Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
Fig. 1 shows a point-to-point distributed storage method for a local area network according to the present application, which is applied to a local area network system, where the local area network system includes a plurality of user nodes, and the user nodes are connected to a router. The method for the distributed storage of the local area network point-to-point comprises the following steps: s1: one of the user nodes sends a storage demand message to the router. S2: and the router broadcasts the storage demand message to all other user nodes in the local area network. S3: and the user node receiving the storage demand message sends a first position information message containing the position of the user node to the user node sending the storage demand message. S4: and the user node sending the storage demand message sends the source file to a plurality of corresponding user nodes sending the first position information message according to the plurality of received position information messages. The above steps are specifically described below.
For step S1: one of the user nodes sends a storage demand message to the router.
When one of the user nodes, for example, node a, needs to store a source file, node a needs to broadcast a storage requirement to the lan. Specifically, the node a sends a storage demand message to the router. The storage demand message is a UDP protocol message, and it only needs to send a request to the router, and does not need to respond, and does not need to know which nodes receive the broadcast.
For step S2: and the router broadcasts the storage demand message to all other user nodes in the local area network.
After receiving the storage demand message, the router broadcasts the storage demand message to all connected machines in the local area network.
For step S3: and the user node receiving the storage demand message sends a first position information message containing the position of the user node to the user node sending the storage demand message.
Nodes receiving the storage demand message, such as node B, node C, node D, node E, and node F, actively send a first location information message containing their own location information (MAC and IP) to node a. The first location information message is also a UDP request. So for node B, node C, node D, node E and node F, this request consumes little computing resources, while node B, node C, node D, node E and node F are also not concerned about whether node a receives the request.
For step S4: and the user node sending the storage demand message sends the source file to a plurality of corresponding user nodes sending the first position information message according to the plurality of received position information messages.
After the node A receives the first position information of the plurality of nodes, the node A can send source files to the plurality of target nodes through a UDP protocol, and the requirement of point-to-point distributed storage is met.
As a preferred embodiment, a specific method for sending, by a user node sending a storage demand message, a source file to a plurality of corresponding user nodes sending first location information messages according to a plurality of received first location information messages includes:
and the user node sending the storage demand message generates an uploading queue according to the received first position information messages.
And the user nodes sending the storage demand messages transmit the source files to a plurality of user nodes sending the first position information messages according to the uploading queue.
It will be appreciated that in order to avoid network congestion, the amount of network data will become very large if storage reception is initiated to all nodes at once. Therefore, in the present application, the node a sequences the node B, the node C, the node D, the node E, and the node F, and then sequentially transmits the source file to a plurality of user nodes that send the first location information packet.
Preferably, node a will first pick a first number of nodes from node B, node C, node D, node E and node F to send source files.
In a preferred embodiment, the first number is 1 or more and 5 or less.
In the present application, the first number is 2. For example, node a first uploads a source file to nodes C and D, while node B, E and F queue up for upload in an upload queue.
As a preferred embodiment, when one of the user nodes needs to download a file, one of the user nodes sends a download requirement message to the router. And the router broadcasts the downloading demand message to all other user nodes in the local area network. And the user node which receives the downloading demand message and stores the source file sends a second position information message containing the position of the user node to the user node which sends the downloading demand message. And the user node sending the downloading demand message downloads the source file from the corresponding user nodes sending the second position information messages respectively according to the received second position information messages.
It can be understood that when the node a needs to download the source file, the node a sends a download requirement packet to the router, and the router broadcasts the download requirement packet to other nodes. And the user nodes which receive the downloading demand message and store the source file, such as the node B, the node C, the node D, the node E and the node F, send second position information messages to the node A. After receiving the second location information for the node(s), node a may download source files from the plurality of destination nodes via the UDP protocol. Preferably, the download request message and the second location information message are UDP protocol messages.
As a preferred embodiment, the specific method for downloading the source file by the user node sending the download demand message according to the received plurality of second location information messages from the corresponding plurality of user nodes sending the second location information messages includes:
and the user node sending the downloading demand message divides the source file to be downloaded into a plurality of files, and the downloaded files are assembled into a finished source file from one file corresponding to the user nodes sending the second position information messages respectively after the downloading is finished.
It can be understood that, when downloading a file, if a node is suddenly offline (the machine is shut down or crashed), the program can record the downloading progress, so that the switching node can perform breakpoint resuming, and time is saved. In addition, the file can be divided into a plurality of parts, the parts are transmitted by a plurality of nodes at the same time, and the parts are assembled into a complete file after transmission is finished, so that the file submitting efficiency is high.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
