Description

Database update method and dispatch server

The present application claims priority to Chinese Patent Application No. 201610500354.1, entitled "A Database Update Method, Apparatus and System", filed on June 29, 2016, the entire contents of which are incorporated by reference. Combined in this application.

Technical field

The present application relates to the field of communications technologies, and in particular, to a method for updating a database and a scheduling server.

Background technique

In the era of information resources explosion, the growth of multimedia information has grown exponentially. The storage of multimedia information has become a hot issue of increasing concern. At this point, the Content Delivery Network (CDN) came into being. By adding a new layer of network architecture to the existing Internet (Internet), the content of the website is published to the "edge" of the network closest to the user, and the user request is directed to the nearest service node to solve the Internet (Internet) network congestion. Status, improving the responsiveness of users to the website. Technically comprehensively solve the root cause of slow response time of users visiting websites due to small network bandwidth, large user access, and uneven distribution of network points. Although the content distribution network CND improves the problem of small network bandwidth and large user access to a certain extent, the connection interface of each content distribution network CDN is still limited.

In the prior art, the content distribution network CDN sends a connection between the CDN and the user equipment UE to the scheduling server (Global Server Load Balance, GSLB) every ten seconds, that is, the connection situation includes the number of connection interfaces used by the content distribution network CDN. The value and the number of remaining connection interfaces. When the user equipment sends a connection request for downloading multimedia information to the scheduling server, the scheduling server may determine, according to the connection situation sent by the content distribution network CDN, which user distribution network CDN establishes a connection with the content distribution network CDN.

Assuming that the maximum connection interface of the content distribution network CDN is 1000, the content distribution network CDN The scheduling server reports the connection status, that is, the number of used connection interfaces is 900, and the number of remaining connection interfaces is 100. The scheduling server allocates 100 connection interfaces available to the content distribution network CDN to the user equipment according to the connection request sent by the user equipment, and the user equipment implements the connection with the content distribution network CDN through the allocated connection interface. If the period of the connection situation is not reported to the content distribution network CDN at this time, the scheduling server still considers that the number of connection interfaces remaining in the content distribution network CDN is 100. The inventor has found that since the connection request sent by the user equipment to download the multimedia is a random event, it is possible that the number of connection requests for downloading multimedia received by the scheduling server suddenly increases. If the user equipment sends a connection request to the dispatch server again at this time, the dispatch server may still allocate the connection interface of the content distribution network CDN to the user equipment. However, the content distribution network CDN actually has no assignable connection interface for the newly connected user equipment to connect, and obviously such a scheduling method is obviously unreasonable.

In summary, the content distribution network CDN periodically reports the connection status of the content distribution network CDN to the scheduling server GSLB. However, the update mode will result in the connection status of the content distribution network CDN and the content distribution network learned by the scheduling server GSLB. The actual connection of the CDN does not match, causing the scheduling to fail. If the reporting period of the content distribution network CDN is shortened, the load of the content distribution network CDN is too large, which affects the playback quality of the connected user equipment on the content distribution network CDN.

Summary of the invention

The application provides a database update method and a scheduling server, which are used to ensure that the interface information of the content server stored in the database in the scheduling server and the interface of the content server are actual without changing the reporting period of the content server. The connection situation is consistent, which improves the scheduling efficiency of the scheduling server.
