Data access request processing method and device, edge node server and edge cluster

Abstract

A data access request processing method and device, an edge node server and an edge cluster are disclosed. The method comprises the following steps: when a resource file access request of a client end is monitored via a first port, and an edge node server where the resource file being requested exists is determined via a first preset load equalizer according to a first buffer memory mapping relation; when that the source file being requested does not exist in the determined edge node server is determined, the resource file access request of the client end is sent to a second preset port; when the resource file access request of the client end is monitored via the second port, the edge node server where the resource file being requested exists is determined via a second preset load equalizer according to second preset buffer memory mapping relation. According to the above solution, the resource file access request of the client end can be accurately dispatched to a corresponding edge node server when the edge cluster is subjected to capacity expanding operation, and user experience can be improved.

Description

technical field [0001] The present invention relates to the field of content distribution network, in particular to a data access request processing method and device, an edge node server and a cluster. Background technique [0002] Content Delivery Network (ContentDeliveryNetwork, CDN), by placing node servers all over the network, builds a layer of intelligent virtual network on the basis of the existing Internet, and publishes the content of the website to the "edge" of the network closest to the user, so that the user The required content can be obtained nearby to relieve network congestion and improve the response speed of the website. Technically, it fully solves the problem of slow response speed of users visiting websites due to reasons such as small network bandwidth, large number of user visits, and uneven distribution of outlets. [0003] An edge cluster is a service cluster composed of multiple edge nodes and load balancers. Among them, the edge node is respons...

[0005] However, in the process of expanding the capacity of the edge cluster, the cache mapping relationship between all cached resource files and each edge node server in the edge cluster will change. When receiving the resource file access request sent by the client, As a result, the load balancer dispatches the request to an edge node server that does not have a corresponding resource file, which affects the normal operation of the edge cluster and reduces the user experience
