Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended The example of device and method being described in detail in claims, some aspects of the invention are consistent.

Video monitoring system is divided into Intranet and outer net, Intranet include capture machine, Intranet bayonet server, intranet data storehouse and Intranet storage system；Outer net storage system includes outer net bayonet server, outer grid database and outer net storage system, which deposits Storage system and outer net storage system constitute the data-storage system in video monitoring system.Referring to Figure 1A, Intranet storage system It is all made of distributed structure/architecture with outer net storage system, is divided into management node and multiple memory nodes according to physical aspect.Each deposit Block device on storage node is divided into two parts, and a part is rolled up by cloud storage service as cloud storage come using a part passes through Carry local file system comes as FTP service using being specifically provided as FTP catalogue.

Specifically, referring to Figure 1B, which includes the first management node and multiple first memory nodes, each First memory node includes cloud storage volume and the FTP catalogue for supporting File Transfer Protocol FTP service；The outer net storage system includes Second management node and multiple second memory nodes, each second memory node include cloud storage volume and the FTP for supporting FTP service Catalogue；Operation has ftp client on the gateway.

In the following, being based on data storage procedure, the function of above-mentioned Intranet storage system, gateway and outer net storage system is carried out It introduces:

Intranet storage system: the first management node and multiple first memory nodes

First management node is for being managed the storage resource of multiple first memory nodes, each first memory node It is divided into cloud storage volume and FTP catalogue, the FTP catalogue refers to the FTP service of carry local file system.Each first storage Node corresponds to only one first node mark, and the first node mark of each first memory node is all different.

First management node of the Intranet storage system is used to receive the resource allocation request of capture machine, by multiple first The first memory node of target in memory node distributes to the capture machine；First memory node of target is for receiving the capture machine The multi-medium data of transmission and short Universally Unique Identifier UUID (Universally Unique Identifier, it is general unique Identification code) when, the multi-medium data and the short UUID are stored into the cloud storage volume of the first memory node of the target and be somebody's turn to do In the FTP catalogue of the first memory node of target.It should be noted that the first memory node of target can be synchronized multi-medium data It is written with the short UUID in the FTP catalogue of first memory node of target.

Wherein, first management node is for determining target first according to preset rules from multiple first memory node Memory node, and the first node of first memory node of target mark is sent to the capture machine, by capture machine by multimedia First memory node of target is written in data and the short UUID.First management node can be according to load balancing principle from multiple Determine that a present load meets the second memory node of demand as the first memory node of target in two memory nodes, certainly, Each first memory node can correspond to a cryptographic Hash range, which is also based on hash value algorithms The cryptographic Hash of multi-medium data is calculated, to select the first memory node of cryptographic Hash range corresponding to the cryptographic Hash as mesh the One memory node, how the embodiment of the present invention is to specifically selecting node without limitation.

Wherein, short UUID can be stored in more by memory node when being stored multi-medium data and short UUID correspondence In the data head of media data (as shown in Figure 1 C), corresponding short UUID is carried by multi-medium data, to incite somebody to action subsequent When multi-medium data is transmitted in outer net storage system, the UUID of multi-medium data is remained unchanged, and is allowed to directly according to short UUID determines same multi-medium data in Intranet storage system and outer net storage system, and upper layer application storage multimedia is omitted The mapping relations of physical address of the data in Intranet storage system and outer net storage system avoid occurring in upper layer application different Chang Shi, the mapping relations that may cause permanently are lost, and lead to not search in Intranet storage system and outer net storage system more Media data.

After storing multi-medium data and short UUID in the cloud storage volume to the first memory node of target, due to multimedia Data are stored on the memory node of Intranet, and therefore, multi-medium data can correspond to a physical address, the target in Intranet One memory node can store the mapping relations between physical address and short UUID.The first memory node of target can be generated Mapping table as shown in Table 1 stores the mapping relations between short UUID and physical address into mapping table.

Table 1

Short UUID	abc
		Physical address	def
Timestamp information	22:02:06
		Random code	123456

In order to which the information of more detailed data recording multimedia data and enhancing are to the confidentiality of multimedia messages, in reality In, the timestamp information and random code of multi-medium data can also be increased in mapping table.It should be noted that The mode of mapping relations is without specifically limiting between present invention UUID short to storage and physical address.The physics of multi-medium data The mapping relations of address and short UUID have also been made in the storage volume of the bottom of cloud storage system other than being stored in database Backup, is saved together with multi-medium data.It can also be restored by tool even if the map information of local data base loss, Improve Information Security.

It should be noted that the first memory node of target is when storing multi-medium data and short UUID to FTP catalogue, one Aspect can generate multi-medium data title for each multi-medium data, include short UUID in multi-medium data title, and will be more Media data is corresponding with multi-medium data title to be stored；It on the other hand, can be directly corresponding with short UUID by multi-medium data It is stored, the embodiment of the present invention is to this without specifically limiting.

In order to which the storage location of data recording multimedia data can directly exist when to inquire multi-medium data in Intranet Storage location obtains multi-medium data, which can be sent to the first management node for the short UUID；It should First management node is also used to the first node of the short UUID and first memory node of target mark being back to the capture machine, First virtual address is sent by the inside network interface card mouth server of the capture machine, and by the Intranet bayonet server by this first virtually Location is stored to intranet data storehouse, which is based on the short UUID and first node mark generates, so as to subsequent base Multi-medium data is obtained in the first virtual address.Wherein, virtual address can be URL ((Uniform Resource Locator, uniform resource locator) form.

In addition, the capture machine in Intranet is used to acquire the multi-medium data of its position, the short of multi-medium data is generated UUID, and based on the first memory node of target that the first management node is distributed, multi-medium data and short UUID are stored to interior The first memory node of target of net storage system, moreover, can be by first in the first virtual address for receiving multi-medium data Virtual address is uploaded to Intranet bayonet server；Wherein, multi-medium data can be image data or video data, each more matchmakers Volume data corresponds to the short UUID of only one, and the UUID of each multi-medium data is different.Short UUID is right with it for identifying The multi-medium data answered, capture machine can be generated using preset algorithm, be preset when generating short UUID for each multi-medium data Algorithm can be SHA1 (Secure Hash Algorithm, Secure Hash Algorithm) digest algorithm and Boost (portable) library Deng the present invention is to this without specifically limiting.

Intranet bayonet server is used to receive the first virtual address of capture machine transmission, and the first virtual address is transmitted to Intranet data storehouse is stored by intranet data storehouse；Intranet data storehouse is empty when receive Intranet bayonet server transport first Behind quasi- address, the first virtual address is stored.

Gateway

Gateway is used to read the multimedia number in the FTP catalogue of first memory node of target by the ftp client According to the short UUID, and the multi-medium data and the short UUID are sent to the second memory node of target of the outer net storage system FTP catalogue in；The gateway can be periodically detected each first memory node in Intranet storage system by ftp client FTP catalogue in whether be stored with new multi-medium data and short UUID, deposited when detecting in first memory node of target When containing new multi-medium data and the short UUID, more matchmakers in the FTP catalogue for reading first memory node of target are executed Volume data and the short UUID and the process sent to outer net storage system.

The target second that the gateway is also used to for the multi-medium data and the short UUID being sent to the outer net storage system is deposited It is after storing up in the FTP catalogue of node, the multi-medium data stored in the FTP catalogue of first memory node of target is short with this UUID is deleted, it is possible to reduce the data volume stored in Intranet storage system mitigates the pressure of Intranet storage system.

It should be noted that since the ftp client in gateway may manage multiple Intranet storage systems and outer net is deposited Storage system avoids multi-medium data and short UUID for the corresponding relationship established between Intranet FTP service and outer net FTP service The situation of data connection object mistake occurs when being transmitted, it therefore, can be by the of Intranet FTP service in ftp client One address of service is corresponding with the second service address of outer net FTP service to be stored.In this way, gateway before being worked, needs The first service address of the Intranet FTP service of Intranet storage system is obtained, the outer net FTP service of outer net storage system is obtained Second service address, and by first service address and second service address correspondence store the ftp client into gateway, so as to It is subsequent when multi-medium data and short UUID are transmitted to outer net storage system, it can determine outer net corresponding with Intranet storage system Storage system avoids connection object that mistake occurs.

Correspondingly, in embodiments of the present invention, due to being stored with first service address and second service in ftp client Corresponding relationship between location, therefore, after ftp client obtains multi-medium data and short UUID in Intranet FTP service, FTP Client can determine corresponding second service address according to the first service address of Intranet storage system, and by multimedia Data and short UUID are transmitted in the outer net storage system of second service address instruction.

Outer net storage system: the second management node and multiple second memory nodes

Second management node is for being managed the storage resource of multiple second memory nodes, each second memory node It is divided into cloud storage volume and FTP catalogue, the FTP catalogue refers to the FTP service of carry local file system.Each second storage Node corresponds to only one second node mark, and the second node mark of each second memory node is all different.

For any one second memory node, which is used for the FTP mesh in second memory node When receiving multi-medium data and UUID of gateway transmission in record, by the multi-medium data and the short UUID store to this second In the cloud storage volume of memory node.It should be noted that due to the second memory node by multi-medium data and short UUID storage When to FTP catalogue, on the one hand, multi-medium data title can be generated for each multi-medium data, wrapped in multi-medium data title Include short UUID, and store multi-medium data is corresponding with multi-medium data title；It on the other hand, can be directly by multimedia number It is stored according to corresponding with short UUID, therefore, if multi-medium data and multimedia number that the FTP catalogue of the first memory node stores According to title, then store multi-medium data is corresponding with multi-medium data title；If the FTP catalogue of the first memory node stores Multi-medium data and short UUID, then store multi-medium data is corresponding with short UUID.

In embodiments of the present invention, since the FTP catalogue of the second memory node stores the multimedia of gateway transmission first Data and short UUID, therefore, when increasing newly in Intranet storage system has multi-medium data and short UUID, in outer net storage system Also multi-medium data and short UUID can be increased newly.For the second memory node of each of outer net storage system, this second Memory node can periodically detect newly-increased multi-medium data and short UUID whether are stored in FTP catalogue, and work as and detect When FTP catalogue is stored with newly-increased multi-medium data and short UUID, newly-increased multi-medium data and short UUID are obtained, so as to will be new The multi-medium data of increasing and short UUID are stored to cloud storage and are rolled up, and complete multi-medium data and short UUID by Intranet storage system to outer The transmission of net storage system.After storing multi-medium data and short UUID into outer net storage system, can also be formed with it is interior Mapping relations in net storage system similarly, are no longer repeated herein.

Further, which identifies according to the second node of the short UUID and second memory node, raw The second management node, second pipe are sent at the second virtual address of the multi-medium data, and by second virtual address Manage node will second virtual address transmission outer net bayonet server, by the outer net bayonet server by second virtual address It stores to outer grid database.
