Embodiment Construction

[0025] Please see figure 1 , figure 1 It is a schematic diagram of a node topology network structure according to an embodiment of the present invention. This embodiment takes the P2P live broadcast system as an example for illustration. In the P2P live broadcast system, there are various models of network topology, but the position of a node in the topology can be defined as follows: node T (Peer T) has n( n>=1) parent nodes provide data streams for node T, and at the same time provide data streams for m (m>=1) child nodes.

[0026] The types of QoS anomalies of node T include: uplink bandwidth anomalies, downlink bandwidth anomalies, and network anomalies. Uplink bandwidth anomalies may also be referred to as parent node anomalies, and downlink bandwidth anomalies may also be referred to as child node anomalies. Please refer to figure 2 , the QoS anomaly detection system 200 of the embodiment of the present invention includes: a receiving module 202 , a slice storage mod...

Abstract

The present invention provides a detection method of factors resulting in abnormal QoS, and comprises the following steps: receiving the point-to-point P2P data code flow which is sliced by the server; judging whether the data flow has the information of data loss according to the data code flow; and determining the factors resulting in the abnormal QoS according to the domain value parameters, if the data flow has the information of data loss. The method can accurately position the information head of abnormal QoS to the degress of domain; the factors resulting in the abnormal QoS can be accurately detected; the information of the abnormal QoS in the P2P system can be accurately detected, thus the QoS in the system can be really protected.

Description

technical field [0001] The present invention relates to QoS (Quality of Service, server quality) anomaly detection technology, in particular to a QoS anomaly detection method, system and device. Background technique [0002] With the development of science and technological progress, more and more media technologies have entered thousands of households. Among them, P2P (Peer to Peer, point-to-point) technology is a relatively widely used technology in streaming media live broadcast technology, and it has also become an industry research and development technology. the key of. [0003] In the traditional streaming media live broadcast system, the streaming media data of the client is provided in real time by the streaming media server (Media Server, MS). To impact, but also increased the load on the media server. Therefore, the performance and QoS of the media server become the bottleneck of the system. In order to solve the problems of media server performance and QoS, P2...
