<p>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 (2, 21, 111, 202). The transmission overhead is removed from and a second control information is added to the input transmission frame (2, 201, 21, 23, 24, 25). 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) (2, 203). Packets switching are performed on each inner cell (3). A plurality of inner cells are converted to an output transmission frame of V (b/sec) having the same format as the input transmission frame for transmission (4, 41, 204, 205, 206, 112).</p> |
