Problems solved by technology

It is used to solve the problem that some messages cannot be captured by traditional mirroring methods because they are only processed between the CPU and the PON chip without passing through the switching chip.

Embodiment 1

[0096] This embodiment provides a PON system message mirroring method, which can be executed by the OLT equipment in the system, see image 3 , including the following steps:

[0097] Step 301, the PON chip of the OLT copies the PON message exchanged between the OLT and the ONU.

[0098]In this embodiment of the present invention, mirroring includes uplink mirroring and / or downlink mirroring. Correspondingly, in this step, the PON message exchanged between the OLT and the ONU includes: an uplink PON message reported by the ONU to the OLT, and / or a downlink PON message sent by the OLT to the ONU. Wherein, the PON message includes a management message of the PON protocol (such as a registration message, an OAM message, etc.) and a service message. During specific implementation, the OLT can capture and copy the PON messages interacting with the ONU on the user side interface (PON port of the PON chip). If the downlink message is mirrored, the copied message is processed by the...

Embodiment 2

[0117] In the first embodiment above, all PON packets sent and received by the user-side interface of the central office will be sent to the main control CPU through the mirror channel for grouping and forwarding, which will greatly increase the processing burden of the main control CPU. For this reason, this embodiment is improved on the basis of the foregoing embodiments, so as to alleviate the disadvantage of heavy load on the main control CPU caused by the processing of mirrored packets. see Figure 5 , the present embodiment provides a PON system message mirroring method, the method can be executed by the OLT equipment in the system, specifically including the following steps:

[0118] Step 501, the PON chip of the OLT copies the PON message exchanged between the OLT and the ONU.

[0119] Step 502, the PON chip of the OLT performs image compression processing on the copied PON message.

[0120] Wherein, the image compression processing strategy may be preset by those sk...

Embodiment 3

[0142] see Figure 7 , the present embodiment provides a PON system message mirroring method, the method is applied to the GPON system, is executed by the OLT equipment in the system, and specifically includes the following steps:

[0143] Step 701, the PON chip of the OLT copies the PON message exchanged between the OLT and the ONU.

[0144] In step 702, the PON chip of the OLT identifies the messages belonging to the preset second specific category among the copied PON messages.

[0145] In this step, the preset second specific type of messages can be divided into the following subtypes of messages: uplink messages managed by the same PON chip, uplink mixed high-burst messages on a single PON port, single PON port Downlink high burst packets.

[0146] In PON systems, see Figure 8 , the PON board of the OLT is provided with a switch chip, at least one PON chip and multiple PON ports; further, each PON chip of the OLT contains at least one CPU, and different CPUs in the PO...

Abstract

The invention discloses a message mirroring method of PON system, and the PON system. The method is applied to an OLT in the system, and comprises the following steps: copying a PON message of interaction between the OLT and an ONU; repackaging the copied message to obtain a message in a virtual local area network (VLAN) frame format; and outputting the message in the VLAN frame format to a peripheral. Therefore, the problem that a part of messages cannot be captured in a traditional mirroring mode is solved, various PON messages of interaction between the OLT and the ONU in the system can be captured, output and printed, and the fault problem of an ODN link side of a local side and a terminal device in the PON system can be positioned in an auxiliary mode.

Description

technical field [0001] The invention relates to the technical field of optical networks, in particular to a PON system message mirroring method and a PON system. Background technique [0002] PON (Passive Optical Network, Passive Optical Network) technology is a point-to-multipoint optical fiber access technology, which consists of OLT (Optical Line Terminal, optical line terminal, also known as central Optical Network Unit, optical network unit, also known as terminal equipment) and ODN (Optical Distribution Network, optical distribution network). Passive means that the ODN does not contain any active electronic devices and electronic power sources, and all of them are composed of passive devices such as optical splitters. PON is a pure media network, which avoids the electromagnetic interference and lightning effects of external equipment, reduces the failure rate of lines and external equipment, improves system reliability, and saves maintenance costs. It is a long-await...
