As shown in Fig. 2, the cloud mobile phone framework of the prior art is: Duo Taiyun mobile phone is connected on 1 shared interchanger, then will
The interchanger is connected to network storage cluster.And for reasons of cost, the outlet of the shared interchanger is only gigabit networking, when big
Measuring cloud mobile phone, from network storage when read-write data, gigabit networking is not enough to support the scene needs simultaneously.Therefore exist at this
Performance bottleneck, bandwidth wretched insufficiency.And 10,000,000,000 interchangers are expensive, no matter new equipment production or old device upgrade change
It makes, bring cost and risk is excessively high.
Present invention mainly solves the problem of be to improve shared interchanger exit bandwidth under the premise of not changing hardware
Service efficiency, making it no longer is the bottleneck of whole system.
As shown in figure 3, specifically, main process flow of the invention is as follows: when First cloud mobile phone (i.e. the first equipment)
When reading data, from reading file destination in storage cluster (i.e. network storage module).And (i.e. second sets second Yun Shouji
It is standby) read data when, if read data just with First read it is identical, directly read from First cloud mobile phone
Data, since the stream compression in second of reading process is only inside shared interchanger, and do not have to by its it is externally ported with
Storage cluster interaction, so no longer occupying the bandwidth in the exit, is greatly saved its network flow.
Referring to Fig.1, the specific works mistake of the data sharing method between inventive network storage cloud mobile phone is described below in detail
Journey:
S1, carry network storage catalogue, the network storage catalogue include storage letter of the file destination in the first memory
Breath；
Specifically, equipment A (i.e. the first equipment) carry network storage catalogue includes a file F (i.e. target in the catalogue
File).
S2, by network storage catalogue sharing to network；
Specifically, the step S2 the following steps are included:
S21, the first NFS system of starting；
S22, pass through the first NFS system for network storage catalogue sharing to network.
Specifically, equipment A (i.e. the first equipment) starts NFS server-side (i.e. the first NFS system), and the catalogue is disclosed
On network, read so that NFS client (i.e. the 2nd NFS system) is shared.
S3, according to the first file read request, determine in the first memory there is no after file destination, pass through network storage mould
Block obtains file destination；
Specifically, the application program in equipment A (i.e. the first application program) reads file F from network storage catalogue, this
When memory in there is no this document, therefore actual data are read from network storage by " egress switch ", and by this document
Data are stored in the memory of equipment A.
S4, the network storage catalogue for obtaining the first equipment carry；
Specifically, equipment B (i.e. the second equipment) utilizes NFS client (i.e. the 2nd NFS system), disclosed in carry equipment A
Catalogue (including file F).
S5, according to the second file read request, pass through network storage catalogue and read file destination；
Specifically, the application program in equipment B reads this document F, and NFS client will by " internal switch " at this time
Read request is sent to the NFS server-side of equipment A.
When NFS server-side reads file F, existing this document in memory is found, so directly reading from equipment A memory
Access evidence, and equipment B is returned to by " internal switch ".Therefore equipment B reads same file F, without again passing by " outlet
Interchanger " is read from network storage.Complete the purpose of saving " egress switch " bandwidth.
When NFS server-side reads file F, find that this document is not present in memory, then the second equipment is from network storage mould
Block obtains file destination.
To sum up, after First cloud mobile phone reads data, due to the design of android operating system itself, the data
It can be automatically saved in the cloud mobile phone EMS memory.So guaranteeing real-time to accelerate secondary reading, select directly from first
Data are read in platform cloud mobile phone EMS memory.
Realization principle of the invention is as follows: in Android system or linux system, for the reading of application layer process initiation
Request, system can first go in cache layers of the page in kernel (i.e. memory) to search, if the data have existed, hit is slow
It deposits, is directly returned the result from memory.If miss, read request continues downwards, until final block layer is (in the present invention
In, block layers are network storage module).
As shown in figure 5, application program carries out the process of data read operation specifically:
1, app, that is, application program initiates read data request, for example reads certain a line of a file.
2, it reads request to up to VFS, i.e. Virtual File System, because there are a variety of file system in Linux, such as ext4,
Nfs, for compatibility, one middle layer VFS of design of Linux, it can be understood as forwarding, will practical read-write be forwarded to it is specific
File system on.
3, NFS or EXT4 can first go in memory (i.e. page cache) to search, if it find that institute after receiving read request
It needs data to have existed, then directly data is read out and returned, finally return that app.
If 4, in page cache without this data, continuing down-call, block device layer is reached, by driver,
Finally read out from storage medium (disk, USB flash disk or network).
5, the data that will be read out, are written in pagecache, referring next to the layer-by-layer returned data of above-mentioned steps 4.Together
When, it, can be through steps 1 and 2 and 3, directly when next time reads the data again since this has write data into page cache
Returned data.Without again via step 4 and 5.
Therefore, it is necessary in the application layer of two cloud mobile phones, increase a pair of of client and server-side, and need support
POSIX file system api, in this regard, realization principle of the invention is as follows: the file read-write that the process of host where client is initiated
Request, needs to be sent to server-side, carries out practical read-write in the machine by server-side, then data are transmitted back to client by network
End, finally returns that client process.The partial function selects open source software NFS to complete, and since NFS itself does not support ARM frame
Structure transplants nfs-utils, rpcbind with libtirpc to be used in cloud mobile phone.
NFS described in the present embodiment includes client and server-side, in the specific use process, client and server-side point
Other installation and deployment are on different devices (the cloud mobile phone i.e. in the present embodiment).As shown in figure 4, the realization principle of NFS system is specific
Are as follows:
1, NFS server-side, which need to configure, will open to attributes such as the local directory of client and access authority, and start
Rpcbind service is serviced with nfsd.Wherein rpcbind service can monitor 111 ports of the machine, wait network connection.And nfsd
Service random selection a port is monitored, and waits network connection, while the port being carried out to rpcbind service registration
It informs.The actual port of nfsd is saved in rpcbind at this time.
2, client executing executes mount order using server-side ip and carries out carry to nfs file system, at this time nfs visitor
Family end can access 111 ports of server-side, i.e. rpcbind.The server-side i.e. reality of nfsd saved inside it is got simultaneously
Border listening port.In this way, client the nfsd of the port and server-side can be used to be communicated.
3, it is now placed in some application program of server A, to the nfs catalogue of carry in 2, initiates read-write requests, such as
Read a file.Since client and server-side have built up connection in 2, after NFS client receives the request, will ask
It asks and is converted into the request of rpc far call, server-side is sent to by network.
4, after server-side receives rpc request, Linux local file system interface is called, is read from disk or memory
Actual data are taken, return to client eventually by network, then app application program is returned data to by client.
The tools chain that transplanting is mainly provided using Google ndk described in the present embodiment, on ubuntu to nfs-util,
Tri- programs of rbdbind, libtirpc and library source code carry out cross compile.Finally (cloud mobile phone can be corresponded in arm equipment
Android system) on run.Substantially steps are as follows:
1, the configure of nfs-util, rbdbind, libtirpc, modification compiling option are configured, configuration tool chain becomes
Amount etc..
2, since android uses the library bionic, the definition and function in the library many standard c is lacked, it is therefore desirable to modify
Nfs-util, rbdbind, libtirpc source code delete unnecessary function, modification macrodefinition, rewrite power function to be adapted to
bionic。
3, makefile is generated using configure finally compile out libtirpc.a Static-link Library and Dynamic-link.
4, rbdbind is compiled out in conjunction with libtirpc.a.
5, compiled out in conjunction with libtirpc and rbdbind executable file exportfs in nfs-utils,
mountstats、nfsiostat、nfsstat、rpc.mountd、rpc.nfsd、rpc.statd、showmount、sm-
notify、start-statd。
To sum up, whole implementation process of the invention are as follows: the starting of NFS server-side is in the cloud mobile phone A that first time reads data.
In the cloud mobile phone B that NFS client terminal start-up reads data in second.Since A had read data, and it is stored in memory cache
In.Therefore when B is read out same file again by NFS client, read requests can be forwarded to the NFS service of A
On end, the page cache of A is directly hit via NFS process and returns data to B, no longer via the block layer of A, also just not
It needs to read from network storage cluster by shared interchanger, to save outlet bandwidth resource.
In conclusion the outlet gigabit bandwidth interchanger of prior art, maximum supports 4 cloud mobile phones concurrently to read number
According to.And after using new departure of the invention, every cloud hand-set host can voluntarily provide 4 cloud mobile phones and read.Therefore total band
Wide to save about 4 times, system concurrency amount improves 4 times.
