(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present application, are given by way of illustration and explanation only, and are not intended to limit the present application.

Fig. 1 is a schematic structural diagram of a GPON system applicable to the embodiment of the present application. As shown in the figure, the GPON System includes an Element Management System (EMS) 101, an OLT 102, an Optical Distribution Network (ODN) device 103, and an ONU 104. The EMS101 is connected with the OLT 102 through a router, and performs information interaction based on a Simple Network Management Protocol (SNMP); the OLT 102 and the ONU 104 are connected through the ODN device 103, and the OLT 102 and the ONU 104 perform information interaction based on the OMCI protocol.

The EMS101 acquires configuration information of an ME instance (abstraction of ONU resources or services) stored by the ONU 104 through the OLT 102 and the ODN device 103, and implements management, maintenance, and the like of a GPON service by a user by analyzing the ME instance configuration information.

The OLT 102 provides an interface between the network side and the core network for the access network, is used for centralized bandwidth allocation, controlling the ONU 104, real-time monitoring, and maintaining the functions of the passive optical network system, and is a core function device in the GPON system.

The ODN device 103 provides an optical transmission channel between the OLT 102 and the ONUs 104, the ONUs 104 provide an interface on the user side for the access network, provide services such as voice, data, and video, and store configuration information of ME instances (ONU resources or abstractions of services), and one ONU 104 corresponds to one GPON service model.

Based on the GPON system structure shown in fig. 1, at the EMS side, a professional manually draws a GPON service model diagram by analyzing OMCI messages one by one to obtain ME instance configuration information, and the drawn GPON service model diagram can visually show the configuration request condition of the GPON service, thereby realizing management, maintenance and the like of the GPON service. However, the GPON service model is complex, the configuration information amount of the ME instance is large, the manual drawing of the GPON service model map is not only high in requirement of professional knowledge but also long in time, and particularly, when real-time operations such as real-time fault location and modification are required, the manual drawing of the GPON service map is long in time, so that the analysis efficiency of the GPON service is reduced, and the method cannot meet the requirement of a user on real-time performance in the GPON service analysis.

In order to solve the above problem, an embodiment of the present application provides a method for implementing visualization of a GPON service model, where an ONU acquires data description information of a GPON service model for describing GPON service configuration information of an ME instance in a text form, and generates a graphical description file of the GPON service model according to the data description information, so that an EMS generates a GPON service model map after acquiring the graphical description file, so as to display the GPON service model map in a graphical manner, and thus, a user can complete real-time acquisition of the GPON service model map by performing a key operation on the EMS, and the efficiency of analyzing the GPON service is improved when the time is short.

As shown in fig. 2, a schematic flow chart of a method for implementing a GPON service model visualization provided in an embodiment of the present application is shown.

As shown, the process includes:

s201: and the ONU acquires the stored data description information of the GPON service model, wherein the data description information of the GPON service model comprises the identification of the ME examples in the GPON service model, the association information between the ME examples and the GPON service configuration information of the ME examples.

The GPON business model is a management information base formed by a plurality of ME instances, and the ONU can obtain attribute information of all the ME instances in the GPON business model by reading pre-stored data description information of the GPON business model. The attribute information of the ME instance includes an identifier of the ME instance, association information with other ME instances, and service configuration information, where if the ME instance is an ME instance related to a GPON service module, the service configuration information at least includes GPON service configuration information. The GPON service configuration information of the ME instance may specifically include a GPON Encapsulation Method (GEM) identifier, service configuration of a bearer (Transmission Container GPON, T-CONT) for carrying a service in the uplink direction of the GPON, and service configuration of a layer two data service, according to configuration information specified in a GPON standard protocol (g.984.3/g.988).

S202: and the ONU generates a graphical description file of the GPON service model according to the data description information of the GPON service model, and the graphical description file of the GPON service model is used for the EMS to draw a GPON service model diagram.

Optionally, in S202, the graphical description file generated by the ONU according to the data description information of the GPON service model is a DOT file. The DOT is a text graphic description language, and the DOT file can be converted into image files with different formats such as png, gif and the like by analyzing the DOT script through a layout engine so as to meet the requirement. The DOT file can describe a directed graph and an undirected graph, and comprises nodes, edges between the nodes and labels, wherein the nodes are used for describing the ME instances, the edges are used for describing the association relationship between the two ME instances, and the labels are used for describing the graphical display information of the nodes and the edges, namely the DOT file can express the content of the nodes and the relationship between the nodes by defining various attributes of the nodes, the edges and the labels.

The graphical display information comprises a display mode of a node corresponding to the ME example and a display mode of an incidence relation with other ME examples. The display modes of the nodes comprise the shapes (such as circles and rectangles), color filling, sizes and the like of the display; the display modes of the association relationship include a display mode of an edge corresponding to the explicit association relationship and a display mode of an edge corresponding to the implicit association relationship, for example, when the two ME instances are in the implicit association relationship, the corresponding edge may be set as a dotted line, otherwise, a solid line with a bidirectional or unidirectional arrow may be used to represent the explicit association relationship of the two ME instances.

Therefore, in the embodiment of the application, the ONU encodes the GPON service model into a DOT file according to the data description information of the GPON service model, so that the EMS parses the DOT file corresponding to the GPON service model into a visual graph of the GPON service model.

Specifically, the ONU converts the data description information of the GPON service model into a DOT file, including: the ONU takes the ME example related to the GPON service model as a node in the DOT file; according to the incidence relation between the ME instances in the GPON service model, the ONU takes the incidence relation between the ME instances and other ME instances as an edge connecting the node and the nodes of other ME instances in the DOT file; and the ONU sets labels (labels) according to the difference of the ME example types and the difference of the incidence relation so as to describe the graphical display information of the nodes and the edges.

The label (label) is used to describe graphical display information of the node and the edge, and the label (label) may be preset, for example, if the ME instance is a root node instance, it is represented by a rectangle; if the ME example is a leaf node example, the ME example is represented by graphs except rectangles such as a circle, a rounded rectangle and the like, namely different ME example types in a plurality of leaf node examples in the GPON service sub-model can be represented by different graphs; if the two ME examples are in implicit association, connecting nodes corresponding to the two ME examples by using a dotted line; if the two ME examples are associated in a display mode, connecting nodes corresponding to the two ME examples by using the solid line edge of the arrow; if the A ME example displays the associated B ME example, the nodes corresponding to the two ME examples are connected by a solid line of a unidirectional arrow in the figure, and the arrow points to the node corresponding to the B ME example, and if the A ME example displays the associated B ME example, and the B ME example also displays the associated A ME example, the nodes corresponding to the two ME examples are connected by a solid line of a bidirectional arrow in the figure.

Based on the predefined tags, taking the generation of the DOT file according to the 5 ME instances constituting the GPON sub-service model as an example, refer to fig. 3, which is a schematic diagram of a GPON sub-service model diagram provided in this embodiment of the present application. As shown, the identifications of the 5 ME instances are ME45_ ox1, ME47_ ox41, ME84_ ox41_ pri3, ME130_ ox1, ME266_ ox1, respectively. In the GPON sub-service model shown in the figure, a DOT file is generated according to the defined tag and the GPON service configuration information of 5 ME instances, so that the EMS generates the GPON sub-service model diagram as shown in fig. 3 according to the DOT file. As shown, according to the defined label, ME45_ ox1 is seen as a root node instance, and the remaining ME instances are leaf node instances; ME84_ ox41_ pri3, ME130_ ox1, ME266_ ox1 are leaf node instances of the same type, ME47_ ox41 are leaf node instances of a different type from ME84_ ox41_ pri3, ME130_ ox1, and ME266_ ox 1; ME47_ ox41 explicitly associates ME45_ ox1 and ME130_ ox1, respectively, implicitly associates ME84_ ox41_ pri 3; ME130_ ox1 and ME266_ ox1 show an association with each other, i.e. ME130_ ox1 shows an association ME266_ ox1, while ME266_ ox1 also shows an association ME130_ ox 1; pbit is 0 … … 7, which means that GPON services with priority attributes 0 to 7 in ME130_ ox1 are all associated with the same ME266_ ox 1.

Optionally, if the acquired data description information of the GPON service model includes the check result stored in S403, the ONU configures the GPON service of the sublink corresponding to the check result as a node of the DOT file, and sets a tag (label) to describe the check result.

It should be noted that the imaging description file may be a DOT file, or a file in other format, as long as it can satisfy the GPON service model that is analyzed as a visualization by the EMS, which is not limited in this application.

S203: and the ONU sends the graphical description file to the EMS.

And the ONU sends the graphical description file to the OLT through the OMCI message, and sends the received graphical description file to the EMS through the SNMP message after the OLT receives the graphical description file.

Because the OMCI protocol specifies that one OMCI message can only load 48 bytes at most, and the size of the graphic description file sent by the ONU to the OLT is usually much larger than the number of bytes, the embodiment of the present application provides a method for uploading a graphic description file.

Fig. 4 is a schematic flow chart of a method for uploading a graphic description file according to an embodiment of the present application.

As shown, the process includes:

s401: and the ONU divides the graphical description file into at least one data segment according to the set window length, wherein each data segment comprises at least one data sheet.

The ONU can segment the graphical description file into at least one data segment according to a set window length (window, assuming that the set window length is N), each complete data segment is composed of N data pieces with equal length, and the N data pieces are assembled to obtain N OMCI messages.

S402: and the ONU sends the graphical description file to the OLT through at least one message so as to send the message to the EMS after passing through the OLT, and each message carries one data slice of the graphical description file.

And the ONU sends a message carrying a data slice in the next data segment after confirming that the first data segment is successfully received according to the receiving confirmation information fed back by the OLT aiming at the last data slice of the first data segment, wherein the first data segment is any one data segment in the graphical description file.

In S402, the ONU uses the OMCI packet as a minimum transmission unit to segment and upload the graphical description file to the OLT, and after the OLT receives all the graphical description files, reports the files to the EMS. And after each time 1 data segment is uploaded to the OLT, the ONU judges whether the data segment is uploaded successfully or not according to a response result (receiving confirmation response) of the OLT to the OMCI message assembled by the last data segment in the currently uploaded data segment, if not, the ONU uploads the data segment to the OLT again, and if so, the ONU uploads the next data segment to the OLT. Therefore, the graphical description file is divided into at least one data segment to be uploaded, the OLT does not need to reply the uploading result of each OMCI message of the ONU, but replies the message to the ONU once after receiving 1 data segment, and the bandwidth utilization rate is improved.

In the above embodiment, the window length may be fixed, and the set window length may be obtained by pre-configuring the ONU by the ONU, or may be obtained by pre-allocating the OLT to the ONU, or may be obtained by pre-negotiating between the ONU and the OLT. On the basis of ensuring that the graphical description file can be successfully sent to the OLT, in order to improve the file transmission efficiency and reasonably utilize channel resources, the embodiment of the application provides a method for adaptively adjusting the window size.

As shown in fig. 5, a schematic flow chart of a method for adaptively adjusting a window length is provided in the embodiment of the present application.

As shown, the process includes:

s501: the OLT adjusts the window length according to the sending state of the current data segment and sends a window adjusting instruction carrying window length adjusting information to the ONU.

The method comprises the steps that an initial value of a window length is configured in advance by an ONU, or the OLT is allocated to the ONU in advance, the ONU divides a graphical description file into data segments according to the initial value of the window length, all the data segments obtained through division are sent to the OLT in an S402 mode, the OLT dynamically adjusts the window length in real time in the data segment receiving process according to the sending state of the data segments, and sends a window adjusting instruction carrying window length adjusting information to the ONU.

The sending state of the data segment can be whether the data segment is uploaded successfully or not, or a bandwidth comparison result, or whether the data segment is uploaded successfully or not and the bandwidth comparison result; the bandwidth comparison result is a comparison result of an occupied bandwidth predicted for transmission of at least one data segment and a bandwidth actually used by the at least one data segment, for example, the predicted bandwidth consumed by the OMCI message transmission channel between the ONU and the OLT for transmitting the graphical description file is W_EThe bandwidth actually allocated to the channel by the OLT is W_aIf the bandwidth comparison result is W-_EW_a。

Taking a GEM in a GPON system as an example, referring to fig. 6, which is a schematic diagram of a GPON encapsulation mode applicable to the embodiment of the present application, in the GPON encapsulation mode, a GEM Port (Port) is a minimum bearer unit of a service, the GEM Port bears service data and is mapped to a T-CONT unit to perform uplink service scheduling in a Dynamic Bandwidth Allocation (DBA) scheduling manner, each ONU supports at least 1T-CONT, and can be configured to different service types, one T-CONT can bear a plurality of GEM ports, and can also bear 1 GEM Port, the T-CONT demodulates the GEM Port after ascending to an OLT side, and then demodulates a service payload in the GEM Port to perform related service processing; as shown in the figure, the three ONUs are ONU1, ONU 2 and ONU 3, ONU1 supports T-CONT 101 and T-CONT 101, ONU 2 supports T-CONT 201, and ONU 3 supports T-CONT 301, where T-CONT 101 carries 3 GEM ports, GEM Port 1, GEM Port 2 and GEM Port 3, T-CONT 201 carries 2 GEM ports, GEM Port 5 and GEM Port 6, T-CONT 102 and T-CONT 301 all carry 1 GEM Port, GEM Port 3 and GEM Port n. Normally, the GEM Port corresponding to the OMCI message shares only one T-CONT, so the bandwidth allocated to the T-CONT by the OLT is actually the bandwidth that can be used by the OMCI message. For example, the transmission path of the OMCI message is: T-CONT 102 → GEM Port 4 → OLT, the current bandwidth allocated to T-CONT 102 on ONU1 by OLT is BandAlloc, and the predicted bandwidth to be actually consumed by T-CONT 102 is BandActual, where the bandwidth comparison result is: BandAlloc/BandActual.

The OLT may adjust the window length according to the sending state of the current data segment, and specifically may include: when the OLT detects that the uploading of the current data segment is failed for the continuous set times, the window length can be reduced; when the OLT detects that the uploading of the data segments with the continuously set number is successful, the window length can be increased or kept unchanged.

The reason why the uploading of the current data segment is failed for the continuously set number of times may be caused by poor link quality, so that the window length needs to be reduced no matter whether the bandwidth allocated by the OLT is sufficient or not, for example, the current window length is directly reduced by half to ensure that the data segment to be uploaded is stably transmitted in the link with poor quality, that is, the reference meaning of the bandwidth comparison result is not great in this case. When the uploading of the data segments with the continuously set number is detected to be successful, the current window length N can be adjusted by combining the bandwidth comparison result, the length of the subsequently uploaded data segment is made larger as much as possible, and the adjusted window length N₁As shown in formula (1):

wherein, N represents the current window length, i.e. the size of each current complete data segment; n is a radical of₁The adjusted window length is the size of each complete data segment; w_E/W_aAs a result of the bandwidth comparison, W_E/W_aThe bandwidth distributed by the OLT to an OMCI message transmission channel between the ONUs is insufficient, but a plurality of continuous data segments are uploaded successfully, namely the OMCI message is not lost in the data segment uploading process, namely the current window length is an ideal value and does not need to be adjusted; w_E/W_aThe bandwidth margin distributed by the OLT to the OMCI message transmission channel between the ONUs is represented by being less than or equal to 1, and the window length can be continuously increased at the moment because the OMCI message is not lost, so that the bandwidth resources are fully utilized, and the data transmission efficiency is improved.

Specifically, in S501, the window length adjustment information issued by the OLT according to the sending status of the current data segment may be determined according to the following manner: if the data segment fails to be uploaded for the continuous set times, the window length adjustment information carried by the window adjustment instruction is the window length reduction; if the data segments with the continuously set number are uploaded successfully and the bandwidth comparison result meets a first condition, window length adjustment information carried by the window adjustment instruction is to keep the window length unchanged; if the data segments with the continuously set number are uploaded successfully and the bandwidth comparison result meets a second condition, window length adjustment information carried by the window adjustment instruction is the increased window length; the first condition is that the predicted occupied bandwidth for the transmission of the at least one data segment is greater than the bandwidth that can be actually used by the at least one data segment, and the second condition is that the predicted occupied bandwidth for the transmission of the at least one data segment is less than or equal to the bandwidth that can be actually used by the at least one data segment.

S502 to S503: and the ONU receives the window adjustment instruction sent by the OLT, re-segments the residual data of the graphical description file according to the window adjustment instruction, and sends the segmented data segment to the OLT.

And after receiving the adjusted window length, the ONU stops the current uploading operation of the data segment, recombines all local data segments to be uploaded, segments the recombined data according to the adjusted window length, and sequentially sends the segmented data segments to the OLT segment by segment.

Based on the flow shown in fig. 5, refer to fig. 7, which is an information interaction diagram for uploading a DOT file in the embodiment of the present application.

As shown, the information interaction graph includes:

s701 to S704: the OLT receives a GPON service model request message sent by the EMS, the OLT carries a window initial value (window length) in the GPON service model request message (S0) and sends the window initial value to the ONU, and the ONU compresses the DOT file after receiving the GPON service model request message and returns a response message carrying the size of the compressed DOT file to the OLT.

S705 to S707: the OLT receives the response message, allocates a memory according to the size of the compressed DOT file, initializes the number total _ num of the data segments which are successfully received to be 0, and sends an uploading request message for requesting uploading of the DOT file to the ONU, after receiving the uploading request message, the ONU segments the DOT file according to S401, each data segment comprises S0 data slices (section), and uploads the data segments to the OLT according to S402.

S708: after the OLT successfully receives the S0 data pieces, the total _ num is increased by 1, and a reception confirmation message is returned to the ONU so that the ONU executes S707; when total _ num is equal to the set value, i.e. the uploading of data segments of the continuously set value is successful, the OLT increases the window length to S1, and S1 is greater than S0.

S709 to S711: the OLT sends a receiving confirmation message carrying S1 to the ONU; after receiving the reception confirmation message, the ONU segments the remaining DOT files according to S1, where each data segment includes S1 data pieces, and uploads the segmented data segments to the OLT according to S402.

S712: when the number of the data pieces successfully received by the OLT is less than S1, the total _ num is set to 0, namely the data segment uploading fails, the OLT reduces the window length to S2, and S2 is less than S1.

S713 to S714: the OLT sends a receiving failure message carrying S2 to the ONU; and after receiving the reception failure message, the ONU segments the remaining DOT files according to S2, wherein each data segment comprises S2 data pieces, and uploads the segmented data segments to the ONT according to S402.

The remaining DOT files are continuously transmitted to the OLT according to the flow shown in S707 to S714, and after the OLT transmits a reception confirmation message for the last data segment of the DOT file to the ONU, the flow shown in S715 to S717 is executed.

S715 to S717: and after receiving the receiving confirmation message about the last data segment of the DOT file, the ONU sends a notification message for confirming the successful uploading of the DOT file to the OLT, and after receiving the notification message, the OLT sends the DOT file to the EMS through an SNMP protocol.

In the above embodiment, the ONU divides the DOT file into a plurality of data segments according to the window length, each data segment includes a plurality of data slices, each data slice corresponds to one OMCI message, and the DOT file is sent to the OLT with the data slice as a transmission unit and the data segment as a reception acknowledgement response unit. In addition, the OLT adjusts the window length according to the sending state of the data segment, reasonably utilizes bandwidth resources and improves the data transmission rate on the basis of ensuring the successful uploading of the DOT file.

Optionally, in fig. 2, the ONU obtains and stores the data description of the locally stored GPON service model to generate a graphical description file that can be analyzed by the EMS as a GPON service model map, so as to implement visualization of the GPON service model. The data description information of the GPON service model may be pre-stored in the ONU in various forms, such as text, table, and the like.

In order to facilitate visual description of the association relationship between ME instances in the GPON service model, in the embodiment of the present application, data description information of the GPON service model is stored in a form of a two-level linked list.

Specifically, the data description information of the GPON service model is stored as a first linked list and a second linked list, and the second linked list includes at least one sub-chain table. The first linked list is used for storing attribute information of the ME examples, the second linked list is used for storing storage positions of the ME examples related to the GPON service model in the first linked list, each sub-chain table corresponds to one GPON service sub-model, and each GPON service sub-model only comprises one root node example.

The data description information of the GPON business model is stored in a form of the two-level linked list, so that the association relation among the ME examples in the GPON business model can be conveniently and visually described.

Fig. 8 is a schematic flow chart of a method for establishing a two-level linked list according to an embodiment of the present application.

As shown, the process includes:

s801 to S802: and the ONU acquires the first ME example and stores the attribute information of the first ME example in a first linked list.

ME instances are stored in memory in the form of a structure (C language) or class (C + + language) and are organized together by a data structure such as a linked list, a tree, etc. In the above step, the ONU traverses the data structure of the first ME instance in the memory to obtain the pointer of the first ME instance, and stores the pointer of the first ME instance in the first linked list.

On the premise that the first ME instance is an ME instance related to a GPON service, steps S803 to S806 are performed.

S803: the ONU judges whether the first ME example is a root node example of the GPON service sub-model or a leaf node example of the GPON service sub-model; if the node is the root node instance, S804 is executed, and if the node is the leaf node instance, S805 is executed.

One ONU corresponds to one GPON service model, one GPON service model consists of one or more GPON service submodels, one GPON service submodel comprises a plurality of ME examples with incidence relations, only one ME example in the plurality of ME examples with the incidence relations is a root node example of the GPON service submodel, and the incidence relations between the ME examples comprise an explicit incidence relation and an implicit incidence relation. Therefore, in S803, the ONU determines, according to the attribute information of the first ME instance, whether the first ME instance is a root node instance of the GPON service sub-model or a leaf node instance of the GPON service sub-model, to determine whether to create a corresponding sublist for the first ME instance. The determination techniques of the root node instance and the leaf and node instances are well known to those skilled in the art and are not described herein again.

S804: and the ONU creates a new sub-chain table in the second linked list, and stores the storage position information of the first ME example in the first linked list in the new sub-chain table, wherein the new sub-chain table corresponds to the GPON service sub-model to which the first ME example belongs.

S805: the ONU judges whether a sublist meeting set conditions exists in the second linked list, wherein the sublist meeting the set conditions is a sublist in which ME instances having an association relation with the first ME instance are stored; if yes, executing S806, otherwise, not updating the second linked list, and ending the process.

The ONU determines whether the plurality of sub-link tables are sub-link tables satisfying a set condition by traversing the plurality of sub-link tables created in the second link table, that is, whether there is an ME instance having an association relationship with the first ME instance among ME instances stored in the plurality of sub-link tables.

S806: and the ONU stores the storage position information of the first ME example in the first linked list and the storage position information of the ME example which has an incidence relation with the first ME example in the first linked list in a sublist meeting the set condition.

Optionally, if a plurality of ME instances having an association relationship with the first ME instance exist in a plurality of sub-chain tables created in the second linked list, on one hand, the ONU stores the storage location information of the first ME instance in the first linked list in the sub-chain table where the ME instances having an association relationship with the first ME instance are located, on the other hand, the ONU acquires the storage location information of the ME instances having an association relationship with the first ME instance in the first linked list, and stores the acquired storage location information in the sub-chain table where the ME instances having an association relationship with the first ME instance are located.

And storing all ME examples obtained by the ONU according to the specific implementation modes related to the S801-S806, and further completing the storage of the data description information of the GPON service model in a form of a two-level linked list. In this case, the ONU may read the nodes of the sub-link tables in the second link table one by one to obtain the storage location information of the ME instance related to the GPON service model in the first link table, and obtain the attribute information of the ME instance related to the GPON service model from the first link table according to the storage location information, thereby completing obtaining the data description information of the GPON service model.

In the above embodiment, the ONU stores the acquired ME instances in the first linked list, which is convenient for the subsequent call and execution of other functional modules, and meanwhile, in order to reduce the memory consumption and avoid copying data many times, the second linked list only stores the storage location information of the ME instances related to the GPON service model in the first linked list, so that the ME instances can be directly indexed into the created first linked list to search for the attribute information of the corresponding ME instances.

Optionally, after the ONU prestores all ME instances in the GPON service model to the first linked list and the second linked list according to the flow shown in fig. 8, in order to determine whether an ME instance under the GPON service configuration in the sub-linked list of the second linked list is complete and whether the configuration is conflicted, before executing S201, ME instance integrity check, service configuration conflict check, or ME instance integrity check and service configuration conflict check may be performed on each sub-linked list in the second linked list.

Fig. 9 is a schematic flow chart of a GPON service configuration detection method provided in the embodiment of the present application.

As shown, the process includes:

s901: and the ONU acquires the GPON service configuration information of the corresponding ME example from the first linked list according to the storage position information of the ME example stored in each sub-linked list in the second linked list.

For each created sub-chain table in the second linked list, the ONU obtains the storage location information of the ME instance stored in each sub-chain table in the first linked list by traversing the ME instance stored in each sub-chain table, and further obtains the GPON service configuration information of the ME instance stored in each sub-chain table.

S902: and the ONU respectively carries out verification processing aiming at the GPON service submodel corresponding to each sublink according to the acquired GPON service configuration information of the ME example, wherein the verification processing comprises at least one of integrity verification and service configuration conflict verification.

In S902, the ONU performs, according to the obtained GPON service configuration information of the ME instance, a check of ME instance integrity on the GPON service sub-model corresponding to each sublink, or a check of service configuration conflict on the GPON service sub-model corresponding to each sublink, or a check of ME instance integrity and service configuration conflict on the GPON service sub-model corresponding to each sublink.

Specifically, the checking of the integrity of the ME instance and the checking of the service configuration conflict may be performed in the following manners:

taking the first sub-link table created in the second linked list as an example, the verification of the integrity of the ME instance includes the following two ways:

the first method is as follows: the ONU compares all ME examples in the first sublink with the key ME examples one by one, for example, compares the ME examples according to the identifications of the ME examples, and judges whether the first sublink lacks a preset key ME example; if not, determining that the ME example of the GPON service submodel corresponding to the first sublink is complete, otherwise, determining that the ME example is incomplete; wherein, one or more of the key ME instances can be preset by those skilled in the art according to technical experience.

The second method comprises the following steps: predefining indication information for configuring GPON service carrying the ME example in the identification of the ME example as a bridge port on an ACCESS NETWORK INTERFACE (ACCESS NETWORK INTERFACE) on the ONU or a bridge port on a USER NETWORK INTERFACE (USER NETWORK INTERFACE) on the ONU; the ONU judges whether an ME example configured by GPON service as an ANI side bridge port and an ME example configured by GPON service as a UNI side bridge port are simultaneously stored in the first sublink list; if yes, determining that the ME example of the GPON service submodel corresponding to the first sublink is complete, otherwise, determining that the ME example is incomplete.

And (3) checking service configuration conflict: the ONU generates a configuration rule according to the GPON service configuration information of the first sub-chain table; the ONU matches the configuration rule with a preset standard configuration rule; if the sub-link tables are matched with each other, determining that the service configuration of the GPON service sub-model corresponding to the first sub-link table is not conflicted, and if the sub-link tables are not matched with each other, conflicted; the ONU generates the configuration rule according to the following form: a GPON service filtering mode, a GPON service filtering rule and an execution action; for example, the configuration rule indicates that only a single tag is allowed, and the traffic flow with vid identification 9 is transmitted through, then the GPON traffic filtering mode is forward _ single tag; the GPON service filtering rule is FILTER SINGLELE TAG, the filterTagMode of the S-TAG is NO CARE, the filterTagMode of the C-TAG is FILTER VID, vid is 9, and EtherType is No Filter; the execution action is transfer.

S903: and the ONU stores prompt information in each sub-chain table respectively, wherein the prompt information is used for describing the verification result of the sub-chain table in which the prompt information is located.

And the ONU stores a verification result of ME instance integrity of the GPON service submodel corresponding to the sublink, or a verification result of service configuration conflict, or a verification result of ME instance integrity and a verification result of service configuration conflict as prompt information to the sublink, namely, the verification result is added to data description information as prompt information of GPON service configuration of the sublink, so that the GPON service configuration condition of the GPON service submodel corresponding to the sublink can be intuitively known according to the prompt information, and further fault positioning is rapidly carried out. And the efficiency of GPON service analysis is improved.

It should be noted that the data description information of the GPON service model may adopt any known GPON service model data description mode other than the linked list, and the linked list storage mode is not limited to the mode described in the above embodiments, as long as the GPON service model can be correctly expressed in the data storage form, which is not limited in this application.

On the EMS side, a user can complete the real-time acquisition of the GPON service model diagram by one-key operation on the EMS, specifically, the EMS acquires the operation information used for displaying the GPON service model diagram of the user, analyzes the operation information, and draws and displays the GPON service model diagram by acquiring the graphical description file of the GPON service model. The following three situations exist in acquiring the graphical description file of the GPON business model:

in the first case: the ONU spontaneously executes S201-S203 according to preset conditions, the EMS locally stores the received graphical description file of the GPON service model, and then the user operation information is analyzed, and a GPON service model graph can be directly drawn and displayed according to the locally stored graphical description file of the GPON service model; the preset condition is defined by the ONU or defined by the OLT and then issued to the ONU, and the preset condition can be set duration, a GPON service model modification request message is received, and the like.

In the second case: the EMS does not locally store the graphical description file of the GPON service model, the EMS analyzes the user operation information and then sends a GPON service model request message to the ONU through the OLT, and then triggers the ONU to execute S201-S203, so that the EMS draws and displays a GPON service model graph according to the graphical description file of the GPON service model sent by the ONU; in addition, since the OLT corresponds to a plurality of ONUs, the GPON service model request message sent by the EMS carries the identifier of one or more ONUs, that is, the EMS may obtain the graphical description file of the GPON service model corresponding to one or more ONUs.

In the third case: the EMS does not locally store the graphical description file of the GPON service model, the EMS analyzes the user operation information and then sends a GPON service model request message to the ONU through the OLT, and then triggers the ONU to execute S203, so that the EMS draws and displays the GPON service model graph according to the graphical description file of the GPON service model sent by the ONU; in this case, the ONU autonomously executes S201 to S202 according to a preset condition, stores the generated graphical description file of the GPON service model locally, and directly transmits the locally stored graphical description file of the GPON service model to the EMS through the OLT after receiving the GPON service model request message transmitted by the EMS.

After S203, the EMS receives the graphical description file sent by the ONU, and by parsing the graphical file, draws a GPON service model map and displays it on a display interface.

Optionally, a modification operation may be performed on a GPON service model map displayed by the EMS, on one hand, the EMS acquires modification information and displays the modified GPON service model map according to the modification information, on the other hand, the EMS sends a GPON service model modification request message to the ONU through the OLT, and the GPON service model modification request message carries the GPON service model modification information, so that after the ONU receives the GPON service model modification request message, the data description information of the GPON service model stored by the ONU is modified according to the GPON service model modification information carried by the GPON service model modification request message, and the modified GPON service model is converted into a configuration for a hardware chip and stored according to the data description information of the modified GPON service model.
