Embodiments of the invention

The embodiments of the present invention are described below in conjunction with the accompanying drawings.

Embodiment 1:

An embodiment of the present invention provides an Ethernet Layer 2 virtual private network service positioning method, and the specific process is shown in FIG. 1 .

Step S101, a service access configuration configures a matrix watershed segment record, and different access modes correspondingly set different connection identification parameter items, and store the identification parameter values of the identification parameter items corresponding to the service into the record, and The matrix watershed segment records form a matrix watershed segment table.

Step S102: For a non-UNI direct-binding VLAN service access, configure a sub-item record, where the sub-item record includes: an identification parameter value of the identification parameter item corresponding to the service, and a VLAN information actually accessed by the service. And record each sub-item to form a sub-item.

Virtual private network VPN is not only a product, but also a service. Virtual private networks establish private data transmission channels through public networks, connecting remote branch offices, business partners, mobile workers, etc., which can reduce the burden of remote access fees, save money, and provide secure end-to-end data communication. the way. The PTN network shown in Figure 4 is taken as an example. As shown in Figure 4, the PTN network includes five PE devices. At a certain time, 10 CE devices access the PTN network. In this step, a matrix watershed segment record is formed for each service access of the CE device to the PE network element device, and all the matrix watershed segment records are formed into a matrix watershed segment table as shown in Table 1 below, and maintained in the system. In the network management, three different access modes corresponding to the CE device accessing the PE network element device are correspondingly set with different connection identification parameter items, and the identification parameter values of the identification parameter items are stored in the matrix watershed segment record, and each will be The slice matrix watershed segment records form a matrix watershed segment table.

Table 1

In practical applications, the identifier field in the matrix watershed fragment identifier, such as "100/101", is unique within the PE device.

The invention provides a description of the three types of access models: the service access model of the UNI directly bound to the VLAN supported by the PE device (such as PE1, PE3, and PE4 in Figure 4); The PE2) supports the UNI binding ClassMap service access model; and the service access model of the UNI sub-interface supported by the latest PE device (such as PE5 in Figure 4). In the three access modes, the service access model of the UNI directly bound to the VLAN supported by the PE device is recorded as the service access of the UNI directly bound to the VLAN, and the UNI supported by the second generation PE device is tied. The service access model of the ClassMap service access model and the service access model of the UNI sub-interface supported by the latest PE device are recorded as service access of the non-UNI directly bound to the VLAN; the following is the specific access mode for the CE device to access the PE network element device. (corresponding to different access models supported by PE devices) for further explanation:

In the service access mode of the UNI directly bound to the VLAN, first select a UNI port, and the user directly sets a VLAN that is not used before the UNI port to bind the UNI port to form an FP (Flow Point). And then accessing a PE network element device to form an MFDFr (Matrix Flow Domain Fragment). For this access Mode, in step S101 of the present invention, after the formation of the MFDFr, a matrix watershed segment record is generated and stored in Table 1, and a matrix watershed segment-flow point record is generated, and the matrix watershed segment shown in Table 2 below is stored. - In the flow point list, as in FP1, FP4 to FP7 in Table 2, the main fields include: FP flow point name, FP flow point parameter, and corresponding FP flow point parameter values. In practical applications, the FP flow point parameter is an access client VLAN or a traffic classification tag.

Table 2

In a service access mode in which a UNI is bound to a complex traffic classifier, the complex traffic classifier module maintains the configuration of the access client VLAN. The UNI port forms a FP by binding with the complex traffic classifier, and then accesses a PE network. Metadevices form an MFDFr. For this access mode, in step S102 of the embodiment of the present invention, after the MFDFr is formed, a matrix watershed segment record is generated and stored in Table 1, and a matrix watershed segment-flow point record is generated and stored in the table. 2, for example, after CE2 and CE3 are connected to PE2, FP2 and FP3 in Table 2 are formed; at the same time, after the UNI binding complex traffic is classified as a non-UNI direct-binding VLAN service access, after CE2 and CE3 are connected to PE2, A complex flow classification record is generated and stored in the complex flow classification table sub-item table as shown in Table 3.

table 3

In the service access mode of the UNI sub-interface, the UNI ports of different PE NEs generate different UNI sub-interfaces according to the VLAN division. Since the sub-interface itself contains VLAN information, an FP is formed and accesses the MFDFr. For this access mode, step S102 of the embodiment of the present invention generates a matrix watershed segment record after the MFDFr is formed, and stores it in Table 1. At the same time, the service access mode of the UNI sub-interface is non-UNI. Bind service access to the VLAN. After CE8, CE9, and CE10 are connected to PE5, a sub-interface record is generated and stored in the sub-interface table sub-item table shown in Table 4.

Table 4

In the actual application, the flow classification identifiers and sub-interface names in Table 3 and Table 4 may be the same or different in the table maintained in each PE device; multiple CE devices under the same PE device may be in the local area network. The mode uses one VLAN value, and can also use one VLAN value separately. The implementation is simple and will not be repeated here.

Step S103: Determine VLAN information to be accessed by the Ethernet Layer 2 virtual private network service.

If a CE is in the state of an Ethernet service alarm, you need to locate the service. The service is the Layer 2 virtual private network service to be located. After querying the engineering operation and maintenance table, the O&M personnel can obtain the VLAN information actually accessed by the CE device. The CE device is configured to access the PE with VLAN=x. For example, the user VLAN=1000 is connected. description.

Step S104: Perform a query in the matrix watershed segment table according to the VLAN information to obtain a first association matrix watershed segment record list.

The matrix watershed segment table is queried to obtain the "actually accessed VLAN information" attribute, and the value VLAN is equal to all the matrix watershed segment records of the VLAN x, and the matrix watershed segment records are put together to form the first associated matrix watershed segment record list. .

As shown in Table 2, when the user VLAN=1000, the FP flow point names that meet the conditions are obtained: FP1, FP4, and FP5, and then matched with the flow list list in Table 1. The first related matrix watershed segment record list is found to include: PE1-100, PE3-100, and PE4-100.

Step S105, querying all the child item tables according to the VLAN information to obtain a first related child item record list, and performing query in all matrix watershed segment tables according to the identification parameter values in the first associated child item record list. Two association matrix watershed segment record list.

Query all the child entries to obtain the VLAN information attribute of the actual access, and the value VLAN is equal to all the child records of VLAN x. These child records are put together to obtain the first associated child record list. Then, according to the identification parameter in the first associated child record list, the same identification parameter is queried in all matrix watershed segment tables to obtain a second association matrix watershed segment record list.

As shown in Table 3, when the user VLAN=1000, the service whose traffic classifier is PE2-B is found, and then the traffic classifier FP3 whose traffic classifier is PE2-B is found in Table 2, and then with Table 1. Matching through the flow point list to obtain the service PE2-101;

As shown in Table 4, when the user VLAN is 1000, the matching of the sub-interface name is PE5-SIP8, and then the service in the flow-point list is PE5-SIP8 is PE5-100.

Therefore, the second association matrix watershed segment record list found in this step includes: PE2-101 and PE5-100.

In step S106, the first association matrix watershed segment record list and the second association matrix watershed segment record record list are merged, and the Ethernet Layer 2 virtual private network service is to be located and located in the merged record list.

The first associated matrix watershed segment record list obtained in step S104 and the second associated matrix watershed segment record list obtained in step S105 are combined to form a record list. The operation list is output to the terminal operation and maintenance personnel. The operation and maintenance personnel locate and locate the Ethernet Layer 2 virtual private network service based on the result.

Following the above steps, the list of records merged in this step includes: PE1-100, PE3-100, PE4-100, PE2-101, and PE5-100.

The Ethernet Layer 2 virtual private network service positioning method provided by the embodiment of the present invention determines that the Ethernet layer to be located is determined by storing the service access and the corresponding identification parameter items in the matrix watershed segment table and the child item table. The VLAN information of the virtual private network service is queried to obtain the association matrix watershed segment record list, and the Ethernet layer 2 virtual private network service is to be located for the location check, and the VLAN information obtained when the CE access device has a service alarm quickly locates the related service. For troubleshooting and business recovery.

Obviously, those skilled in the art should understand that one of the first association matrix watershed segment record list, the first associated child record list, and the second associated matrix watershed segment list may be empty, but does not affect the next steps. . If the solution of the embodiment of the present invention is applied to another scenario, corresponding changes to the content of the solution should also be considered as belonging to the protection scope of the present invention.

Embodiment 2:

An embodiment of the present invention provides an Ethernet Layer 2 virtual private network service positioning method, and the specific process is shown in FIG. 2 .

Step S201, configuring a matrix watershed segment table and a sub-item table.

A matrix watershed segment record is configured for each service access to form a matrix watershed segment table. Different access methods correspond to different identification parameter items, and the identification parameter values of the identification parameter items corresponding to each service are stored in the matrix watershed segment records of the service, as shown in Table 1 and Table 2.

For each non-UNI direct-binding VLAN service access, that is, the UNI is bound to the service access of the complex traffic classifier and the service access of the UNI sub-interface, a sub-item record is configured. For the service access of the UNI bound to the complex traffic classifier, the configured sub-item records include: the actual access VLAN information, the PE network element information, and the traffic classifier tag of the service access. For the service access of the UNI sub-interface, the configured sub-item records include: the actual access VLAN information and sub-interface name. These sub-items are grouped into a sub-item table, as shown in Tables 3 and 4.

Step S202: Determine all PE devices connected to the CE device to which the Ethernet Layer 2 virtual private network service belongs.

An Ethernet service alarm is generated on the CE1 device. The service is the Layer 2 virtual private network service. The CE device to which the positioning service belongs is the CE1 device. All the PE devices connected to it are PE1 devices.

In step S203, the matrix watershed segment table and/or the sub-item table managed by all the PE devices are used as the query range of the VLAN information to be accessed by the Ethernet Layer 2 virtual private network service.

From Table 1, Table 2, Table 3, and Table 4, all the attributes of the PE NE information are "PE1". All the matrix watershed segment records and sub-item records are extracted to form a query range of VLAN information to be accessed by the Ethernet Layer 2 virtual private network service. The query scope is shown in Table 5 and Table 6. Table 5 is the matrix watershed segment table composed of all matrix watershed segment records whose PE network element information attribute is PE1, and Table 6 is the matrix watershed of all FPs whose PE network element information attribute is PE1. Fragment-flow point list, since Table 3 and Table 4 do not refer to the FP whose PE network element information attribute is PE1, it is directly excluded.

table 5

Table 6

Step S204: Determine VLAN information to be accessed by the Ethernet Layer 2 virtual private network service.

The CE device to which the Ethernet Layer 2 virtual private network service belongs is determined to be the CE1 device. The VLAN ID of the VLAN is 1000.

Step S205: Querying, according to the VLAN information, the matrix watershed segment table in the query range of the VLAN information to be accessed by the Ethernet Layer 2 virtual private network service to obtain the first association matrix watershed segment record list.

In Table 6, the query is performed to obtain the "actually accessed VLAN information" attribute, and all the matrix watershed segments whose value is equal to 1000 are recorded as FP1, and the corresponding matrix watershed segment records are queried from Table 5 by "FP1". The associated matrix watershed segment record list is FP1.

Step S206, querying all the child items according to the VLAN information to obtain a first associated child record list.

According to the "actually accessed VLAN information" attribute and the value VLAN is equal to 1000, the first associated child record list is obtained from Table 3 and Table 4, and is empty at this time.

Step S207, querying all the matrix watershed segment tables according to the identification parameters in the first associated child record list to obtain a second association matrix watershed segment record list.

Since the first associated child record list is empty, the second associated matrix watershed segment record list is also empty.

Step S208, the first associated matrix watershed segment record list and the second associated matrix watershed segment record list are merged into a record list.

The first associated matrix watershed segment record list (Table 5) and the second associated matrix watershed segment record list (which is empty) are merged into a record list, as shown in Table 7.

Table 7

In step S209, the Ethernet Layer 2 virtual private network service is to be located in the record list for location and troubleshooting.

The O&M personnel performs the locating check according to the record list (Table 7), finds the matrix watershed segment corresponding to the service in which the CE1 device has an alarm, and finally repairs the service alarm.

The Ethernet Layer 2 virtual private network service positioning method provided by the embodiment of the present invention can adapt to various complex VLAN access modes, and encapsulates the complexity into the internal, presenting a simple interface to the user, requiring only user input. The VLAN value and/or PE network element to be queried can quickly locate the corresponding matrix watershed segment and return the result.

Obviously, those skilled in the art should understand that the S200 and S203 can determine that the query range of the VLAN information to be accessed by the Ethernet Layer 2 virtual private network service can be located at the end, in order to further narrow the query range. If the solution of the embodiment of the present invention is applied to another scenario, corresponding changes to the content of the solution should also be considered as belonging to the protection scope of the present invention.

Embodiment 3:

An embodiment of the present invention provides an Ethernet Layer 2 virtual private network service positioning device. For a specific schematic diagram, refer to FIG. 3. The following further describes each module and function, including a first configuration module 301, a storage module 302, a second configuration module 303, a first determination module 304, a first query module 305, a second query module 306, and a third query module. 307, a merge module 308, a location troubleshooting module 309, in,

The first configuration module 301 is configured to: configure a matrix watershed segment record for each service access, and different access modes correspondingly set different connection identification parameter items, and the storage module 302 identifies the identification parameter value of the identification parameter item corresponding to the service. The data is stored in the matrix watershed segment record, and each matrix watershed segment record is stored in the matrix watershed segment table.

The first configuration module 301 in the virtual private network is configured to: configure a matrix watershed segment record for each service access of the CE device to access the PE network element device. The three different access modes corresponding to the CE device accessing the PE network element device are configured to set different connection identification parameter items, and the storage module 302 stores the identification parameter value of the identification parameter item in the matrix watershed segment record, and Each matrix watershed segment record is stored in the matrix watershed segment table. The following describes the specific access mode of the CE device to access the PE network element device:

The UNI is directly bound to the service access of the VLAN. First, a UNI port is selected. The user directly sets a VLAN that is not used before the UNI port to bind the UNI port to form an FP, and then accesses a PE network. Metadevices form an MFDFr. After the MFDFr is formed, the first configuration module 301 generates a matrix watershed segment record, and the storage module 302 stores it in the matrix watershed segment table. The identification parameter item includes a matrix watershed segment identifier, a belonging PE network element, and a flow point list. The matrix watershed segment identifier stores the service name of the generated matrix watershed segment, and the belonging PE network element stores the ID of the access PE network element. The flow point list entry stores the FP name generated after the UNI port is bound to the VLAN. As shown in Table 1, for example, FP1 is a FP1 formed by the service that the UNI is directly bound to the VLAN, and is connected to the PE network element device PE1.

The storage module 302 is configured to: store the actual VLAN information of the service that the UNI directly binds to the VLAN as the identification parameter value of the identification parameter item into the matrix watershed segment record. As shown in Table 2, the matrix watershed segment table lists the values of the generated FP name, FP flow point parameters, and FP flow point parameters. For example, the FP1 and the FP1 are configured by the UNI and the FP1. The FP flow point parameter corresponding to the FP1 is the value of the VLAN and the FP flow point parameter set by the user. In the present embodiment, the matrix watershed segment table is divided into Table 1 and Table 2 for convenience of explanation, and actually Table 1 and Table 2 may be one list.

The UNI is bound to a complex traffic classifier. The complex traffic classifier maintains the configuration of the access client VLAN. The UNI port is bound to the complex traffic classifier to form an FP and then accesses a PE network element device. Form an MFDFr. After the formation of this MFDFr, the first The configuration module 301 generates a matrix watershed segment record, and the storage module 302 stores it in the matrix watershed segment table. The storage module 302 stores the value of the traffic classifier tag of the service access of the UNI binding complex traffic classifier as the identification parameter value of the identification parameter item in the matrix watershed segment record. As shown in Table 1, for example, FP2 is a FP2 formed by the service of the UNI bound complex traffic class, and is connected to the PE network element device PE1. As shown in Table 2, the FP flow point parameter of FP2 is the traffic classifier tag, which is the name of the traffic classifier to which the previous user selects the UNI port, such as the traffic classifier A.

In the service access of the UNI sub-interface, different UNI sub-interfaces are generated for the UNI ports of different PE NEs according to the VLAN division. Since the sub-interface itself contains VLAN information, an FP is formed and accesses the MFDFr. After the MFDFr is formed, the first configuration module 301 generates a matrix watershed segment record, and the storage module 302 stores it in the matrix watershed segment table. The storage module 302 stores the value of the sub-interface name of the service access of the UNI sub-interface as the identification parameter value of the identification parameter item in the matrix watershed segment record. The actual access VLAN information is reflected in the sub-interface itself. Therefore, the VLAN information actually accessed by the service access of the UNI sub-interface is not stored in Table 2. As shown in Table 1, FP3 is the FP3 formed by the service of the UNI sub-interface and is connected to the PE network element device PE1.

The second configuration module 303 is configured to: configure a sub-item record for each non-UNI direct-binding VLAN service access. The sub-item record includes: an identification parameter value of the identification parameter item corresponding to the service, and VLAN information actually accessed by the service. The storage module 302 stores each of the sub-item records in the sub-item table.

For the service access of the UNI bound to the complex traffic classifier, the configured sub-item records include: the actual access VLAN information, the PE network element information, and the traffic classifier tag of the service access. The table of complex flow classification data sub-items is shown in Table 3. In actual application, you can configure some VLAN access information data in the functional area of the complex traffic classifier. Configure the traffic classifiers for different PE NEs according to their needs. The traffic classifier tag column of the service access class stores the traffic classifier. The name of the PE network element information column indicates which PE network element the traffic class name corresponds to. The traffic classifier name only needs to be unique within the network element. The actual access VLAN information column represents the VLAN value bound to the traffic class name. . After the complex traffic classification module is maintained, the user can bind the traffic classification name by selecting the UNI port.

For the service access of the UNI sub-interface, the configured sub-item records include: the actual access VLAN information and sub-interface name. The value of the sub-interface name contains the information about the PE network element to which it belongs, so The information about the PEs to which the UNI sub-interface is bound is displayed. For example, as shown in Table 4, the sub-interface 1 is connected to the PE1 device, and the VLAN information actually accessed is 1003.

The first determining module 304 is configured to: determine VLAN information to be accessed by the Ethernet Layer 2 virtual private network service.

When an Ethernet device has an Ethernet service alarm, the service needs to be located. The service is the Layer 2 virtual private network service to be located. After querying the engineering operation and maintenance table, the first determining module 304 can determine the VLAN information that the CE alarm device actually accesses, that is, the VLAN information to be accessed by the Ethernet Layer 2 virtual private network service. It is now set that the CE device is connected to the PE by VLAN x.

Based on the VLAN information determined by the first determining module 304, the first query module 305 is configured to perform a query in all the matrix watershed segment tables stored in the storage module 302 to obtain a first associated matrix watershed segment record list.

The matrix watershed segment table stored in the storage module 302 is queried to obtain the "actually accessed VLAN information" attribute and all the matrix watershed segment records whose value VLAN is equal to x, and the matrix watershed segment records are put together to form the first association matrix. A list of watershed segment records.

According to the VLAN information determined by the first determining module, the second query module 306 is configured to: perform a query in all the child items to obtain a first associated child record list, and according to the identification parameter value in the first associated child record list, The third query module 307 performs a query in all the matrix watershed segment tables to obtain a second association matrix watershed segment record list.

The second query module 306 queries all the child items to obtain the VLAN information attribute of the actual access and takes all the child records of the VLAN equal to x, and puts these child records together to obtain the first associated child record list. The third query module 307 further queries the same identification parameter in all the matrix watershed segment tables according to the identification parameters in the first associated child record list to obtain a second association matrix watershed segment record list.

The merging module 308 is configured to combine the first associated matrix watershed segment record list and the associated matrix watershed segment record list to generate a record list.

The first query module 305 obtains the first associated matrix watershed segment record list and the third query module 307 obtains the second associated matrix watershed segment record list attribute column, and the merge module 308 combines them to generate a record list.

The locating check module 309 is configured to perform positioning and locating the Ethernet Layer 2 virtual private network service in the record list generated by the merging module 308.

The locating check module 309 locates the matrix watershed segment corresponding to the Ethernet layer 2 virtual private network service to be located according to the record list.

In an exemplary embodiment, the Ethernet Layer 2 virtual private network service locating device in this embodiment may further include:

The second determining module 310 is configured to: determine all PE devices connected to the CE device to which the Ethernet Layer 2 virtual private network service to be located belongs;

The third determining module 311 determines, according to the matrix watershed segment table and/or the sub-item table stored by the storage module 302 that is determined by the second determining module 310, the VLAN to be located for the Ethernet Layer 2 virtual private network service to be located. The scope of the query.

The third determining module 311 may determine, by the second determining module 310, all the PE devices connected to the CE device to which the Ethernet Layer 2 virtual private network service belongs, and the third determining module 311 may store the matrix watershed segment table and/or the child table from the storage module 302. The query range of the VLAN information to be accessed by the Ethernet Layer 2 virtual private network service is further determined, and the query range of the first query module 305 and the second query module 306 is narrowed.

The Ethernet Layer 2 virtual private network service locating device provided by the embodiment of the present invention determines the to-be-located Layer 2 virtual private network service by configuring the service access and the corresponding identification parameter item and storing the data in the matrix domain segment table and the child item table.
