Problems solved by technology

The problem existing in the prior art is that the DNS can only obtain the IP address of the user's local DNS but cannot obtain the user's IP address, and it cannot guarantee that the local DNS configured by the user is correct and reasonable, so the local DNS configured by the user is incorrect. Unable to perform precise scheduling when
There are also problems in the existing technology. The central dispatcher adopts 302 dispatching with one more 302 jump, the processing time becomes longer, and the user delay is increased. At the same time, due to the addition of the central dispatcher, the corresponding cost also increases, such as the need to maintain the central dispatcher Wait

Abstract

The invention provides a large-scale cluster task scheduling method, a large-scale cluster task scheduling system and a CDN node. The method comprises the following steps: a client sends a (domain name system) DNS query request to a DNS; the DNS performs scheduling according to local DNS configuration of the client and returns specified content delivery network (CDN) node information to the client; the client is accessed to a specified CDN node according to the specified CDN node information; the specified CDN node judges whether the access request of the client belongs to the service of the node according to an address of the client; and the specified CDN node schedules the client to a CDN node to which the client belongs through temporary jumping according to the address of the client and a preset scheduling strategy if the access request of the client does not belong to the service of the node through judgment. According to the method provided by the embodiment of the invention, precise scheduling can be achieved, a judging step is added at the CDN node, no central scheduling machine needs to be added, and cost brought by a central scheduling machine can be saved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a large-scale cluster task scheduling method, system and CDN node. Background technique [0002] Such as figure 1 As shown, the prior art CDN (Content Delivery Network, content distribution network) adopts DNS (Domain Name System or Domain Name Service, Computer Domain Name System) scheduling during global load balancing, that is, through the IP address of the user's local DNS attribution, Assign it to a specific CDN node. The problem existing in the prior art is that the DNS can only obtain the IP address of the user's local DNS but cannot obtain the user's IP address, and it cannot guarantee that the local DNS configured by the user is correct and reasonable. Therefore, the local DNS configured by the user is incorrect. It is not possible to perform precise scheduling. [0003] In order to solve the above-mentioned problem that DNS cannot perform precise scheduling, suc...
