Abstract

The invention relates to the field of home gateway networks, in particular to a safeguard and optimization method of Internet protocol television (IPTV) professional work. The safeguard and optimization method of the IPTV professional work comprises correspondingly handling of addition and maintenance of a multicast source address table of the Internet group management protocol (IGMP) snooping and ip_mr_cache table to IGMP Join messages on a user from the local area network (LAN) side, correspondingly handling of deletion and maintenance of a multicast source address table of an IGMP snooping and ip_mr_cache table IGMP Leave messages or IGMP snooping / proxy time-out events specific to a user on the LAN side, and correspondingly handling of inquiry and matching of a multicast source address in aim Internet protocol (IP) and IGMP snooping and ip_mr_cache table on wide area network (WAN) side inflowing data flow. The safeguard and optimization method of the IPTV professional work has a function of achieving quality guarantee of IPTV high-performance services of a home gateway.

Description

technical field [0001] The invention relates to the field of home gateway networks, in particular to a method for guaranteeing and optimizing interactive network television services. Background technique [0002] With the rapid development of triple play and IPTV (Interactive Network Television) technology, home users and operators have higher and higher performance requirements for the IPTV of home gateway products. In the environment of P2P download (3-5M) + one SD IPTV1 (3M) + one HD (6-9M) IPTV2 environment, how to ensure the normal function of IPTV playback without mosaic and fast channel change is already an important measure of IPTV performance of a home gateway index parameter. If there is packet loss in the downlink data stream, it will cause mosaic phenomenon in the playing video. If there is packet loss in the uplink IGMP service message, it will cause the user to switch channels slowly, or the set-top box will have a black screen, and the flow will be cut off. ...
