Abstract

PURPOSE:To improve a data transfer efficiency in the case of transferring the same data from a certain node to plural nodes by setting plural destinations at the address part of a data frame, and re-constructing the data frame at every same delivery link from a route at every destination at each receiving node. CONSTITUTION:Firstly, at a node address F, data parts except for an address F are stored in a storage means in the same node when the data frames of the addresses (C-F) of the destination are received. After that, the data frame whose destination addresses are C and D and having the same data part is generated by a frame generating means, and it is transmitted to the node D by a transmission/reception means. Next, at the node address D, the data part is stored in the storage means in the node, and following that, two data frames having the same data part are generated by the frame generating means, and they are transferred to the node address C and the node address E by the transmission/reception means, receptively. In such a way, the data transfer efficiency can be improved.

(Problem to be Solved by the Invention) In the first conventional method described above, when trying to send the same data from one node to multiple other nodes, the 1-to-n transfer is changed from the 1-to-1 transfer to n. It is necessary to carry out the transfer once and then transship the transfer, which has the drawback of low data transfer efficiency.

An object of the present invention is to set the addresses of multiple destinations in the address section of the data frame when transferring the same data from one node to multiple other nodes, and each node receives the same data by setting its own address. The above disadvantages are eliminated by using the addresses of the remaining destinations as the address part of the same sending link, regenerating the data frame, and configuring multiple nodes in a tree shape, thereby improving transfer efficiency. The purpose is to provide a data transfer method.
