A method for obtaining resources, a terminal and a server

Abstract

The invention provides a method for obtaining resources, a terminal and a server, relating to the field of communication, combining network topology and network quality information, and selecting an optimal cache server according to terminal information to realize resource acquisition. Including: requesting the scheduling server to receive the scheduling request information sent by the terminal; the scheduling request information includes terminal information; requesting the scheduling server to allocate N cache servers for the terminal according to the network topology information of the network, the network quality detection record set and the terminal information; N is an integer greater than or equal to 1; the request scheduling server sends cache server information to the terminal, and the cache server information includes addresses of N cache servers, and network quality information between each of the N cache servers and the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for acquiring resources, a terminal and a server. Background technique [0002] CDN (Content Delivery Network, Content Distribution Network) is a new layer of network architecture added to the existing Internet, and it is the "edge" of the network closest to users. Web content can be published to CDN, so that users can obtain the desired content from CDN nearby. In this way, the situation of Internet network congestion can be solved, and the service quality of services or services that users can obtain can be improved. [0003] The CDN deploys multiple different cache servers in different network locations, and multiple cache servers store content. After the terminal obtains the addresses of multiple cache servers, it can download content from multiple cache servers at the same time. [0004] In the prior art, when a user requests a cache server, he first sends a sche...

[0005] In fact, the address of the user is different from the address of the DNS server assigned to the user. The cache server assigned to the user based on the address of the DNS server may not be close to the network in distance, resulting in poor results for the user to obtain resources from the cache server.

At the same time, the existing technology configures the same DNS server for multiple users, so different users are assigned the same cache server because they correspond to the same DNS server

It is not possible to allocate cache servers based on users. Multiple users obtain resources from the same cache server, which may also affect the effect of resource acquisition.
