PACKET COMMUNICATION METHOD, PACKET COMMUNICATION DEVICE AND PACKET SWITCHER

摘要

In a packet communication method, a packet communication device, an input transmission frame of V (b/sec) consisting of a transmission overhead of VOH (b/sec) containing control information for transmission and a pay load of Vp (b/sec) of c (= a+b) bytes, the outer cell consisting of an information field of a b-byte length containing transmission data and a header field of an a-byte length containing a first control information for transmitting the information field. The transmission overhead is removed from and a second control information is added to the input transmission frame. The input transmission frame with the second control information and without the transmission overhead is converted to a plurality of inner cell trains of f (= b+j) bytes length, the inner cell trains consisting of an information field of a b-byte containing the transmission data and a second header field of j (= a+d) bytes consisting of the first control information and the second control information (where f x g = h x V, h is an integer or a fraction of an integer). Packets switching are performed on each inner cell. A plurality of inner coils are converted to an output transmission frame of V (b/sec) having the same format as the input transmission frame for transmission.
