Re-programming of deluge

For the reprogramming technology, I know is not particularly profound, the general meaning is that in human difficult to direct contact with the environment, through the wireless message transmission will need to manipulate the node's relevant instructions to transfer to the node and make it run related operations. Here, take the deluge protocol as an example to illustrate the problem of reprogramming.

The Deluge protocol is one of the distribution protocols that pass instructions to each node through flood transport and get the latest information. In the transmission process through 3 handshake, first the base station node sends ADV (message metadata) to the surrounding nodes to tell them, I have a message, do you want to, the surrounding node received ADV after the message version number to query their own message list to see if there is no such version, if none, then feedback a req message to the base station node. When the base station node receives the Req, it begins transmitting data. Thus, the instructions are communicated through 3 handshakes.

Second, the deluge protocol is capable of transmitting big data because he divides chunks of data into one page of data, and then each page is divided into one packet (16 bytes per packet), one packet at a time, one page after another, and the transmission gap has a wait time. A large program is sent to the target node by decomposing the program.

For the time being to write about deluge content is almost these, then thought will continue to add, and will continue to improve the operation of deluge.

About the operation of the Deluge and the official website to provide almost, just to note that there are several:

1 to have two nodes, a set to Basestation burning Basestation folder under the program, a set into the client node burning Goldenimage folder program (the rest of the operation in the Base station node operation)

2 The new image to be added is first added to the Base station node and then distributed through the base station node.

3 to add the components Delugec to the Blinkappc file, just add it and no additional action is required.

4 the last to add Volumes-stm25p.xml file contains the division of the Blockstorage.

In general, these sections will continue to study reprogramming operations (mainly deluge) later on.
