COMMUNICATIONS METHOD, SYSTEM, AND APPARATUS FOR OPTICAL NETWORK SYSTEM |
摘要 |
The present invention provides a method, a system, and an apparatus for data communication in an optical network system. A new encoding scheme is implemented in the following manner: performing 32-bit to 34-bit encoding on a data stream on which 8-bit/10-bit decoding has been performed, performing forward error correction encoding on the data stream on which the 32-bit to 34-bit encoding has been performed, and sending the encoded data stream; or performing forward error correction decoding on a received data stream, and performing 32-bit to 34-bit decoding on the data stream on which the forward error correction decoding has been performed. In this way, a bandwidth resource of a line is saved; line monitoring can be implemented without interrupting a service, which is easy to implement and greatly improves various types of performance of the system. |

1. A communications method for an optical network system, wherein the communications method comprises:
receiving a data stream from a physical medium attachment layer at a line rate, wherein the data stream is a data stream on which 8-bit/10-bit encoding has been performed; performing 8-bit/10-bit decoding on the received data stream; performing 32-bit to 34-bit encoding on the data stream on which the 8-bit/10-bit decoding has been performed; performing forward error correction encoding on the data stream on which the 32-bit to 34-bit encoding has been performed; performing bit width conversion of 34-bit/10-bit on the data stream on which the forward error correction encoding has been performed; and sending the data stream on which the bit width conversion has been performed to a physical medium dependent layer at the line rate. |
