  • System and method for communicating asynchronous transfer mode cells in a network environment
    Patent number: 7136384
    Abstract: A method for communicating data is provided that includes receiving an asynchronous transfer mode (ATM) cell at a line card and generating an Ethernet frame that comprises the received ATM cell, an Ethernet-compatible header, and a data integrity element. The Ethernet frame is communicated to a first destination. The Ethernet frame is received at the first destination and directed to a second destination. At the second destination, the Ethernet frame is segmented into portions and reassembled in order to form an Ethernet packet. The Ethernet packet is then communicated to the first destination.
