Description

Debugging method and device for intercommunication OMCI (OMCI) messages of GPON (gigabit passive optical network) system
Technical Field
The invention relates to the technical field of OMCI protocol management of a GPON system, in particular to a debugging method and a debugging device for OMCI message intercommunication of the GPON system.
Background
The GPON (Gigabit-Capable Passive Optical Networks) technology is a broadband Passive Optical integrated access standard based on ITU g.984.x standard, and is a mainstream broadband access technology at present. The omci (ONU Management and control interface) is an information interaction protocol defined in ITU g.984.4 standard, and is used for OLT Management of ONUs in a GPON network, including configuration Management, fault Management, performance Management, security Management, and the like. The ITU G.984.4 standard defines an OMCI management interface to comprise an OLT and an ONU various message encoding formats and a message interaction process, and in order to meet the GPON new function requirement, the ITU G.988 standard revises and expands the G.984 standard.
Although the ITU has detailed definitions of the OMCI protocol, due to the complexity of the OMCI protocol itself and the ambiguity in description of some technical details of the relevant protocol, there is a deviation in the standard understanding between equipment vendors, which causes difficulties in the interworking between the OLT and the ONU; in addition, when the functions required by the OLT are not defined in the OMCI protocol standard ITU g.984 or ITU g.988, the OLT vendor may extend the OMCI management entity, even over an existing management entity, which prevents the OLT from interworking with third party vendors ONUs. For the ONU, the ONU can be normally used only through the intercommunication and the butt joint of the OLT, otherwise, the ONU can not normally open the service.
In use of the ONUs, a plurality of OLT manufacturers need to be docked, and often, the software versions of the OLTs in different regions of one OLT manufacturer are different, and even the software versions of the same OLT in different periods may be different, which leads to frequent demands of the ONUs for intercommunicating and docking the OLTs. Due to the difference of processing of an OLT manufacturer on an OMCI protocol, an OMCI message of a third-party ONU which is successfully connected with the OLT needs to be captured for analysis, and due to the fact that the captured OMCI message is in a hexadecimal format and the complexity of the OMCI protocol, readability is poor, analysis efficiency is low, and errors are prone to occurring.

Example one
Fig. 1 is a flowchart illustrating a method for debugging an OMCI message communicated by a GPON system according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a method for debugging an OMCI message interworking with a GPON system, where the method includes:
step 1: and preprocessing the OMCI message, storing the preprocessed OMCI message in a text file, and obtaining an OMCI message text which is effective net storage of 48 bytes.
Specifically, the OLT is an access end device, the number is large, the distribution is wide, a plurality of manufacturers exist, frequent intercommunication and docking requirements exist between the ONUs and the OLT, and each modification of the intercommunication between the ONUs and the OLT requires that the ONUs hang under the OLT to capture an OMCI interaction message, and the correctness of the modification is analyzed and confirmed. The difference of the OLT manufacturer to the OMCI protocol understanding and the expansion of the OMCI protocol need to capture and analyze the OMCI message of the third-party ONU which meets the OLT intercommunication requirement. The OMCI message captured by the aid of equipment such as a GPON analyzer is in a hexadecimal format, readability is extremely poor, manual interpretation needs to be carried out according to OMCI protocol standards, work is time-consuming, errors are prone to occurring, and differences of OMCI cannot be located quickly. If the OMCI message of any ONU can be simulated and analyzed on the ONU, the understanding deviation and the expansion of an OLT manufacturer to the OMCI protocol can be quickly identified, the correctness of OMCI modification of each time of simulation debugging can be realized, and the intercommunication debugging requirements of arranging personnel to the corresponding OLT for butting the ONU can be reduced.
If the simulated OMCI message has redundancy, the preprocessing is to store the clean kernel only retaining 48 bytes after the OMCI message is processed as a text file, as shown in the following table 1:
Figure BDA0002389253100000101
TABLE 1
Step 2: and uploading the OMCI message text to the ONU, and operating an OMCI program of the ONU, wherein the OMCI program comprises a debugging thread and an analysis module, and the OMCI message text is read by the debugging thread and is sent to the OMCI program one by one.
Furthermore, the interface for sending the OMCI message text by the debugging thread is consistent with the OMCI message interface for receiving the OLT OMCI message by the OMCI program.
Specifically, an OMCI message text file is uploaded to an ONU, a debugging thread is added to an OMCI program, the OMCI messages are read by the debugging thread and sent to the OMCI program for processing one by one, and the messages are sent to the OMCI program through an interface for receiving OLT messages, namely, a message sending interface is consistent with an OMCI message receiving interface of the OMCI program.
And step 3: and analyzing the OMCI message text through the analysis module to obtain an analysis result and store the analysis result in an LOG file.
Further, the analyzing the OMCI message text by the analyzing module to obtain an analysis result, and storing the analysis result in a LOG file includes: analyzing the received OMCI message text item by item according to an OMCI protocol standard and an OMCI program ME library, wherein the OMCI message text item comprises a message identifier, a message type, an equipment identifier, a message identifier and message content; when the OMCI message text is a message from the ONU to the OLT, only the OMCI message is analyzed and no response processing is carried out, and an analysis result is stored in an LOG file; and when the OMCI message text is a message from the OLT to the ONU, analyzing the OMCI message and performing response processing, and storing analysis combination and response information in an LOG file.
Specifically, the OMCI program adds an OMCI message parsing module to parse the received OMCI message text according to the OMCI protocol standard and an OMCI program ME library, and parse all the clean cores of each OMCI message, such as a message identifier, a message type, a device identifier, a message identifier, and message content. And the OMCI program analysis module only analyzes the message in the direction from the ONU to the OLT and does not perform response processing, and records the analysis result into the LOG file. For OMCI message text in the direction from the OLT to the ONU, an OMCI program analyzes and responds, the message is responded according to the flow when the OLT is normally butted, the received OMCI message is analyzed and recorded in an LOG file according to an OMCI protocol standard and an OMCI program ME library, the OMCI message type, an equipment identifier, a message identifier, an ME ID, an ME name, an ME instance number, an ME attribute mask and an ME attribute value are analyzed, the response message is also analyzed and recorded in the LOG file, and the unsupported ME ID, the ME instance number, the ME attribute and the ME behavior are recorded in the LOG file. The basis of OMCI message analysis by the OMCI program is an ME library supported by the OMCI program, namely an OMCI ME capability set supported by the ONU.
And 4, step 4: and obtaining a non-supported message according to the LOG file, wherein the non-supported message is a message of an ME ID, an ME example number, an ME attribute value and an ME behavior which are not supported.
Further, the LOG file includes an ME ID, an ME instance number, an ME attribute value, and an ME behavior, which are not supported.
Specifically, the ME ID, ME instance number, ME attribute, and ME behavior that are not supported in the ONU ME library are recorded in the LOG file, and it is possible to know which ME ID, ME instance number, ME attribute, and ME behavior are not supported by analyzing the LOG file.
And 5: and responding the message which is not supported, modifying the OMCI program, and repeating the step 2-4 until all the messages which are not supported are processed.
Further, the responding the unsupported message and modifying the OMCI program includes: and responding the unsupported message according to a method of OMCI message text in the direction from the ONU to the OLT, and modifying the OMCI program according to an analysis result of the OMCI message text in the direction from the ONU to the OLT.
Specifically, by analyzing the LOG file, it can be known which ME ID, ME instance number, ME attribute, ME behavior are not supported. For response of an ME ID, an ME instance number, an ME attribute and an ME behavior which are not supported, the response can be made by referring to an OMCI message of a third-party ONU from the ONU to the OLT. By analyzing the LOG file, the simulation debugging process is repeated after the OMCI program is modified until the OMCI program processes a message without processing failure, the intercommunication problem is solved, and the OMCI message of any ONU is simulated and analyzed on the ONU, so that the understanding deviation and the expansion of an OLT manufacturer to the OMCI protocol can be quickly identified, the correctness of OMCI modification at each time of simulation debugging is realized, and the intercommunication debugging requirements of arrangement personnel to the ONU under the corresponding OLT are reduced. The method realizes the simulation and analysis of the OMCI message in the hexadecimal format through the OMCI program, can verify the intercommunication between the ONU and the OLT at any time without being limited by OLT hardware, effectively saves the human resource expenditure and the hardware expenditure, can quickly analyze the OMCI message of the third-party ONU, and identifies which ME IDs, ME example numbers, ME attributes and ME behaviors are not supported, which ME processes have differences, thereby greatly improving the efficiency of solving the intercommunication problem of the ONU.
Further, before the parsing the OMCI message text by the parsing module, the method includes: and carrying out legality verification on the received OMCI message text through an OMCI program to obtain a verification result, and when the verification result fails, not carrying out subsequent analysis and response on the OMCI message text.
Further, the length of the OMCI message text is 48 bytes, and the devicedentifier in the OMCI message text is 0x 0A.
Specifically, after the OMCI message text is sent to the OMCI program through the interface for receiving the OLT message, the OMCI program performs validity check on the received message, the length of the message needs to be 48 bytes, the Device identifier in the message is 0x0A, and if the message fails to meet the requirement, the message which fails in the check does not perform subsequent analysis and response, so that the interoperability is ensured.
