1. A method comprising:
- detecting, by a receiver device, a stripe synchronization error with respect to a plurality of stripes received at the receiver device, wherein each stripe in the plurality of stripes includes a slice of a data packet that is less that the entirety of the data packet, and wherein the stripe synchronization error indicates that the plurality of stripes are temporally skewed; and
outputting, by the receiver device, a signal in response to the detecting.

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.

13. A method comprising:
-
receiving, by a transmitter device, a signal indicating that a plurality of stripes sent by the transmitter device are temporally skewed, each stripe in the plurality of stripes including a slice of a data packet that is less that the entirety of the data packet; 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. - View Dependent Claims (14, 15, 16, 17, 18)
