Abstract
The present disclosure provides a protection group superposition switching method, a control apparatus, and an optical communication device. Multiple protection state machines are implemented by using a field programmable gate array (FPGA). Each protection state machine independently performs an automatic protection switching (APS) protocol operation for at least one protection group that is pre-associated with the protection state machine. At least one protection status table for recording a status of each protection group is updated according to a result of the APS protocol operation, and a cross-connection table for traffic cross-connection between communication units is updated according to the protection status table; the updated cross-connection table is configured into a cross-connection chip, so that the cross-connection chip performs traffic cross-connection according to the updated cross-connection table.
