Embodiment
Consulting shown in Fig. 1, is the applied environment figure of memory space expanding system 100 preferred embodiments of the present invention.This memory space expanding system 100 is applied to network equipment 10.Network equipment 10 can be web camera (IP Camera), network video machine (network video recorder, NVR), or other electronic installation.This network equipment 10 is connected to network cloud 30 by network address translation (network address translating, NAT) equipment 20.This network cloud 30 provides multiple high in the clouds memory space to network equipment 10, example memory space 1～high in the clouds, high in the clouds memory space n as shown in Figure 1.These high in the clouds memory spaces can be provided by different cloud computing service providers, can be free, also charge.
Network equipment 10 also has local memory space 40.Local memory space 40 can be built-in by network equipment 10 or the memory device 50(such as safe digital card, the hard disk that connect) etc. provide, also can be provided by Network storage technology (network attached storage, the NAS) equipment 60 that is positioned at same local network network with network equipment 10.
Consulting shown in Fig. 2, is the functional block diagram of memory space expanding system 100 preferred embodiments of the present invention.This memory space expanding system 100 comprises module 110, receiver module 120, checking module 130, memory module 140 and dilatation module 150 is set.Utilize these functional modules, in the time that network equipment 10 need to be stored new data 70, memory space expanding system 100 checks the free space of local memory space 40.If the free space deficiency of local memory space 40, memory space expanding system 100 for example, shifts a part to the high in the clouds memory space that network cloud 30 provides by the previously stored data of local memory space 40 (file a1～an), stores new data 70 to discharge enough spaces at local memory space 40.
Module 110～150 comprises computer programing instruction, these computer programing instructions are stored in the address space of local memory space 40 interior appointments, the processor of network equipment 10 is carried out these computer programing instructions, and the above-mentioned functions of module 110～150 is provided.Below in conjunction with the concrete function of Fig. 3 specification module 110～150.
Consulting shown in Fig. 3, is the flow chart of memory space extended method of the present invention preferred embodiment.
Step S10, arranges module 110 and multiple high in the clouds memory spaces is set supports the priority of support of the local memory space 40 of network equipment 10.Priority of support is set here and refers in the time that network equipment 10 need to be to high in the clouds memory space data on file, first by data storage to which or which high in the clouds memory space.
Before priority of support is set, the access mode relevant information that module 110 is set can first stores all available high in the clouds memory space, the such as access path of each high in the clouds memory space, access account and password etc.Module 110 is set to be for example stored in the access mode relevant information of each high in the clouds memory space, in the configuration file (the default page) of network equipment 10 one by one.
The priority of support arranging can, for according to the sequencing of the access mode relevant information of the high in the clouds memory space of recording in configuration file, when the high in the clouds memory space of specifying is at first filled with after data, then jump to next memory space continuation data on file.The priority of support arranging also can, for the data mean allocation that network equipment 10 is needed network cloud 30 store arrives each high in the clouds memory space at every turn, can also be specified high in the clouds memory space (consulting shown in Fig. 4) according to the time period.
Step S20, receiver module 120 receives network equipment 10 new data to be stored 70.For example, if network equipment 10 is web camera, this new data 70 may be the up-to-date audiovisual materials of shooting with video-corder of web camera.
Step S30, checking module 130 checks the residual capacity of local memory space 40.
Step S40, checking module 130 judges that whether the residual capacity of local memory space 40 is lower than preset value.In the present embodiment, this preset value is according to the data size dynamic setting of new data 70, for example, suppose that new data 70 is for 200MB, and this preset value, for being equal to or greater than 200MB, supposes that new data 70 is 220MB, and this preset value is for being equal to or greater than 220MB.In other embodiments, the fixed value that this preset value also can rule of thumb be set for network manager.If the residual capacity of local memory space 40 is not less than preset value, perform step S50, new data 70 is stored to local memory space 40 by memory module 140.If the residual capacity of local memory space 40, lower than preset value, performs step S60.
Step S60, dilatation module 150 copies the data of local memory space 40 oldest stored, according to priority of support by the data storage copying to corresponding high in the clouds memory space.As shown in Figure 2, if the data of local memory space 40 oldest stored is file a1, dilatation module 150 xcopy a1, then according to priority of support, the file a1 copying is stored to corresponding high in the clouds memory space.For example, suppose that priority of support is for specifying high in the clouds memory space according to the time period, dilatation module 150 determines according to current time the file a1 copying is stored to which high in the clouds memory space.
Step S60, dilatation module 150 is deleted this data being replicated from local memory space 40, and for example file a1, to discharge a part of memory space.Afterwards, flow process is returned to step S30.If again judge, the residual capacity of local memory space 40 is also lower than preset value, the data that dilatation module continues to copy local memory space 40 oldest stored to high in the clouds memory space further to discharge the memory space of local memory space 40.Until the residual capacity of local memory space 40 is equal to or higher than preset value, new data 70 is stored to local memory space 40 by memory module 140.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to above preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
