Abstract
In a shaping method of controlling interval of transmission of cells to a transmission path, an input cell is temporarily accumulated in a buffer memory such that transmission time of the input cell is decided according to a traffic condition beforehand registered for each VPI and a traffic condition registered in advance for each VPI/VCI. The conditions are stored in a parameter table. The transmission time is compared with transmission time assigned to each of the preceding cells accumulated in the buffer memory. If conflict occurs therebetween, the transmission time is corrected and then correspondence between the transmission time and identifying information of the input cell are stored in an output control memory. Referring to the memory, the cells are read from the buffer memory in the sequence of transmission time to be sent to an output communication line.
