Method, device and equipment for adjusting CDN coverage scheme

Abstract

The invention discloses a CDN (Content Delivery Network) coverage scheme adjusting method, device and equipment, and the method comprises the steps: initializing an initial coverage scheme of a CDN; constructing at least two initial populations respectively comprising one initial coverage scheme; newly establishing a process/thread/coroutine for each initial population; in each process/thread/coroutine, based on the goal of reducing the coverage cost, an evolution operation is executed on an initial coverage scheme in one initial population to obtain a filial generation population corresponding to each initial population, and the filial generation population comprises candidate coverage schemes obtained by executing the evolution operation; and selecting a candidate coverage scheme with the lowest coverage cost from all the candidate coverage schemes as a target coverage scheme of the CDN. According to the technical scheme provided by the invention, the coverage cost of the CDN coverage scheme can be saved, and the adjustment difficulty and labor cost of the coverage scheme are reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method, device and equipment for adjusting a CDN coverage scheme. Background technique [0002] In the content delivery network (Content Delivery Network, CDN) technology, it can be realized between the service provider and the consumer, by setting up nodes or service clusters, so that users can obtain the required content nearby, so as to alleviate network congestion and improve The purpose of user access to website response speed. [0003] Further, using a set of service clusters to provide services to customers is also referred to as the customer's coverage resources. A customer needs to be served by a group of service clusters, and a service cluster can also provide services for multiple customers. Since the billing coefficients of the nodes / Internet access points (point of presence, POP) to which the service cluster belongs are different, when there are multiple can...

This method is inefficient, and only a few attempts can be made within limited energy and time;

[0006] 2) Try using a correlation search algorithm. Since this problem belongs to the category of non-deterministic Polynomial (NP) problems, ordinary exhaustive search has high time complexity, and general heuristic methods are difficult to design better The heuristic function to achieve the optimal solution
