Abstract:
1. A frame relay apparatus, comprising: a receiver to receive a plurality of frames via a first network; a determiner to determine whether or not each of the received frames includes a payload that is set by fragmentizing an original data; a payload extractor to extract the payloads from the frames to associate with the original data when said determiner determines that the frames include said payloads; a frame assembler to assemble one frame by combining the extracted payloads for every associated original data; and a transmitter to transmit the assembled frame to a second network, a data manager to refer to a frame every time a frame is determined to include said payload by said determiner, count the number of determinations for every original data associated with the payload, and manage the counted number, wherein said payload extractor adds a frame header and a packet header of the frame determined to the payload to be extracted, based on the counted number managed by said data manager, wherein said payload extractor extracts the payload with said added frame header and said added packet header as the first payload of said one frame to be assembled when the counted number managed by said data manager is a predetermined number, and extracts only the payload from the determined frame as a subsequent payload of said one frame to be assembled when said counted number is a number other than the predetermined number, and said frame assembler assembles said one frame by combining the extracted first payload and the subsequent payload.
