  • Efficient implementation of 1+1 port redundancy through the use of ATM multicast
    Patent number: 6895024
    Abstract: A switching system. The switching system includes a first switch having a primary receive port and a secondary receive port. The switching system includes a second switch connected to the first switch. The second switch has n receive ports, where n is greater than or equal to 2 and is an integer. The second switch has m transmit ports, where m is greater than or equal to 2 and is an integer. The transmit ports are decoupled from the receive ports. The second switch has a connecting mechanism that includes a multicast mechanism which sends data out a primary transmit port of the m transmit ports to the primary receive port of the first switch to define a primary path, and out a secondary transmit port of the m transmit ports to a secondary receive port of the first switch to define a redundant path to the primary path so that if there is a failure of the primary path to provide the data to the first switch, the data is received by the first switch through the redundant path.
