ATM transfer system of data packets

An ATM (Asynchronous Transfer Mode) transfer system of data packets comprising an ATM network having a transmitter-side exchange and a first and a second receiver-side exchange, a transmitter-side network terminal connected to the transmitter-side exchange, a first and a second receiver-side network terminal connected to the first and the second receiver-side exchange, respectively, a first and a second packet transmitter connected to the transmitter-side network terminal, and a first and a second packet receiver connected to the first and the second receiver-side network terminal, respectively;

• wherein:
• the first packet transmitter sends out a first data packet destined to the first packet receiver;
• the second packet transmitter sends out a second data packet destined to the second packet receiver;
• the transmitter-side network terminal sends out an original ATM cell to the transmitter-side exchange, said original ATM cell being multi-loaded with the first and the second data packet;
• the transmitter-side exchange duplicates the original ATM cell into the same number of duplicated ATM cells with a number of data packets multi-loaded on the original ATM cell, a first and a second duplicated ATM cell of the duplicated ATM cells being sent out to the first and the second receiver-side exchange, respectively, each accommodating each of the first and the second packet receiver whereto respective each of the first and the second data packet is destined;
• the first receiver-side exchange extracts only the first data packet destined to the first packet receiver accommodated in the first receiver-side exchange from the first and the second data packet multi-loaded on the first duplicated ATM cell, and sends out a first new ATM cell loaded only with the first data packet to the first receiver-side network terminal connected to the first packet receiver whereto the first data packet is destined;
• the second receiver-side exchange extracts only the second data packet destined to the second packet receiver accommodated in the second receiver-side exchange from the first and the second data packet multi-loaded on the second duplicated ATM cell, and sends out a second new ATM cell loaded only with the second data packet to the second receiver-side network terminal connected to the second packet receiver whereto the second data packet is destined;
• the first receiver-side network terminal processes the first new ATM cell into the first data packet, and sends the first data packet to the first packet receiver whereto the first data packet is destined;
• and
• the second receiver-side network terminal processes the second new ATM cell into the second data packet, and sends the second data packet to the second packet receiver whereto the second data packet is destined.
