Embodiment
The purpose of the embodiment of the invention is to provide storage, reads, transmission method and management server and network node; Can avoid carrying out the great burden that big transfer of data is brought to network through the switching network between the node in the prior art; Reduce the consumption of the transfer resource of switching network, improved the service quality of network.
Be described in detail in the face of what the embodiment of the invention provided down.
Embodiment one, a kind of method of storage, and flow chart is as shown in Figure 1, comprising:
101, the data storage request that the management server receiving node sends;
Said node can be the network equipment that work station, computer, server etc. are used for transfer of data, exchange or handle.
In the present embodiment, can comprise the size of said data in the data storage request that said node sends.
102, said management server is said data allocations memory space in the shared memory territory and the address of said memory space is returned to said node;
If comprise the size of said data in the data storage request of said step 101, then said management server can be said data allocations memory space in the shared memory territory according to the size of said data.It is understandable that said management server also can be each data and all distribute fixing memory space not according to the big or small dividing data memory space of said data, concrete memory space dividing mode is not construed as limiting the invention.
It is understandable that, can also comprise after the data storage request that said management server receiving node sends:
Said management server is said data allocations storaging mark, and writes down the corresponding relation of the address of said storaging mark and said memory space.
The storaging mark here can be used for identifying the uniqueness of said data at network, if management server changes the address of said data memory space of distribution in the shared memory territory, then upgrades the corresponding relation of the address of said storaging mark and memory space; When node reads these data through this storaging mark, then can guarantee the correctness of reading of data.
In the present embodiment, the network entity of said management server for storage administration is carried out in the shared memory territory.
103, said node deposits said data in said shared memory territory according to said address.
Said node can be connected through the dedicated data transmission passage with said shared memory territory; Said node deposits said data in said shared memory territory through said dedicated data transmission passage; The dedicated data transmission passage here can be: fibre optic data transmission passage or small computer system interface (Small Computer System Interface, SCSI) transmission channel.
