Abstract
A backplane interface adapter with error control and redundant fabric for a high-performance network switch. The error control may be provided by an administrative module that includes a level monitor, a stripe synchronization error detector, a flow controller, and a control character presence tracker. The redundant fabric transceiver of the backplane interface adapter improves the adapter's ability to properly and consistently receive narrow input cells carrying packets of data and output wide striped cells to a switching fabric.
Claims23
A method comprising:
- distributing, by a transmitter device, blocks of data across a plurality of stripes, the distributing comprising inserting, between the blocks of data, control information in each stripe at a predetermined data interval, the control information being operable for synchronizing the plurality of stripes at a receiver device;
- and
- transmitting, by the transmitter device, the plurality of stripes in parallel to the receiver device.
A transmitter device comprising:
- one or more hardware control components configurable to:
- distribute blocks of data across a plurality of stripes, the distributing comprising inserting, between the blocks of data, control information in each stripe at a predetermined data interval, the control information being operable for synchronizing the plurality of stripes at a receiver device;
- and
- transmit the plurality of stripes in parallel to the receiver device.
A method comprising:
- receiving, by a network device, a plurality of stripes, each stripe including blocks of data and control information interspersed between the blocks of data at a predetermined data interval;
- and
- synchronizing, by the network device, the plurality of stripes using the control information in each stripe.
A receiver device comprising:
- one or more hardware control components configurable to:
- receive a plurality of stripes, each stripe including blocks of data and control information interspersed between the blocks of data at a predetermined data interval;
- and
- synchronize the plurality of stripes using the control information in each stripe.
