Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 , figure 2 As shown, the software-defined network-based traffic monitoring system provided by the present invention includes: several network devices with port mirroring functions, collectors and controllers.

[0033] The network in the present invention is divided into a control layer and a basic equipment layer by adopting a software-defined network method, and several network devices with port mirroring functions are arranged on the basic device layer, and these network devices only have a simple data forwarding function. The collector and controller are set at the control layer. The controller contains a complete routing table and forwarding table for managing and configuring the network and deploying protocols. The control layer and the basic equipment layer use an open unified interface to interact.

[0034] In this embodiment, the ne...

Abstract

The invention discloses a flow monitoring system based on the software definition network and a flow monitoring method. The flow monitoring method comprises steps that, the software definition network method is employed to divide the network into a control layer and a basic equipment layer, the control layer is provided with a controller, has a complete routing table and a forwarding table and is used for managing and configuring networks and deploying protocols, the basic equipment layer only has a simple data forwarding function, flows of multiple monitored ports of the network equipment in the basic equipment layer are copied to a mirror image port of the network equipment, a data packet is acquired through the mirror image port, flow analysis is further carried out, and configuration and setting for the network equipment are correspondingly carried out through the controller according to the flow analysis result. According to the flow monitoring method, the mirror image port of the network equipment is utilized as an acquisition port, direct interconnection between the mirror image port and the acquisition device port is realized, data transmission time delay is greatly reduced, and data transmission performance and time are improved.

Description

technical field [0001] The invention relates to network monitoring, in particular to a software-defined network-based flow monitoring system and method. Background technique [0002] Nowadays, with the rapid expansion of network scale and speed, various P2P applications such as P2P downloads and network streaming online video occupy a large amount of bandwidth resources, leading to increasingly serious congestion problems. If there is a lack of control and effective management, valuable bandwidth resources are often occupied by malicious and non-critical applications, resulting in the failure of normal network applications for most users. Therefore, network traffic monitoring is imminent. [0003] Traditional network traffic monitoring technologies mainly include sFlow and Netflow: [0004] sFlow adopts data flow random sampling technology, which can provide complete flow information from the second layer to the fourth layer, and even the entire network, and can adapt to t...
