Embodiment 1

[0027] The present invention discloses a high-performance IP media stream monitoring method. For the media stream on a single high-load Ethernet link, different media streams are distributed to multiple CPUs for multi-threading according to the key fields of the IP protocol through the Hash algorithm. KPI statistical processing, and then combine the KPI data generated by each CPU to form a KPI statistical result for all media streams of the entire link.

[0028] see figure 1 , the method includes the steps of:

[0029] [Step S1 ] Capture raw data of all IP media streams on an Ethernet interface through the collection device, and send the raw data to the first processing unit (eg, CPU_1). In this embodiment, the collection device is a network card.

[0030] [Step S2] carry out protocol decoding analysis and key field extraction on the captured IP media stream by the first processing unit; then perform operations (such as efficient mathematical operations) on the key fields of...

Abstract

The invention discloses a method and a system for monitoring high-performance IP (Internet Protocol) media stream. The method comprises the following steps of: for the media streams on a high-load Ethernet link, according to an IP key field, allocating different media streams to a plurality of CPUs (Central Processing Units) by a Hash algorithm to perform multi-thread KPI (Key Performance Indicator) statistics; and then, combining the KPI data generated by each CPU, thereby forming the KPI statistic result of all the media streams on the whole link. The method and the system can execute real-time VoIP (Voice over Internet Protocol) and IPTV (Internet Protocol Television) media stream quality of service (QoS) and quality of experience (QoE) parameter statistics on a Gigabit/10 Gigabit Ethernet interface, thereby reducing the cost of the monitoring system.

Description

technical field [0001] The invention belongs to the technical field of communication testing, and relates to a high-performance IP media stream monitoring method, in particular to a method for realizing real-time audio and video media stream monitoring on IP network links with high traffic load; meanwhile, the invention also relates to a method A high-performance IP media stream monitoring system. 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 operators around the world are setting off an upsurge of IPTV network construction and triple play business development. With the rapid development of domestic IPTV services and the continuous increase in the number of users, the export of IPTV platforms and the backbone links of IP core networks have widely used 10 Gigabit (10G) Ethernet technology. In addition, as unicast services such as...
