Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] For the PLOAM messages that will cause the above problems, the existing processing of the PON is obviously not enough. It is necessary to obtain the execution results of the message-related processing on the ONU, so that the OLT can perform correct processing in the next step.

[0050] The solution is mainly:

[0051] First, expand the existing Ack message and add a field DM_Result indicating the execution result. The values ​​can be divided as follows:

[0052] a. 0x00: success;

[0053] b. 0x01: wrong message type;

[0054] c, 0x02: ONU does not support this message;

[0055] d. 0x03: Exceeds the parameter range of the ONU or the upper limit of the number of configurations; (if a certain configuration has only one limit, use this value)

[0056] e. 0x04: Exceeds the parameter range of the ONU or the lower limit of the configured quantity;

[0057] f, 0x...

Abstract

The provided PON PLOAM based error process method comprises: 1. the optical terminal sends PLOAM message to the optical network unit; 2. the optical network unit processes the received message; 3. the optical network unit generates the response message as results; and 4. the terminal receives response from network, and takes differential process according to the feedback message. This invention avoids error and resource waste led by difference between network terminal and network unit, and improves system reliability and utility.

Description

technical field [0001] The invention relates to the field of access networks, in particular to a method and system for handling errors under the PON PLOAM mechanism. Background technique [0002] At present, in the field of access network, following the full development of DSL, optical access is also booming, especially the point-to-multipoint optical access technology—PON (Passive Optical Network, Passive Optical Network), which has once again attracted attention. Compared with point-to-point optical access, a single optical fiber at the PON central office can be split into dozens or even more user-side optical fibers, greatly reducing network construction costs. Among them, GPON (Gbit Passive Optical Network) is the most comprehensive and mature technology among the current PONs. It is compatible with ATM and IP networks, and has the advantages of high line rate and perfect maintenance and management. [0003] Please refer to Figure 1, the PON system consists of three par...
