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.
Claims2
A method comprising:
- receiving blocks of data through a first set of lanes;
- striping the blocks of data among a second set of lanes;
- adding a control character to the striped blocks of data on each of the lanes in the second set of lanes;
- synchronizing the striped blocks of data on the second set of lanes according to the control character;
- and
- wherein the first set of lanes has a different number of lanes than the second set of lanes.
3 more elements
A system comprising:
- a first packet processor that receives blocks of data through a first set of lanes, stripes the blocks of data among a second set of lanes, and adds a control character to the striped blocks of data on each of the lanes in the second set of lanes;
- a second packet processor that receives the striped blocks of data along with the control character on each of the lanes in the second set of lanes, and synchronizes the striped blocks of data on the second set of lanes according to the control character;
- wherein the first set of lanes has a different number of lanes than the second set of lanes.
