all distributing servers, programs and peers. Several researches have tried to address this issue, but most of them illuminated P2P traffic characterization, identification and user behavior. The main contributions of this paper are twofold. Firstly, a resources monitoring architecture for P2P IPTV systems, IPTV-RM, was presented based on previous work. The monitoring architecture employs a hierarchical structure and provides systemic monitoring including resources discovery, relative information extraction and analysis, trace and location. It gives a systematic framework for IPTV resources monitoring. Secondly, a distributed program crawling system (DMP-Crawler) was first proposed to collect information of programs, and a peer crawling system was put forward to harvest peers of a program. The results show that they are efficient and can be used for resource collection of other P2P system.
