Title: (EN) Rerouting bus data signals from faulty signal carriers to existing healthy signal carriers
Abstract: front page image
(EN)

A first set of signal carriers of a plurality of signal carriers may be determined to be faulty. The first set of signal carriers may be for transmitting a first set of respective lane signals of a plurality of lane signals. A second set of signal carriers of the plurality of signal carriers may be identified as not faulty. The second set of signal carriers may be for transmitting a second set of lane signals of the plurality of lane signals. Based on the determining and identifying, one or more of the first set of lane signals may be routed from the first set of signal carriers through a first subset of the second set of signal carriers, the routing of the one or more of the first set of lane signals may cause a bandwidth capacity to increase to a highest available bandwidth.
