1. A system comprising:

  • a plurality of switching devices, a first switching device, of the plurality of switching devices, connected to a second switching device, of the plurality of switching devices, by a plurality of signal paths,the first switching device is to;

    receive an instruction to switch from a first path, of the plurality of signal paths, to a second path, of the plurality of signal paths, where the first path is different from the second path, andperform, in response to the received instruction, a first switching operation to connect the first path, at an input of the first switching device, to the second path, at an output of the first switching device; and

    the second switching device is to;

    receive the instruction to switch from the first path to the second path,detect a loss of signal on the first path as a result of the first switching operation performed by the first switching device, andperform, in response to detecting the loss of signal on the first path, a second switching operation to connect the first path, at an output of the second switching device, to the second path, at an input of the second switching device.
