Rerouting bus data signals from faulty signal carriers to existing healthy signal carriers

A system comprising:

• at least one computing device having at least one processor;
• and
• at least one computer readable storage medium having program instructions embodied therewith, the program instructions readable/executable by the at least one processor to cause the system to:
• route a plurality of lane signals through a plurality of signal carriers;
• in response to the routing, open, via a first demultiplexer, a plurality of communication channels from a first set of lane signals of the plurality of lane signals, to each of a plurality of multiplexers, the each of the plurality of multiplexers being assigned to a particular set of the plurality of signal carriers, wherein the first set of lane signals have a capability to be re-routed to any of the plurality of signal carriers upon a fault associated with a first set of signal carriers;
• determine that the first set of signal carriers of the plurality of signal carriers are faulty, the first set of signal carriers for transmitting or receiving the first set of lane signals of the plurality of lane signals, the plurality of signal carriers forming a plurality of sequentially ordered lanes, the plurality of lanes comprising a link for use in intercommunication between two or more endpoints of a computing device;
• identify a second set of signal carriers of the plurality of signal carriers that are not faulty, the second set of signal carriers for transmitting a second set of lane signals of the plurality of lane signals;
• and
• re-route, based on the determining and identifying, one or more of the first set of lane signals from the first set of signal carriers through a first subset of the second set of signal carriers, wherein a first channel of the plurality of communication channels from the first demultiplexer to a first multiplexer is selected for the re-routing, the first multiplexer being assigned to the first subset of the second set of signal carriers, the routing of the one or more of the first set of lane signals causing a bandwidth capacity to increase to a highest available bandwidth.
