Embodiment Construction
[0040] The present invention is described in detail below in conjunction with accompanying drawing:
[0041] Such as figure 1 As shown, the visualization method for network traffic changes provided by the present invention includes the following steps:
[0042] S1, establishing a template model library, the template model library is composed of a plurality of template models; each template model is used to define the threshold value corresponding to different traffic types of a trunk link and the total bandwidth of the trunk link port; wherein , the traffic type includes the incoming or outgoing traffic of the device ports at both ends of the trunk link; the threshold value is set according to one of the following rules: rule 1, only specify the first highest threshold value; rule 2, only specify Low threshold value; rule 3, specify the first high threshold value and the second high threshold value, wherein, the second high threshold value is greater than the first high thres...

The invention provides a visualization method and a device of network flow change. The method comprises a first step of establishing a template model library, a second step of collecting a current flow value of a specified relay link discontinuously according to the preset time, a third step of calculating a relay arrow drawing location, a fourth step of obtaining a relay arrow drawing color, a fifth step of drawing a current-time relay arrow on the drawn specified relay link according to the relay arrow drawing location and the relay arrow drawing color, and a sixth step of using the position of a primary relay arrow on the specified relay link as an initial position for drawing a relay flow change area, wherein the position of the primary relay arrow is collected and formed in a former time point, using a new relay arrow which is drawn on the present moment on the specified relay link as an end position for drawing the relay flow change area, and a relay link between the initial position and the new relay arrow reflects situation changes of network flow. According to the visualization method and the device for the network flow change, flow information can be displayed visually and comprehensively, and therefore people can analyze the basic rules of network behavior change conveniently.
Description
technical field [0001] The invention belongs to the technical field of network traffic display, and in particular relates to a visualization method and equipment for network traffic changes. Background technique [0002] In recent years, with the rapid expansion of the number of network users and the diversification of network business types, network congestion has become increasingly prominent. Strengthening network management and improving the network operating environment have become urgent problems to be solved. [0003] One of the important prerequisites for solving the above problems is: to measure the network traffic, and then visually display the network traffic, so as to analyze the basic laws of network behavior changes. In the existing network traffic visualization method, the displayed network traffic graph only contains a few types of traffic information, such as: the size of the traffic, the direction of the traffic, and cannot intuitively and comprehensively d...
