Embodiment 1

[0045] Embodiment 1 of the present invention discloses information access method, please refer to figure 1 , the method includes the following steps:

[0046] S101: Receive an information access request from a terminal, where the information access request includes an information identifier of the requested target information.

[0047] Wherein, the information requested by the terminal may be various network information. In this embodiment, the method of the present invention is described by taking the request for streaming media content as an example. The information access request of the terminal includes the identifier of the requested streaming media content, for example, it may be a video name etc. The method of this embodiment utilizes HTTP (HTTP-Hypertext transfer protocol, hypertext transfer protocol) to access streaming media content through the network.

[0048]Wherein, the terminal may be a set-top box, a computer, or a mobile device such as a mobile phone or a ta...

Embodiment 2

[0063] This embodiment two continues to optimize the information access method of embodiment one, see figure 2 , the method also includes:

[0064] S106: If the information cached in the edge access server has not been requested for more than a preset period of time, issue a clearing instruction, the clearing instruction is used to clear the information cached in the edge access server, and clear the mapping The corresponding relationship between the information that has not been requested and the edge access server recorded in the relationship table.

[0065] In this embodiment, the survival period is set for each mapping relationship record in the mapping relationship table in real time, and whether the corresponding record should be cleared is determined according to the set time and the setting survival period.

[0066] Specifically, when receiving a request from a terminal, if the corresponding relationship between the requested streaming media content and the server is...

Embodiment 3

[0070] This embodiment three further optimizes the information access method disclosed in the above embodiments, please refer to image 3 , the method also includes:

[0071] S107: If the concurrent amount of information access requests received by the edge access server reaches a preset threshold, delete the server ID of the edge access server from the standby server ID set so as not to be used for the The edge access server allocates information for caching.

[0072] In practical applications, the distribution of users' access to streaming media content is often extremely unbalanced. The existing technology tries to ensure the balanced distribution of streaming media content on different edge access servers (that is, each server roughly caches the same amount of streaming media content). Load balancing of each edge access server, but this method is less effective and cannot achieve a higher degree of load balancing. Using this method, the same edge access server may be allo...

Abstract

The invention discloses a method and system for accessing information. The method includes the steps of caching the information in a data source according to the one-to-one mapping relation, caching same contents into certain edge accessing servers, and storing one-to-one mapping relations between the information contents and the edge accessing servers to form a mapping relation table; based on the mode, when accessing requests of terminals are received, if requested information contents are contained in the table, representing that requested target information is cached in the servers, and directly obtaining the servers where the target information is cached from the table; if the requested information contents are not contained in the table, calculating the edge accessing servers corresponding to the target information, caching the target information in the data source into the servers, and meanwhile adding mapping relations between the information and the servers into the mapping relation table; then responding to the terminals, and informing the terminals of the servers where the target information is cached to enable the terminals and the servers to be in communication to achieve information accessing. By means of the method and system, multiple copies of the same contents are avoided, and cache space is saved.

Description

technical field [0001] The invention belongs to the technical field of network information access and scheduling, and in particular relates to an information access method and system. Background technique [0002] With the rapid development of computer network and mobile Internet technology, people's demand for access to streaming media is increasing, and the access to streaming media content such as video accounts for an increasing proportion of Internet information access. [0003] In order to meet people's growing demand for access to streaming media, it is necessary to cache the streaming media content in the data source stored in the center to the edge access server cluster, and provide end users with streaming media storage through each edge access server included in the cluster. services to ease the pressure on the backbone network. At present, the streaming media content is generally cached in a one-to-many manner, that is, the same streaming media content in the da...
