Embodiment Construction

[0026] figure 1 It is a flow chart of the first embodiment of the method for content distribution of the present invention, the method of this embodiment includes:

[0027] S100: The cache server in the access network receives a service request sent by the user equipment, where the service request includes the address of the content server where the service data requested by the user equipment is located.

[0028] Specifically, for example, the service request may be a request for web services, such as accessing webpages, audio and video, etc., and of course it may also be other types of services, which are not limited in this embodiment of the present invention; the content server, for example , may be located in the Internet (Internet), and store service data that the user wants to access, and the address of the content server may be a public address (Public Address).

[0029] S101: If the service data requested by the user equipment is stored in the cache server in the acc...

Abstract

The embodiment of the invention relates to a content distribution method and device as well as access network equipment. The content distribution method of the embodiment of the invention comprises the following steps: a cache server in an access network receives a business request transmitted by user equipment, and the business request contains the address of a content server in which business data requested by the user equipment is located; if storing the business data requested by the user equipment, the cache server in the access network transmits the stored business data to the user equipment through the access network equipment, modifies the address of the content server in the received business request into the address of the cache server in the access network and transmits the address of the cache server to core network equipment; the cache server in the access network receives the modified business request which is routed to the cache server in the access network through the core network equipment; the stored business data is transmitted to the cache server in the access network through the internet, the core network equipment and the access network equipment; and the cache server in the access network discards the business data. The technical scheme of the embodiment of the invention can lead the core network equipment to be capable of controlling and managing the business data requested by the user equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a content distribution method, device and access network equipment. Background technique [0002] Content Delivery Network (CDN) is an application layer network architecture proposed to solve the current network congestion, broadband bottleneck and other problems. The content distribution network can quickly push the content accessed by users to the edge of the network, so that the user's request can be quickly responded to nearby, which not only greatly reduces the load of the network, but also reduces the probability of network congestion and shortens the request delay. To achieve this purpose, a cache (Cache) server may be used in the content delivery network. For example, the service request of the user equipment (User Equipment, UE) is first sent to the cache server in the access network, if the service data requested by the user equipment is stored in the cache server in ...
