Abstract:
1. A method for overhead processing in an optical network, comprising: receiving overhead bytes and virtual container numbers corresponding to the overhead bytes; storing overhead bytes of different paths in different address spaces of an overhead memory according to the virtual container numbers; obtaining an overhead byte to be processed by polling the different address Spaces of the overhead memory; determining a corresponding overhead processing unit for the overhead byte of the stored overhead bytes according to a type of the overhead byte; processing the overhead byte by the corresponding overhead processing unit; wherein the number of the overhead processing units corresponding to a type of the overhead bytes is less than the number of the paths; and the obtaining the overhead byte to be processed by polling the different address spaces of the overhead memory comprises: processing the overhead byte if it is determined that the byte code of the overhead byte is different from the byte code of the former polled overhead byte.
