Embodiment 1

[0061] In this embodiment, the trigger condition is: when the OLT performs the encryption mode switching operation, the OLT initiates an encryption mode switching request to the ONU, and does not receive a confirmation message returned by the ONU. The processing flow of the method in this embodiment includes the following steps:

[0062] Step 201, the OLT actively initiates a request for encryption mode consistency detection, and sends a request message encapsulated with the current encryption mode to the ONU. The request message can be sent multiple times, such as three times, and the OLT waits for the ONU to respond to the sent request message and confirm.

[0063] Step 202: After receiving the request message, the ONU reads the current encryption mode locally stored on the ONU side, encapsulates the current encryption mode into a confirmation message and returns it to the OLT. The confirmation message may also be sent multiple times, such as three times.

[0064] Step 203...

Embodiment 2

[0076] In the case that the trigger condition is further initiated by the network element management system, that is to say, the trigger condition is initiated by the network management and maintenance personnel from the network element management system, and the OLT initiates the consistency check of the current encryption mode actively. The method flow in this embodiment includes steps 301 to 308, wherein step 305, step 307, and step 308 are different from the method flow in the first embodiment, and the processing of other steps is the same.

[0077] Step 305. Here, because the consistency detection fails, the OLT executes processing for the consistency detection failure, and ends the current consistency detection processing flow.

[0078] Wherein, after the consistency detection fails in step 305, step 305 further includes: the OLT reports the failure of the consistency detection to the network element management system.

[0079] Step 307. Here, since the comparison result...

Embodiment 3

[0084] In the case that the trigger condition is further triggered by the OLT periodically, that is to say, according to the trigger condition, the OLT periodically initiates the consistency detection of the current encryption mode, the method flow of this embodiment includes steps 401-408, Wherein, step 405, step 407, and step 408 are different from the method flow in the first embodiment, and the processing of other steps is the same.

[0085] Step 405. Here, because the consistency detection fails, the OLT executes processing for the consistency detection failure, and ends the current consistency detection processing flow.

[0086] Wherein, after the consistency detection fails in step 405, step 405 further includes: the OLT sends to the network element management system an alarm message that the consistency detection of the current encryption mode related to the ONU fails; the network element management system performs further processing according to the alarm message.

Abstract

The invention discloses an encrypting mode coherence detecting method of a GPON system, comprising: initiating the encrypting mode coherence detecting request by OLT, and transmitting the request information for inquiring the housed current encrypting mode to ONU; reading the current encrypting mode stored in the local on ONU side by ONU, and housing the encrypting mode to the confirmation message, returning to OLT; judging whether receiving the returned confirmation message by ONU by OLT, if not, executing the process aiming at the failure of coherence detection, if true, resolving the current encrypting mode, compared with current encrypting mode stored on the OLT side, performing the corresponding process according to the different comparing result, taking the remedial action in time, and performing the corresponding process.

Description

technical field [0001] The invention relates to a consistency detection technology, in particular to a consistency detection method of an encryption mode in a G-bit passive optical network (GPON, Gigabit Passive Optical Network) system. Background technique [0002] The GPON system is a new generation of broadband passive optical integrated access technology based on the ITU-T G.984.x standard. Usually, the network element equipment in the GPON system includes: the optical line terminal (OLT, Optical Line Terminal) on the office side, the optical Distribution network (ODN, Optical Distribution Network), user-side optical network unit (ONU, Optical Network Unit) and optical network terminal (ONT, Optical Network Termination). The OLT can be connected to the ONU via the ODN to form a GPON system, and can also be connected to the ONT via the ODN to form a GPON system. [0003] Among them, the network element devices in the GPON system are interconnected using a point-to-multip...
