Problems solved by technology

[0004] However, in the actual process, there will be the following problems: due to the different resource configurations of each central node, the maximum load that can be tolerated will vary
Repeating this process in this way will eventually lead to large fluctuations in the service quality of the CDN, and the performance is very unstable, which will affect the product reputation

Embodiment Construction

[0025] The application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiments of the present application describe a progressive traffic scheduling method and system for filtering jitter in a CDN environment. CDN (Content Distribution Network) is a new type of network construction method. It is a network coverage layer specially optimized for publishing broadband rich media content on traditional IP networks, so as to ensure that content can be requested by users in an extremely efficient manner. Provide services. Media content distributed in a CDN may include web objects (e.g., text, graphics, URLs, scripts), downloadable objects (e.g., media files, software, documents, etc.), web applications, streaming media (e.g., audio and video content), etc. Simply put, CDN is a strategically deployed overall system, including four elements: distributed storage, load balancing, redirection of network requests, and content man...

Abstract

The application provides a progressive flow scheduling method and system capable of filtering vibration. The method comprises the following steps that: S1, an edge service node sends a detection request to all central nodes regularly and each central node returns integrated load information, as a response, of current equipment to the edge service node; S2, after the edge service node receives the integrated load information of the central nodes, the central nodes are sorted in an ascending order according to round-trip time (RTT) of the central nodes, a load situation of each central node is determined according to the integrated load information of the central node to determine a flow scheduling strategy of each central node, and then a load threshold value of each central node is updated; and after the edge service node receives a request sent by a user, an IP of the central node that is going to send the request finally is queried based on the load threshold values of the central nodes, and the request is forwarded to the corresponding central node.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a progressive traffic scheduling method and system for filtering jitter. Background technique [0002] With the increasing amount of data transmission on the Internet, in order to avoid bottlenecks and links that may affect the speed and stability of data transmission on the Internet, and to make content transmission faster and more stable, a CDN ( ContentDeliveryNetwork, content distribution network) technology. In the technology, a layer of intelligent virtual network based on the existing Internet is formed by placing node servers all over the network to improve the response speed of the network. The network structure of a common intelligent virtual network has a two-layer structure of center-edge layer. The first layer is the edge service node, which is deployed in the network as close as possible to the user. The second layer is the central node, which is dep...
