Traffic behavior analysis method oriented to distributed network

A distributed network and network traffic technology, applied in the field of traffic behavior analysis for distributed networks, can solve the problem that it is difficult to describe the internal behavior status of network node traffic, the overall traffic behavior status of the entire network, and the difficulty of reflecting the overall behavior characteristics of the entire network. Issues such as gaining an understanding of overall network traffic behavior

Problems solved by technology

[0005] (1) In the traffic analysis method for a single point, only the traffic passing through the node can be obtained, and only local network traffic information can be analyzed, and it is difficult to obtain the understanding of the overall network traffic behavior, and network management cannot only rely on local information, Or only for local problems, it is necessary to formulate an overall optimal plan and strategy from a global perspective
[0006] (2) In the multi-point-oriented traffic analysis...

Embodiment

[0160] The embodiments illustrate the advantages of the method by taking the analysis of the data packet arrival pattern of the network nodes as an example. Such as Figure 6 As shown, the example network includes 50 network nodes and 88 links. The topology comes from a German research network (topology information of a German research network http: / / sndlib.zib.de / home.action), and different nodes in the jurisdiction network To capture traffic data, here the data packet arrival rate is used as the node observation value, and the node data packet arrival mode is the traffic behavior state. According to this distributed network traffic behavior analysis method, the data packet arrival mode of the whole network at different times and different regions is perceived, and the realization Monitoring of network-wide packet arrival patterns. According to the above implementation steps S1-S6, firstly, deploy the traffic collection scheme in the entire network; secondly, collect the his...

Abstract

The invention provides a traffic behavior analysis method oriented to a distributed network. The method comprises the following steps: deploying a network traffic collection scheme; collecting historic traffic data; training a model; acquiring a traffic behavior model; collecting real-time traffic data; and estimating the network global traffic behavior. The whole distributed network is regarded as the whole, the network traffic intrinsic behavior state is analyzed by collecting the network node traffic information and utilizing space-time context relation of the network node traffic behavior,the monitoring on the network global traffic behavior is realized, the resource scheduling, the abnormal detection and like network management work can be developed in assistance.

Description

technical field [0001] The invention relates to the application field of network management, and more specifically, relates to a flow behavior analysis method oriented to a distributed network. Background technique [0002] With the rapid development of network and information technology, the unprecedented expansion of network scale and the wide use of various network applications, the network is deeply integrated into the political, economic, cultural and other fields. At the same time, the complexity of the network increases the difficulty of network management and maintenance, making network administrators face many difficulties. The advancement of IPv6 technology promotes the transition of network protocols from IPv4 to IPv6, which often causes IPv4 / IPv6 dual-stack parallelism in the network, which increases the difficulty of troubleshooting network anomalies. Various networks, including wireless local area network, wireless metropolitan area network, and public mobile ...
