Embodiment approach 1

[0059] Embodiment 1. For any target edge process in the target edge process group corresponding to the target channel, when the bandwidth data of the target channel is not collected from the target edge process in the previous decision-making cycle, the edge proxy device will and the central decision task threshold to generate the bandwidth control threshold for the target edge process. When the bandwidth data of the target channel is collected from the target edge process in the last decision cycle, the edge proxy device will use the process group anti-burst ratio, the central decision task threshold, the target edge process and the target edge process group in the last decision cycle The collected bandwidth data of the target channel generates the bandwidth control threshold of the target edge process.

[0060] Specifically, when the bandwidth data of the target channel was not collected from the target edge process in the last decision cycle, it means that the target edge p...

Embodiment approach 2

[0067] Embodiment 2: For any target edge process in the target edge process group corresponding to the target channel, the edge proxy device generates the bandwidth control threshold of the target edge process according to the process burst prevention ratio and the central decision task threshold.

[0068] In specific implementation, the product of the process burst prevention ratio and the central decision task threshold is used as the bandwidth control threshold of the target edge process, specifically as shown in the above formula (1).

[0069] In the embodiment of the present application, the bandwidth control threshold of the target edge process is determined based on the bandwidth configuration information, so as to avoid the sudden increase of the bandwidth of the edge process from scratch.

[0070] On the basis of any one of the above two implementations, the edge proxy device sends the bandwidth control threshold of the target edge process to the target edge process in...

Abstract

The embodiment of the invention provides a bandwidth control method and device, and relates to the technical field of computers, and the method comprises the steps that edge proxy equipment obtains bandwidth configuration information and bandwidth data of a target channel in a previous decision period; and when it is determined that the decision center device does not generate the center control strategy of the target channel, generating an edge control strategy of the target channel according to the bandwidth configuration information and the bandwidth data of the target channel in the previous decision period, and then sending the edge control strategy of the target channel to the edge resource device. Because the edge proxy device generates the edge control strategy and issues the edgecontrol strategy to the edge resource device when the decision center device does not generate the center control strategy, the method for issuing the edge control strategy before the bandwidth valueof the client channel does not reach the control threshold can effectively solve the problem of center decision hysteresis. Therefore, the sudden increase of the bandwidth is avoided, and the CDN platform and the service of each client can be effectively protected.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a bandwidth control method and device. Background technique [0002] More and more Internet service providers deliver digital content to clients all over the world through a CDN (Content Delivery Network, content distribution network). The rapidly increasing bandwidth of customers in various industries will undoubtedly bring huge bandwidth pressure to CDN and a series of problems, such as how to maximize the use of CDN bandwidth resources and how to reasonably allocate bandwidth for each customer. The above problems require the CDN to have certain self-protection capabilities, and it is necessary to carry out adaptive control when the above problems occur, so as to prevent other customers from being affected or to minimize the number of affected customers. [0003] At present, when central decision-making is used to control edge resource devices,...
