  • Protocol translation method and bridge device for switched telecommunication and computing platforms
    Patent number: 9323708
    Abstract: A computing and communication architecture utilizes a serial protocol based switched fabric among circuit cards housed in packaging arrangement. In one embodiment, each circuit card connected to the serial protocol based switched fabric in the packaging arrangement is provided with a protocol processor that enables all of the circuit cards to efficiently provide packet-based serial self-clocked communications at line speed. As a result, it is not necessary to arrange the circuit cards in a hierarchical manner in order to address the problems of switch blocking and related traffic congestion issues that would otherwise limit the implementation of the serial protocol based backplane arrangement for housing circuit cards.
