The the second account book matching stored in point sends connection to the first memory node and establishes if the first account book and the matching of the second account book
Instruction, the connection establish instruction and are used to indicate the first memory node and the foundation connection of the second memory node.
First account book and the matching of the second account book refer to the operation behavior and the of the first memory node recorded in the second account book
The operation behavior of the first memory node recorded in one account book is identical.
For example, if file fragment Y is sent to the storage section of the third in distributed file storage system by the first memory node
After point, the third account book that is stored in third memory node has obtained the unique identifying information that file fragment Y can be recorded in inventory
And first memory node device identification；After if file fragment Y is sent to the second memory node by third memory node, the
The device identification for having obtained unique identifying information, third memory node that file fragment Y can be recorded on inventory of two account books and
The device identification of first memory node；Therefore, when having sent for the first account book has recorded the unique identification of file fragment Y on inventory
The device identification of information and third memory node, and the record on inventory that obtained of the second account book has unique knowledge of file fragment Y

The debt ratio of storage node is not higher than sending after debt ratio threshold value.Debt ratio is used to indicate the first memory node and needs to distribution
Memory node is sent, but the ratio that the file fragment not sent is shared in the file fragment that the first memory node transmits.
Illustratively, the second memory node is after determining the first account book and the matching of the second account book, according in the first bill
The file fragment number in inventory and the file fragment data in unfinished inventory have been sent, the first memory node is calculated
Debt ratio.If the debt ratio is higher than debt ratio threshold value, it is determined that the first memory node is node of doing evil, and stops saving with the first storage
The communication of point；If the debt ratio is not higher than debt ratio threshold value, link order is established to the transmission of the first memory node.Wherein, make
It refers to the higher memory node of debt ratio to dislike node.The usual higher node of debt ratio is normally present the storage section of the system failure
Point, node of doing evil can send the account book of mistake to other memory nodes, or, after the transmission request for having responded other memory nodes
There is no the file fragments for sending the request of other memory nodes.
Step 203, instruction is established according to connection and the second memory node establishes connection, demand is sent to the second memory node

First memory node establishes link order and the foundation connection of the second memory node according to what the second memory node was sent
Afterwards, the unique identifying information of demand file segment is sent to the second memory node.Optionally, unique knowledge of the demand file segment
Other information is the cryptographic Hash of demand file segment.
Illustratively, after the first memory node and the second memory node establish connection, if the first memory node demand
For demand file segment A, demand file segment B and demand file segment C, then the first memory node is sent out to the second memory node
Send the unique identifying information of demand file segment A, the unique identifying information of demand file segment B and demand file segment C
Unique identifying information.
Step 204, the demand file segment that the second memory node is sent is received, and merges and obtains demand file.
First memory node receives the demand file segment that the second memory node is sent, and demand file segment, which is merged into, to be needed
Seek file.
Illustratively, the second memory node receives the unique identifying information of demand file segment A, demand file segment B
Unique identifying information and demand file segment C unique identifying information after, according to the unique of the demand file segment of acquisition
Whether identification information is stored with demand file segment A, demand file piece by the way that the inventory of the acquisition detection in the second account book is local
Section B and/or demand file segment C sends demand file if demand file segment A has been locally stored to the first memory node
Segment A；If demand file segment A and demand file segment B has been locally stored, demand file is sent to the first memory node
Segment A and demand file segment B；If demand file segment A and demand file segment C has been locally stored, deposited to first
It stores up node and sends demand file segment A and demand file segment C；If demand file segment B and demand text has been locally stored
Part segment C then sends demand file segment B and demand file segment C to the first memory node.First memory node receives
