<p>A method for processing overhead of optical network and apparatus thereof, the said overhead processing means includes: an overhead memory, an overhead processor, and an overhead processor control module. The said overhead processor control module is used for controlling the operation of the said overhead memory and the overhead processor. The method includes that a system chip entries the time slots of all overhead bytes that will be processed and descrambled data, and corresponding virtual container number, the said overhead processor encodes the byte and stores all overhead byte of the same channel in the address of the same overhead memory; at the same time it stores in turn the overhead byte of the different channels in the different address space based on the virtual container number, so overhead processing logic polls the processing. The method and apparatus contraposes the overhead of large capacity chip only uses a set of overhead processing logic, and saves the area and power consumption smartly, thereby reduces the production cost.</p> |
