Abstract:
A method for optimizing transmission links bandwidth utilization in an Asynchronous Transfer Mode (ATM) packet switching network including switching nodes interconnected by high speed transmission links, said network being made to transport users' data traffics including so called PTM traffic organized into variable length packets each packet comprising a variable length data payload and an original fixed length PTM packet header, said method being characterized in that it includes converting said original PTM header into an ATM-like header including a flag (F) identifying the packet as being a PTM packet, a label indication made to orient the PTM packet within the ATM network, a count (CNT) field for storing a PTM payload length indication therein to enable locating a PTM payload end position and a Header Error Control (HEC) field for storing an ATM-like error control byte (HEC) therein, attaching said converted header to the payload to derive a PTM frame to be transmitted over the ATM network.
