For next-generation optical access systems, we developed a 10G/1G dual-rate EPON OLT LSI that fully conforms to the IEEE 802.3av standard. To support three types of ONUs (GE-ONU and symmetric/asymmetric 10G-ONUs), we adopted the 802.1AE algorithm and GE-PON encryption algorithm, which was adopted before 802.1AE standardization. We implemented a dynamic-bandwidth-allocation-information-based method for algorithm control in order to dynamically select the decryption algorithm that corresponds to the encryption algorithm used by the ONU burst by burst. In addition, while basically conforming to 802.1AE standard, we widened the category of encrypted frames to include multipoint MAC control protocol (MPCP) frames and operation, administration, and maintenance (OAM) frames, by adding three simple steps of functions to existing blocks with little hardware overhead. We implemented the method and the expansion mechanism in a 10G/1G dual-rate EPON OLT LSI and demonstrated that it works correctly. |
