Abstract
Method and apparatus for segmenting variable length frames into fixed length cells in a network equipment. The method allows preparing information to build the cells resulting in the segmenting of a succession of frames directed to the same destination in said network equipment. The cell may be packed with more than one frame. The cell information comprises the address where to read the frame data in a first storage unit, the cell header itself which indicates if the cell includes data from one packet or for more packets, a pointer per each of said more packets, designating the place of the end of data of the previous packet in the cell and a cell type field indicating one of the following types: a start of a new frame type, a continuation of frame type, a end of current frame type and a start and a end of a new frame type. The segmenting apparatus comprises a finite state machine using an Add/substract unit to compute the cell information and write said cell information in a second storage unit.
