Outburst convergence control method, and corresponding device and communication device

Abstract

The invention discloses a controlling method for a burst assembly, a corresponding device and a communication equipment thereof. A core of the method and the device in the invention includes the following steps: by comparing an assembly time with a time threshold set in advance, a change trend of carriers in a buffer queue is judged; if the change of the carrier burst is increased or reduced, a length threshold is directly increased or reduced; if the carriers are in an increasing trend, the threshold is randomly increased according to a certain probability; if the carriers are in a reducing trend, the threshold is randomly reduced according to a certain probability; if the carrier is normal, the length threshold is not adjusted, therefore, the length threshold can realize dynamic adjustment with the changes of the carrier. By adopting the method and the device provided by the invention, a delay from a business end to anther business end is assured, thus optimizing the performance of the network.

Description

technical field [0001] The present invention relates to communication technology, in particular to a burst aggregation control method, a corresponding device, and communication equipment. Background technique [0002] The rapid development of Internet services and the diversity and variability of emerging services (web page browsing, multimedia services, resource downloads, web conferencing, etc.) have made the traditional core switching network unsuitable for its continuous development. In this situation, in order to adapt to the explosive growth of Internet traffic, the increasing demand for bandwidth, and the diversity and burstiness of services, researchers have invested deeply in WDM or DWDM transmission. At present, dense wavelength division multiplexing technology can already make the transmission bandwidth reach about 10Tbit / s, which can meet the demand for transmission network bandwidth in a long period of time. Since network switching nodes need to convert the tra...

Problems solved by technology

In the long run, OPS is a promising technology, but it is currently facing some difficult problems: first, the optical switch technology that can effectively support OPS in the near future is immature, and at the same time, the switching speed of the optical switch matrix is ​​currently difficult to reach Second, it is quite difficult to synchronize packets at the entrance of the switch, which cannot effectively reduce the conflict between packets; finally, there is no real random storage mechanism in the optical domain, and the current optical domain cache can only rely on FDL ( Fiber Delay Lines), and the use of FDL is also limited by signal quality and physical space, which cannot provide enough flexibility and sufficient buffering

[0014] However, this burst aggregation method based on a fixed-length threshold still has the following disadvantages:

The way of judging the load adopted by this method cannot adapt well to the change of load.

[0020] Second, although this method proposes to change the aggregation length threshold as the load changes, it does not clearly point out what relationship the two should conform to to achieve mutual matching, that is to say, the purpose of self-adaptation is not clear

[0021] Third, although this method introduces the hysteresis change characteristic, the aggregation threshold can be changed after multiple comparisons to determine the load change, which can alleviate the continuous excessive change of the length threshold to a certain extent, but it also slows down the impact of the length threshold on sudden changes. The tracking ability of the hair, that is, the adaptive ability of the method is reduced
