Abstract
The invention discloses a video storage system and a load balancing method thereof. Acquired video data is partitioned into data packets, and the data packets are sequentially stored in storage servers in a polling manner. As the partitioned data packets are identical in size, the size difference of stored data on the storage servers in each time is eliminated; as the data packets are sequentially and respectively stored in the multiple storage servers, the load balance of the storage servers is realized, the reliability of data storage is guaranteed, and the storage performance of a video storage system is optimized.
Description
Technical field
The present invention relates to the video storage technical field, particularly relate to the method for a kind of Video Storage System and load balancing thereof.
Background technology
Video Storage System generally comprises a forwarding server and Duo Tai storage server.Wherein, forwarding server is used for obtaining video file or the video data that records and being transmitted to certain storage server, and this storage server is received behind the video data its storage.
The video data of recording, what have is large, what have is little, when the video data that size is uneven is given different storage server storages, following phenomenon often occurs: a storage server is in busy condition, another storage server is in idle condition, and perhaps last memory space differs greatly between the storage server.The storage server that over-burden can produce obliterated data or read the situation of makeing mistakes, and is unfavorable for the reliability of Video Data Storage, has also reduced the memory property of Video Storage System.
Summary of the invention
Based on above-mentioned situation, the present invention proposes the method for a kind of Video Storage System and load balancing thereof, to realize the load balancing of each storage server.
A kind of method of Video Storage System load balancing comprises step:
Obtain video data to be stored;
Described video data is divided into a plurality of packets of specifying size;
Described packet is stored in each storage server successively according to the mode of poll.
A kind of Video Storage System comprises forwarding server and Duo Tai storage server,
Described forwarding server is used for obtaining video data to be stored, and described video data is divided into a plurality of packets of specifying size, and according to the mode of poll described packet is stored in each described storage server successively.
The method of Video Storage System of the present invention and load balancing thereof is divided into one by one packet with the video data that obtains, and the mode according to poll is stored in each storage server successively again.Because the data package size after cutting apart is consistent, therefore eliminate storage server and stored the difference of size of data at every turn, again because a plurality of packets are stored in respectively a plurality of storage servers in order, realized the load balancing of storage server, guarantee the reliability of data storages, optimized the memory property of Video Storage System.
Description of drawings
Fig. 1 is the schematic flow sheet of the method for Video Storage System load balancing of the present invention;
Fig. 2 is the structural representation of Video Storage System of the present invention.
Embodiment
The present invention is encapsulated as packet with video data, again packet is stored in each storage server successively, to reach the purpose of load balancing.Explain in detail the present invention below in conjunction with accompanying drawing and embodiment.
The method of Video Storage System load balancing of the present invention as shown in Figure 1, comprises step:
Step S101, obtain video data to be stored;
Step S102, described video data is divided into a plurality of packets of specifying size;
Step S103, described packet is stored in each storage server successively according to the mode of poll.
The reason of conventional store mode load imbalance is that video data is not of uniform size, therefore, after this method is obtained the video data that records, first video data is carried out dividing processing, be divided into several equal-sized packets, mode according to poll is stored in each storage server with these packets again, thereby realizes the load balancing of storage server.
For the ease of inquiry, can also record after video data cut apart under each described packet video data and corresponding under which bag of video data, with packet store finish after, the storage server of can also the record data bag storing.
Behind the Video Data Storage, the user may need reading video data, therefore, this method can also comprise step: after receiving reading order, inquire about described record, from the described storage server of correspondence, read described packet, the described packet that reads is packaged, be reduced to the transmit leg that returns to described reading order after the original video data.
Step S102 mentions, and the size of packet is appointment.When implementation this method, the size of packet is unsuitable excessive also unsuitable too small, and should adapt with following two factors: described video data is carried out the required cache-time of each described packet in the cutting procedure, described packet is stored in the fragment degree of described storage server behind the described storage server.When video data is divided into packet, need to will be distributed to storage server behind the data pack buffer, so packet is larger, cache-time is more of a specified duration, is unfavorable for improving storage efficiency again.And packet is too small, and with the workload that increase is cut apart, too small packet is kept in the storage server, will form one by one fragment, is unfavorable for reading.
As a preferred embodiment, this method also comprises step: the described storage server of opening is safeguarded a formation.When described packet is stored in described storage server, be stored in successively storage server in the described formation according to the mode of poll.
Video Storage System of the present invention as shown in Figure 2, comprises forwarding server and Duo Tai storage server, and forwarding server links to each other with many storage servers respectively.
Described forwarding server is used for obtaining video data to be stored, and described video data is divided into a plurality of packets of specifying size, and according to the mode of poll described packet is stored in each described storage server successively.
As a preferred embodiment, described forwarding server also is used for which bag of the video data under each described packet of record, corresponding affiliated video data and the storage server of storing, so that inquiry.
As a preferred embodiment, described forwarding server also is used for after receiving reading order, inquire about described record, from the described storage server of correspondence, read described packet, the described packet that reads is packaged, be reduced to the transmit leg that returns to described reading order after the original video data.
As a preferred embodiment, the size of the described packet that described forwarding server is cut apart and following two factors adapt: described video data is carried out the required cache-time of each described packet in the cutting procedure, described packet is stored in the fragment degree of described storage server behind the described storage server.
As a preferred embodiment, described storage server starts backward described forwarding server registration, described forwarding server is safeguarded a formation to the described storage server of opening, when described packet is stored in described storage server, be stored in successively storage server in the described formation according to the mode of poll.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
