Problems solved by technology

Since the above fault diagnosis method needs to deploy more than two IPTV monitoring probes to determine whether the service quality problem is caused by the video server or the intermediate node of the IP network, it increases the network maintenance personnel’s time for IPTV troubleshooting to a certain extent. equipment cost, and installation complexity and cost

Embodiment 1

[0027] see image 3 , the present invention discloses a method for fault isolation of a video server and an IP network in an IPTV network, said method comprising the steps of:

[0028] [Step S1] Passively capture video media stream data at an intermediate point of an IPTV network through the acquisition device;

[0029] [step S2] process the video media stream data layer by layer according to the IPTV protocol stack, and count the number of MPEG-TS layer media packet loss Nt and the packet loss rate Rt, and the number of RTP layer packet loss Nr and the packet loss rate Rr;

[0030] [Step S3] In several sampling periods, if Nt>T1 and Nr=0, it is judged that there is packet loss or encoding error in the video server, but there is no packet loss in the IP network, and a corresponding expert system prompt will be generated on the user interface ; Wherein, T1 is the MPEG-TS media packet loss alarm threshold set; if Nt>T1 and Nr=0 is not established, turn to step S4;

[0031] [St...

Abstract

The invention discloses a failure isolation method and a failure isolation system for a video server and an Internet protocol (IP) network in an Internet protocol television (IPTV) network. The method comprises the following steps of: performing passive video media stream data capturing at a certain intermediate point of the IPTV network by using acquisition equipment; processing video media stream data layer by layer according to an IPTV protocol stack, and calculating a lost media packet number Nt and a media packet loss rate Rt of a moving picture experts group transport stream (MPEG-TS) layer, and a lost packet number Nr and a packet loss rate Rr of a real-time transport protocol (RTP) layer respectively; and performing association analysis on the packet loss parameters of the MPEG-TS layer and the RTP layer to judge whether an IPTV service quality problem caused by media stream packet loss is caused by a failure of the video server or the IP network. By the method and the system, the source of the network failure can be effectively determined, and failure detection efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication testing, and relates to an IPTV network fault isolation method, in particular to a fault isolation method between a video server and an IP network in an IPTV network; at the same time, the invention also relates to a video server and an IP network fault isolation method in an IPTV network Fault isolation system for IP networks. Background technique [0002] In recent years, with the rapid development of IP networks and applications and the increasingly intensified competition in the communication market, major telecom and radio and television operators around the world are setting off an upsurge of "triple play" business development. On the one hand, telecom operators have entered the field of digital TV through IPTV technology; on the other hand, cable TV operators have also accelerated the two-way transformation of digital TV networks and the transmission of IP-based trunk program signals ...
