Embodiment 1

Please refer to FIG. 1 , which is a flowchart of a method for displaying a service path in network fault maintenance according to Embodiment 1 of the present invention. The method for displaying the service path in the network fault maintenance may be applied to a terminal running a predetermined program, where the method for displaying the service path in the network fault maintenance may include: Step 101: Obtain object information of two objects, where the object is in the network a physical network element or a virtual network element that includes part of the object information of the physical network element;

The terminal may first acquire object information of two objects input by the user. The "object" in this document can refer to the physical network element that actually exists in the network. It can also be a virtual network element that does not exist and only uses part of the object information of the physical network element. When you need to find the business path between two objects, you first need to provide the object information of the two objects. The object information may be any one of a network element name, a network element interface name, a network element interface IP address, a loopback address of the network element, and a management IP address of the network element.

Step 102: Search for a service path between the two objects according to the object information, where the service path is an asynchronous transmission mode service, a time division multiplexing service, or a network element and a link through which the Ethernet service passes.

After the terminal obtains the object information of the two objects input by the user, the terminal can find the service path between the two objects according to the object information. The service path is the network element and link through which the two-object asynchronous transmission mode service, time division multiplexing service, or Ethernet service passes. For example, if the object information is the IP address of the network element interface, the terminal can query the corresponding routing forwarding table according to the IP address, and then gradually find the service path corresponding to the Ethernet service between the two objects according to the forwarding information.

Step 103: Display network elements and links on the service path between the two objects. In the process of the terminal searching for the service path between the two objects, each time a network element or a link on the service path is found, the user can be displayed in real time.

In summary, the display method of the service path in the network fault maintenance provided by the embodiment is to find and visually display the service path according to the object information provided by the user, and the process of finding the service path mainly relies on the personal skill of the maintenance engineer. The level of the problem achieves the effect of allowing the user to view the service path more intuitively, thereby conveniently locating the location of the fault. Embodiment 2

Referring to FIG. 2, it is a flowchart of a method for displaying a service path in network fault maintenance according to Embodiment 2 of the present invention. The display method of the service path in the network fault maintenance may be applied to a terminal running a predetermined program, where the method for displaying the service path in the network fault maintenance may include: Step 201: Obtain object information of two objects, where the object is in the network A physical network element or a virtual network element that contains part of object information of a physical network element.

When the user wants to find the service path of two objects, the terminal may first acquire the object information of the two objects input by the user. The object is a physical network element in the network or a virtual network element that contains part of the object information of the physical network element. Specifically, the terminal acquires the object information of the two objects by using any one of the following three methods:

First, receiving object information input by the user in the preset text input area;

The terminal may provide a text input area to the user in advance, so that the user inputs the object information of the two objects that are to be searched for the service path in the text input area, where the object information includes the network element name, the network element interface name, and the network element interface IP address. Any one of the loopback address of the NE and the management IP address of the NE. For example, the user can input the IP address of the network element interface as the source end as "121.235.251.215" in the text input area 301, and the IP address of the network element interface as the sink end is "180.110.182.226", as shown in FIG. 3A.

Secondly, two virtual network elements including blank object information are provided in advance, and the user sets the object information of the two virtual network elements, where the object information includes the network element name, the network element interface name, the network element interface IP address, and Any of the loopback addresses of the NE.

The terminal may also provide two virtual network elements including blank object information in advance. When the user knows the object information of two objects, but cannot determine whether the object information is object information of a real physical network element, or the object cannot be determined. When the information of the physical network element is the object information, the object information may be set as the object information of the virtual network element. For example, the user may include the preset two blanks. The virtual network element 302 of the object information is dragged from the toolbar 303 to the path topology display area 304, as shown in FIG. 3B. The default names of the two virtual network elements 302 are all V, and then the user sets the object information of the two known objects to the object information of the two virtual network elements 302. After the setting is completed, the connection is selected in the toolbar 303, and the two virtual network elements 302 are connected by a connection to trigger the terminal to calculate the path information between the two virtual network elements 302.

Third, the receiving user selects a preset physical network element, and each preset physical network element stores corresponding object information, and the two preset physical network elements selected by the user are used as two objects. The user, when the user does not know the object information, but the two objects that need to be searched for the service path are the two physical NEs that are actually present, the corresponding physical network element can be directly selected from the physical network elements provided by the terminal. As two objects that need to find a service path, the terminal can pre-store object information of each physical network element without user input. For example, the terminal may provide 26 physical network elements including eight, B, C, and, and related topology relationships to the user in the physical topology display area 305, as shown in FIG. 3C. When the user needs to find the service path between the two physical network elements C and J, the "C" physical network element and the "J" physical network element can be directly dragged from the function panel area 305 to the path topology display area 304. . After the dragging is completed, the connection line is selected in the toolbar 303, and the "C" physical network element and the "J" physical network element are connected by a connection to trigger the terminal to find the path information between the two physical network elements. When the terminal searches for path information between the two physical network elements, it can use the pre-stored "C" physical network element and the object information of the "J" physical network element to search.

Step 202: Determine, according to the object information, a service type of the two objects, where the service type includes an asynchronous transmission mode service, a time division multiplexing service, or an Ethernet service.

When the terminal finds the service path between two objects, it can judge the service type of the two objects according to the object information of the two objects. Specifically, when the object information received by the terminal is the network element name or the management IP address of the network element, the terminal may query the corresponding physical physical network element according to the network element name or the management IP address of the network element, and further, may query Go to all the NE interface names, NE interface IP addresses, and/or loopback addresses of NEs on the actual physical NE, and then use the queried information to determine the service type of the two objects. Specifically:

When the object information that is received by the terminal and is queried according to the name of the network element or the management IP address of the network element is the name of the network element interface that is bound to PWE3 (Pseudo-Wire Emulation Edge to Edge). The service type of the object is determined as an ATM (Asynchronous Transfer Mode) service or a TDM (Time Division Multiplex) service. When the object information that is received by the terminal and is queried according to the name of the network element or the management IP address of the network element is the name of the network element interface that is not bound to the PWE3, the service type of the object is determined to be a service type that cannot be searched.

When the object information that is received by the terminal or that is queried by the network element name or the management IP address of the network element is the IP address of the network element interface or the loopback address of the network element, the service type of the object is determined to be Ethernet service.

Step 203: If it is determined that the service type of the two objects is an asynchronous transfer mode service or a time division multiplexing service, the service path between the two objects is searched according to the first manner.

Specifically, when the object information that is received by the terminal and is queried according to the network element name or the management IP address of the network element is the name of the network element interface bound to the PWE3, the service path between the two objects is searched according to the first manner. , can be achieved by the following steps:

The terminal can query the corresponding PW (Pseudo-Wire) device according to the object information of the object as the source end (the network element interface name bound to the PWE3).

Query the configuration of the corresponding pseudowire path and/or the pseudowire type according to the configuration information in the pseudowire device. You can query the configuration of the corresponding NE interface name and/or the pseudowire according to the configuration information on the queried PW device. Types of. The configuration may include a normal PW, a bypass PW (Chinese: bypass PW), and an active/standby PE. The pseudowire type may include a normal PW, a multi-segment PW, and a redundant PW.

Find the working path according to the configuration and / or pseudowire type;

You can find the working path based on the configuration and / or the pseudowire type. You can find the NE of the peer directly based on the configuration. For Bypass PW, active and standby PEs, multi-segment PWs, and redundant PWs, there are many or multiple paths, and the actual working path needs to be further determined. After determining a working path or a working path, the tunnel corresponding to the working path can be found asynchronously.

The traversed network elements and links are searched according to the working path, and the determined network elements and links are used as service paths.

According to the above working path, the traversed network element and the link can be searched, and the determined network element and link are used as the service path. For example, for a multi-segment PW, the network element that is the source end, the network element that is connected between each PW, and the network element that serves as the sink end can be determined according to the working path.

Step 204: If it is determined that the service type of the two objects is an Ethernet service, the service path between the two objects is searched according to the second manner.

Specifically, when the terminal receives the query according to the name of the network element or the management IP address of the network element When the object information of the two objects is the IP address of the network element interface or the loopback address of the network element, the service path between the two objects is searched according to the second method, which can be implemented by using the following steps:

First, the longest IP address is matched according to the object information and the object information of the preset physical network element; the terminal matches the IP address in the received object information with the object information of the preset physical network element for the longest IP address. After the longest IP address is matched, the actual physical network element closest to the IP address in the received object information can be found, so as to be the entry point when searching for the service path. For example, the process of matching the longest IP address may be: The object information of each preset physical network element stored in the terminal is not a specific IP address, but a variable length network prefix. For example, assume that the object information of two physical network elements is "202.168.XX, output port 1, and "202.168.16.X, output port 2" (X means arbitrary), if the IP of the received object information The address is 202.168.16.5. After the longest IP address is matched, the physical NE with the IP address "202.168.16.X" is used as the matching physical NE.

In this step, if the object information is input by the user through the text input area mode or the virtual network element mode, the two physical network elements can be matched. For example, if the user inputs two object information through the virtual network element mode, The physical network element and the "V" physical network element are matched to the "F" physical network element; if the object information is input by the user through the preset physical network element, the physical network element can be directly matched to the preset physical network element, for example, the user passes the preset physical network element. In the mode, the "C" physical network element and the "J" physical network element are input, and the "C" physical network element and the "J" physical network element can be directly matched.

Second, the corresponding forwarding table is queried according to the object information of the physical network element as the source end in the matched physical network element, and the forwarding table includes any one or a combination of the routing forwarding table, the MAC address forwarding table, and the label forwarding table. ;

After the matching physical network element, the terminal can use the object information of the physical network element as the source end to query the corresponding forwarding table on the corresponding network element. The forwarding table can be a routing forwarding table, a MAC address forwarding table, and a label forwarding table. Any combination of one or more. According to the forwarding information, the next station network element and the corresponding forwarding link forwarded when the service from the source end to the sink end is forwarded on the network element can be queried.

For example, when the terminal searches for the service path between the "C" physical network element and the "J" physical network element, the terminal can query the next station network element to be "F" physical network according to the forwarding table on the "C" physical network element. And continue to query the next network element as the "H" physical network element according to the forwarding table on the "F" physical network element, and so on, and gradually determine the network passing through the service path. Meta and link, as shown in Figure 3D.

Third, the service is gradually determined according to the forwarding information related to the physical network element as the source end in the forwarding table. The network element and link that are forwarded to the sink end, and the determined network element and link are used as the service path. By querying and analyzing the forwarding table of each network element one by one, the terminal can gradually determine the network elements and links that the service passes through when forwarding the service to the sink, and use the determined network element and link as the service path.

For example, when the terminal searches for the service path between the "C" physical network element and the "J" physical network element, the terminal can finally determine the forward traffic path between the "C" physical network element and the "J" physical network element. The network element has CFHDGVMJ, and the network element through which the reverse service path passes has JMZGDHFC.

Step 205: The icons of the two objects are always displayed, and each time a network element or link on the service path of the two objects is determined, the network element and the link are displayed in a predetermined manner between the two objects.

The terminal can always display two objects on the interface that need to query the service path, such as "C" physical network element and "J" physical network element, and then determine a network element or chain on the service path of the two objects each time. In the case of a road, the network element or link is displayed in a predetermined manner between the two objects. The predetermined manner may include: adding an icon between two objects to represent the network element; using a solid line to represent the link between the two objects; and/or, using a dotted line or a dynamic dotted line between the two objects to indicate an undetermined network Meta and link.

As shown in FIG. 3D, when searching for the service path between the "C" physical network element and the "J" physical network element, when the "F" physical network element is found, the icon "F" may be added to indicate the found". F" physical network element; at the same time, the solid link between the "C" physical network element and the "F" physical network element can be used to represent the discovered link; in addition, the "H" physical network element and the "J" physical network Undetermined network elements and links may also be represented by dashed lines or dynamic dashed lines.

Step 206: Find a complete service path of the corresponding service according to the service path between the two objects; display the network element and the link on the complete service path.

Since the two objects specified by the user are not necessarily the true source and sink of the corresponding service. Therefore, after finding the service path between the two objects specified by the user, the E2E path of the corresponding service, that is, the end-to-end path, may also be referred to as a complete service path. For example, the two objects specified by the user are the "C" physical network element and the "J" physical network element. After finding the service path between the "C" physical network element and the "J" physical network element, the terminal can continue to find this. The complete service path of the service corresponding to the service path, and the complete service path finally found, such as rd, is shown in Figure 3E. The process of continuing the search is similar to steps 202 through 204. The process of continuing to search can be triggered by the user double-clicking the service path between the "C" physical network element and the "J" physical network element.

Step 207: Display or process the operation on the service path according to the user.

After the terminal finds the service path or the complete service path between the two objects, the user can display or perform subsequent operations on the service path. Specifically: First, the performance parameter of the network element or link selected by the user is displayed, and the performance parameters include: at least one of an alarm signal, a bandwidth utilization rate, a CPU usage rate, a memory occupancy rate, a generation value, and a maximum transmission unit value.

The terminal may receive the user's selection of the network element or the link on the service path, and after receiving the corresponding selection signal, display performance parameters of the network element or link selected by the user, and the performance parameters may be pre-stored in the terminal. Internally, it can also be obtained by the terminal immediately querying the corresponding network element.
