Request task scheduling method and scheduling centre server

Abstract

The invention discloses a request task scheduling method and a control centre server, wherein the method comprises the steps of: receiving node information reported by a CDN node to be scheduled, andconstructing multiple training samples based on the node information; creating a support vector machine model, wherein the support vector machine model comprises the specified number of binary classifiers; and furthermore, the specified number is determined based on the total number of CDN nodes to be scheduled; training the support vector machine model for several times by utilizing the constructed multiple training samples, wherein a corresponding weak classifier is generated after training for each time; and furthermore, the weak classifier has a weight value; and, on the basis of the weight values of various weak classifiers, combining the various weak classifiers into the final classifier, and scheduling received new request tasks in the CDN node to be scheduled through the final classifier. By means of the technical scheme provided by the invention, the request task scheduling precision can be increased.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a scheduling method for request tasks and a scheduling center server. Background technique [0002] With the continuous rise of the live broadcast industry, in order to provide users with a smooth video live broadcast experience, live broadcast service providers usually use a CDN (Content Delivery Network, content distribution network) to share the live stream and accelerate the live stream. [0003] At present, when the CDN control center receives a request task from a user for loading a live stream, it can determine the CDN suitable for processing the request task according to the load number and freeze rate of each CDN node in the current network. node, and schedule the request task to the determined CDN node. [0004] However, in the current scheduling method for request tasks, the basis for judging CDN nodes is too single, which may cause misjudgment, resulting in unev...

AI Technical Summary

Problems solved by technology

[0004] However, the current scheduling method for request tasks is based on a single judgment basis for CDN nodes, which may cause misjudgment, resulting in uneven distribution of request tasks

Once the judgment basis is added, the judgment process will be too complicated. At present, there is no suitable solution to deal with the complex judgment process.
