According to the invention, the process for executing the back-source treatment for the video request is selected, so that the problems of reduction of treating speed of a process for a back source caused by overlarge load of local process and reduction of transmission speed of streaming media service video caused by reduction of treating capacity for multiple merging back sources are solved.
Description
Technical field
The present invention relates to communication technology neck rate, more particularly, to the source that the merges back into method and apparatus of a kind of streaming media service multi-process.
Background technology
Streaming media service refers to utilize the Internet and stream media technology to carry out live, and video, because having merged the abundant elements such as image, word, sound, excellent both in sound and shape, excellent, is increasingly becoming the main flow expression way of the Internet.Content distributing network (ContentDeliveryNetwork, CDN) in, multiple equipment are connected with node server, node server receives the content requests carrying the content identification of content provider network side from equipment, from content requests, parse content identification, and call time source address returning source address query interface inquiry content of content provider network according to content identification；Source operation is performed back according to returning source address.
In prior art, the process that Hui Yuan enters in a device is arbitrary or specifies, and Partial Process load can be made excessive, makes process reduce the processing speed of Hui Yuan, to multiple and beam back source disposal ability decline, cause the problem that streaming media service transmission of video speed reduces.
Summary of the invention
It is an object of the invention to provide a kind of new solution for streaming media service.Carry out in a device for solving streaming media service the process of Hui Yuan be any or specify cause a large amount of streaming media service can concentrate when going back to source entering some process and carry out Hui Yuan and make the excessive technical problem causing back source processing speed reduction of this process load.
According to the first aspect of the invention, it is provided that a kind of source that the merges back into method of streaming media service multi-process, wherein, multiple processes run on an equipment, said method comprising the steps of acquisition streaming media service request；Described streaming media service request is processed by a process in the plurality of process；Determine that mechanism determines the process number pro_i that time source of execution described streaming media service request processes in the plurality of process according to returning originating process.
Further, the process corresponding to described process number pro_i described streaming media service request is carried out back source to operate.
Described time originating process determines that mechanism includes that complementation calculates.
Described time originating process determines that the Hash calculation result of the stream ID that mechanism utilizes described streaming media service to ask carries out complementation and obtains performing described returning the process number pro_i that source processes number of processes.
Each of the plurality of process is for monitoring port numbers port_i of predetermined one or more stream media protocols acquiescence.
Port number according to stream media protocol acquiescence sets described number of processes.
The process being monitored by port numbers port_i of the stream media protocol acquiescence corresponding to described streaming media service request processes described streaming media service request.
According to the second aspect of the invention, it is provided that a kind of streaming media service multi-process merge back into source device, described equipment includes: acquisition module, is used for obtaining streaming media service request；And multiple process processing module, for running multiple process, including: the first process processing module, for processing described streaming media service request, and determine that mechanism determines the process number pro_i returning source process of execution described streaming media service request in the plurality of process processing module according to time originating process.
Further, described equipment also includes: the second process processing module, with determined by perform described streaming media service request return source process process number pro_i corresponding, for perform described streaming media service request return source process.
Described time originating process determines that mechanism includes that complementation calculates.
Described time originating process determines that the Hash calculation result of the stream ID that mechanism utilizes described streaming media service to ask carries out complementation and obtains performing described returning the process number pro_i that source processes number of processes.
Each of the plurality of process processing module is for monitoring port numbers port_i of predetermined one or more stream media protocols acquiescence.
Also include number of processes setting module, for setting described number of processes according to the port number of stream media protocol acquiescence.
The process being monitored by port numbers port_i of the stream media protocol acquiescence corresponding to described streaming media service request processes described streaming media service request.
The inventors found that, in the prior art, the process that source of returning during streaming media service enters is arbitrary, equipment can not set the process number returning source process performing described streaming media service request, Partial Process load can be made excessive, make process that the processing speed of Hui Yuan to be reduced, to multiple and beam back the disposal ability in source and decline, so that transmission of video speed reduces.Therefore, using the source that the merges back into method that the present invention provides, equipment is by setting different time source treatment progress number to different Streaming Media requests, it is possible to achieve load balancing between process in equipment, thus improves and beam back the disposal ability in source, improves transmission of video speed.By detailed description to the exemplary embodiment of the present invention referring to the drawings, the further feature of the present invention and advantage thereof will be made apparent from.
