Abstract
A method and system 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 user data traffic including PTM traffic organized into variable length packets, each packet comprising a variable length data payload and an original fixed length PTM packet header. The original PTM header is converted into an ATM-like header including a flag (F) identifying the packet as being a PTM packet, a label indication made to orient the currently-considered PTM packet within the ATM network nodes, a count (CNT) field for storing the PTM payload length indication therein to enable locating the PTM payload end position and a Header Error Control (HEC) field for storing an ATM-like error control byte (HEC) therein, which enables transporting the PTM packets over the ATM network links without having to chop the PTM payload into predefined fixed length segments by adding dummy bits to the last segment if required.
