Abstract

A system and method of mapping fixed-size data packets and variable-size data packets over SONET and SDH is provided. The system and method of mapping fixed-size data packets over SONET and SDH includes buffering ATM cells (230) and mapping the ATM cells in a nxVT superframe (210). In a further embodiment, the mapping includes mapping four ATM cells per VT in the nxVT superframe (210). In a further embodiment, the mapping includes mapping 4n ATM cells in a sequence of byte flow in the nxVT superframe (210), where n is a positive integer. The system and method of mapping variable-size data packets over SONET and SDH includes encapsulating the packets in High-Level Data Link Control (HDLC) frames and mapping the HDLC frames in a nxVT superframe.
