System for achieving end-to-end quality guarantee of IPTV unicast service

摘要: The invention relates to a system for achieving an end-to-end quality guarantee of IPTV unicast service. comprises node monitoring module, link fault positioning and analyzing module statistic analysis wherein the edge unit used requested broadcast program source sent from equipment access network, is performing on result information topological user through branch-and-bound algorithm according warning data obtained by comprehensive module. Due adoption service, links can be automatically gathered performed so that operator know about state nodes fully, flow having broadcasting problem recorded, unicast-type faults fast solved, has wider application range.
