Self-adaptation burst flow detection device and detection method thereof

Abstract

The invention discloses a self-adaptation burst flow detection device and a detection method thereof. The detection device is composed of three modules connected in sequence, and the three modules refer to the data collection module, the data processing and storing module and the flow detection module. The data collection module is used for collecting data transmission rate information in a network and providing the data transmission rate information for the data processing and storing module for processing and storing, and the data transmission rate information serves as the basis in the flow detection module for detecting burst flow. The detection method of the burst flow detection device includes the steps of respectively maintaining a storage window queue Q with the largest space length N and a detection threshold value variable theta used for detecting the burst flow and adjusted in a self-adaptation mode according to the historical and current transmission rate data of the network. Thus, the network load and the network status can be free from configuration by utilizing the two parameters, the two parameters can adapt to change of the current network and automatically generate self-adaptation detection threshold values, and therefore self-adaptation detection on the burst flow of the network can be achieved, and the self-adaptation burst flow detection device and the detection method can have excellent popularization and application prospects.

Description

technical field [0001] The invention relates to an adaptive burst flow detection device and a detection method thereof, belonging to the technical field of computer networks. Background technique [0002] With the development of computer networks, the transmission speed of network bandwidth and equipment is getting higher and higher. Therefore, the network transmission speed becomes faster and faster, so it seems that the load balancing technology shows its importance more and more. Generally speaking, load balancing technology can make the network work well. However, when a transmission failure event occurs, the network is likely to become congested, and even affect the normal operation of the entire network. The so-called emergency refers to a large number of events gathered in a certain dimension (including time, space, etc.). Burst traffic is always accompanied by potential problems in the system or network. Therefore, the burst traffic detection method is particular...
