Embodiment Construction

[0042] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0043] The figure is a flowchart of a method for distributing shaping tokens to each data stream in the present invention, wherein the main implementation process is:

[0044] Step S100, setting the shaping rate of the spare flow to a maximum value, and converting the shaping rate of the spare flow into a weight;

[0045] Step S101, judging whether all data streams in the system have been configured, if all configured, execute step S105, otherwise execute step S102;

[0046] Step S102, configuring a shaping rate of a data stream, and converting the shaping rate into a shaping weight;

[0047] Step S103, adding the data stream to the weighted fair queuing (WFQ, Weighted Fair Queuing) token distribution module according to the weight of the data stream;

[0048] Step S104, subtract the newly configured data flow shaping weight from the...

Abstract

The invention discloses a method for realizing addition of a traffic shaping token, which comprises the following steps: A. allocating a shaping rate to each data stream, converting the shaping rate to a shaping weight, and adding each data stream to a weighted fair queuing (WFQ) token distribution module according to the shaping weight of each data stream; and at the same time of performing step A, calculating the latest idle stream weight; B, according to the idle stream weight, adding the idle stream to the WFQ token distribution module; and C, adding a token to each data stream or idle stream by the WFQ token distribution module according to set intervals. The invention also discloses a corresponding device and a corresponding system. The method, the device and the system add tokens to each data stream and idle stream in a mode of allocating corresponding shaping rates and shaping weights to different data streams so as to realize the shaping of various data streams and achieve good effect.

Description

technical field [0001] The invention belongs to the field of data communication, and in particular relates to a method, device and system for implementing traffic shaping token addition. Background technique [0002] With the development of the network, the transmission mode of the shared medium has become the mainstream of the network. Due to its statistical multiplexing properties, network technologies for shared media are less costly. However, when it is hoped that these shared medium transmission methods can provide the same service level as the old-fashioned Time Division Multiplex (TDM, Time Division Multiplex and Multiplexer) network, many difficulties will be faced. The service level of a connection can be defined from three aspects: the validity of the connection, the delay of the connection, and the bandwidth of the connection; these three aspects determine the quality of a service. In general, routing and switching play a more important role in the availability ...
