Abstract: Per-interface electronic device protection switching systems and methods are disclosed. An electronic device and each communication line interface provided in the device are monitored, and device information and interface information are generated. The device and interface information is periodically sent to a mate electronic device in a protection group to which the electronic device belongs. Mate device information and mate interface information are also received by the device from the mate device. Activity states of each device interface are controlled based on at least one of the device information, the interface information, the mate device information, and the mate interface information.

Abstract: Electronic memory update methods, systems, and related data structures are disclosed. When a memory update is to be performed, a first section of the memory is updated to store a first software code segment, under control of a second software code segment stored in a second section of the memory. The second section of the memory is then updated under control of the first software code segment, after completion of updating the first software code segment. An incomplete update of one of the first and second sections of memory may be subsequently detected and remedied by executing the software code segment stored in the other of the first and second sections of the memory. The risk and effects of incomplete memory updates are thereby substantially reduced.
