Problems solved by technology

However, since users have different requirements for multimedia content, at the initial stage of the content server's start-up operation, when the assigned content server handles download requests for various multimedia content, it may be that it does not have the requested multimedia content itself. content, it is necessary to read the multimedia content from the back-source address of the multimedia content, and then provide it to the client that sends the download request, and there is a problem of low multimedia content cache hit rate
On the other hand, after a period of actual operation, the content server serving users in the same geographical area may actually store various and large amounts of multimedia content, from various TV drama series, movies to variety show content. Some multimedia content is actually not requested to be downloaded frequently, and the utilization rate of cached data is low.

Embodiment 1

[0037] Figure 4 It is a flowchart showing a method for scheduling a resource request according to the first exemplary embodiment of the present invention. In the dispatch server 150 as previously described or as Figure 5 The method of this embodiment is executed in the resource request scheduling apparatus shown in.

[0038] Reference Figure 4 In step S410, a resource request for multimedia content sent from the client is obtained.

[0039] For example, a request for downloading and playing "The First Episode of Langya List" sent by the application client of the wireless communication terminal 110 is acquired.

[0040] In step S420, a first mapping reference value of the multimedia content is calculated according to the information of the multimedia content.

[0041] Preferably, the first mapping reference value of the multimedia content is calculated according to the consistent hash algorithm and the information of the multimedia content.

[0042] In step S430, the second mapping ...

Embodiment 2

[0053] Figure 5 It is a logical block diagram showing a resource request scheduling device according to the second exemplary embodiment of the present invention.

[0054] Reference Figure 5 The device for scheduling resource requests in the second embodiment includes a resource request obtaining unit 510, a content mapping reference value calculating unit 520, a server mapping reference value obtaining unit 530, a content server selecting unit 540, and a content server allocating unit 550.

[0055] The resource request acquiring unit 510 is configured to acquire a resource request for multimedia content sent from the client.

[0056] The content mapping reference value calculation unit 520 is configured to calculate the first mapping reference value of the multimedia content according to the information of the multimedia content.

[0057] Specifically, the content mapping reference value calculation unit 520 is configured to calculate the first mapping reference value of the multim...

Abstract

The invention provides a scheduling method and a scheduling device of a resource request. The scheduling method is characterized in that a resource request of multimedia content sent by a client is acquired; the first mapping reference value of the multimedia content is calculated according to the multimedia content information; second mapping reference values of a plurality of content servers are respectively acquired; the content server having the second mapping reference value matched with the first mapping reference value is selected; and the selected content server is allocated to the client. Dynamic partition or grouping management and supply of a plurality of resources are carried out logically, and then during the operation process of the system, any content server focuses on the supply of the mapped resources, and therefore the cache hit ratios of the resources (for example the multimedia content) are increased.

Description

Technical field [0001] The present invention relates to information processing technology, in particular to a scheduling method and scheduling device for resource requests. Background technique [0002] In a content distribution network (CDN), when the server receives a download request from a content playback client for multimedia content for offline storage or online viewing, the server needs to allocate content for the download request of the content playback client The server then sends the download address including the address of the allocated content server (such as the CDN node server) to the content playback client. After that, the content playback client continuously downloads fragments of the multimedia content according to the download address for buffer playback or storage in a storage medium. [0003] In the existing content server scheduling technology, most of the content servers used to download the requested multimedia content are allocated to the user (the conte...
