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.
Claims21
1-2. (canceled)
A method comprising:
- detecting, by a receiver device, a stripe synchronization error with respect to a plurality of stripes received at the receiver device, the stripe synchronization error indicating that the plurality of stripes are out of sync;
- and
- outputting, by the receiver device, a signal in response to the detecting.
A receiver device comprising:
- control logic configured to:
- detect a stripe synchronization error with respect to a plurality of stripes received at the receiver device, the stripe synchronization error indicating that the plurality of stripes are out of sync;
- and
- output a signal in response to the detecting.
A method comprising:
- receiving, by a transmitter device, a signal indicating that a plurality of stripes sent by the transmitter device are out of sync;
- temporarily suspending, by the transmitter device, transmission of data via the plurality of stripes;
- and
- sending, by the transmitter device, a sequence of first control characters via the plurality of stripes.
A transmitter device comprising:
- control logic configured to:
- receive a signal indicating that a plurality of stripes sent by the transmitter device are out of sync;
- temporarily suspend transmission of data via the plurality of stripes;
- and
- send a sequence of first control characters via the plurality of stripes.
