Method, device and system for distributing infrastructures

Abstract

The embodiment of the invention discloses a method, device and system for distributing infrastructures. The method includes the steps that a response to an infrastructure distribution record corresponding to a non-cached target domain name is generated when a local domain name server receives a domain name resolution request of a target domain name, a server for network services selects the infrastructures according to the received domain name resolution request, an infrastructure distribution record corresponding to the target domain name is generated according to a selection result and sent to the local domain name server, then the local domain name server caches the record and sends the record to a client side; a response to an infrastructure record corresponding to cached domain names is generated when the local domain name server receives the domain name resolution request, the record is read from a cache by the local domain name server and sent to the client side. According to the method, device and system for distributing the infrastructures, the infrastructure selection result is sent through a DNS transmission mechanism, the processing loads of the server for the network services on the infrastructure distribution requests are greatly reduced, and therefore large-scale inquiry access can be supported.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for allocating infrastructure. Background technique [0002] At present, when network services construct application layer data transmission services (such as online video services, file download services, etc.), they usually use multiple infrastructures with the same or similar functions to choose from. Data transfer between servers. Wherein, the infrastructure used by the network service may include, for example, a content delivery network (CDN), a P2P network, a data center network, and the like. [0003] Since the network service has multiple infrastructure options when providing data transmission services to users, and the performance and charging prices that different infrastructures can provide for users in different regions are usually different, therefore, when providing data transmission services to users When serving, network...
