The embodiment of description.On the contrary, purpose of providing these embodiments is make it is more thorough and comprehensive to the disclosure.
Unless otherwise defined, all of technologies and scientific terms used here by the article and belong to the technical field of the present invention
The normally understood meaning of technical staff is identical.Used term is intended merely to description tool in the description of the invention herein
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the Listed Items of pass.
Currently, not become more and more by the transmission bandwidth of protocol integrated test system, in such a case, sent out according to Ethernet high speed
The requirement of exhibition needs to control transmission bandwidth, to reach transmission rate demands, just can avoid network congestion even packet loss
Problem occurs.
Band width control method provided in an embodiment of the present invention, can be applied in application environment as shown in Figure 1, and Fig. 1 is
The applied environment figure of band width control method one embodiment of the present invention.Wherein, terminal 102 is passed through by network and server 104
Network is communicated.102 measurement data packet length of terminal, real-time dynamic regulation bandwidth, with pre-set bandwidths transmission packet to net

The server cluster of a server composition is realized.
Specifically, an embodiment of the present invention provides a kind of band width control method, as shown in Fig. 2, Fig. 2 is bandwidth control of the present invention
The first pass schematic diagram of embodiment of the method 1 processed, including：
Step S210 measures the data packet length of data to be transmitted packet；
Specifically, the data to be transmitted packet to input carries out linear measure longimetry, data packet length can be obtained；Preferably, may be used
Transmission packet is treated using the clock cycle of work clock to be counted, obtained counting number can be data to be transmitted packet
Data packet length；Further, after obtaining data packet length, which can be recorded designated position；
It should be noted that data to be transmitted Bao Kewei prepares the data packet for being transmitted to Ethernet；
Data packet length can be measured or be calculated as unit of byte, such as the physical characteristic of Ethernet determines link
The maximum length of layer data frame is 1500 bytes, a longest IP packet may be 65535 bytes etc.；
Step S220 is based on data packet length and pre-set bandwidths, generates output proportioning and in transmission process
It is spaced the idle data packet of data to be transmitted packet；Output proportioning is the data packet length ratio of data to be transmitted packet and idle data packet
Or quantity ratio；
Specifically, by the data packet length of input, generates idle data packet according to pre-set bandwidths and output matches；
It should be noted that pre-set bandwidths can be used for according to actual needs, carrying out amount of bandwidth or rate being configured, it can
