Abstract
The method for converting cell-based ATM traffic to frame-based ATM traffic comprises assembling a group of one or more cells of a input cell stream which corresponds to an AAL5 PDU; extracting a user data payload of the AAL5 PDU, exclusive of any padding; constructing a frame-based ATM adaptation layer protocol data unit (FB-AAL PDU) having no padding using the AAL5 PDU payload; and segmenting the FB-AAL PDU into one or more frames to generate an output frame stream. The method provides an increase in bandwidth efficiency since the padding overhead required by AAL5 PDUs is eliminated when transferring data to, over or across a frame-based ATM network.
