Description

Technical Field

[0001] The present application relates to the field of network communications, and more specifically to a control method for a wavelength division transmission network, a control device for a wavelength division transmission network, a computer device for controlling a wavelength division transmission network, a non-transitory computer-readable storage medium, and a computer program product. Background Art

[0002] With the continuous development of the Internet and information technology, data centers generally include multiple computer rooms located in various places to meet production and use needs. To ensure the dominance of operation and maintenance, any two computer rooms are generally interconnected through primary and backup optical fibers and connected to primary and backup wavelength division equipment to build transmission channels in the computer room. The network devices inside the computer room are then interconnected with the primary and backup wavelength division equipment in turn to finally meet the data communication needs of the computer room. In actual applications, due to the large range of production business systems involved in the interconnection traffic between computer rooms, currently multiple computer rooms often require dozens of lines to realize the interconnection between the network equipment and wavelength division equipment in each computer room, and there is still a trend of continued expansion in the future.

[0003] With the rapid development of business and the increasing number of production systems, data centers have put forward higher requirements on the coverage of the available mechanism of production systems. In traditional operation and maintenance scenarios, when the optical fiber interconnecting between computer rooms fails, the wavelength division equipment can switch between the primary and backup optical fibers to meet the high availability requirements of the transmission channels between computer rooms. However, once the wavelength division equipment fails, it cannot switch traffic by itself, and it needs to rely on the network equipment connected to it to switch traffic to the backup wavelength division equipment to ensure the effectiveness of the high availability mechanism. The traffic switching of network devices needs to rely on routing configuration, but some static routes will continue to take effect if the interconnection ports are not interrupted, resulting in the network device being unable to switch traffic to the backup wavelength division equipment. This situation often requires manual intervention, such as manually closing the interconnection port between the network device and the wavelength division device to achieve traffic switching, but this manual intervention cannot guarantee the timeliness of the switching, and thus cannot meet the high availability requirements of the transmission channels between computer rooms, and it also requires a lot of manpower and material resources.

[0031] Hereinafter, various exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings.

[0032] Figure 1 A schematic diagram of a typical wavelength division transmission network is shown.

[0033] like Figure 1 As shown in , the wavelength division transmission network 1 includes network equipment 10, network equipment 20, network equipment 30, wavelength division equipment 40A, 41A, 42A and wavelength division equipment 40B, 41B, 42B, wherein the network equipment 10, network equipment 20 and network equipment 30 are respectively arranged in the machine room 1, the machine room 2 and the machine room 3 and each includes a primary and a standby network equipment. Optionally, the wavelength division equipment 40A, 41A, 42A can be respectively arranged in the machine room 1, the machine room 2 and the machine room 3 and form a wavelength division A plane, and the wavelength division equipment 40B, 41B, 42B can be respectively arranged in the machine room 1, the machine room 2 and the machine room 3 and form a wavelength division B plane.

[0034] As an example, Figure 1As shown in , a network link can be established between the network device 10 and the network device 20 via the wavelength division A plane, and a network link can be established between the network device 10 and the network device 30 via the wavelength division B plane.

[0037] Figure 2 FIG. 1 is a flow chart showing a method for controlling a wavelength division transmission network according to one or more embodiments of the present application. Figure 2 The control method shown in Figure 1 The wavelength division transmission network shown in FIG. 1 is taken as an example to describe a control method of a wavelength division transmission network according to one or more embodiments of the present application.

[0038] like Figure 2 As shown in FIG. 2 , in step S201 , a detection communication path is established between part or all of the multiple network devices via one or more wavelength division devices among the multiple wavelength division devices.

[0039] Optionally, in step S201, a virtual interface address and routing information based on the virtual interface address may be configured on some or all of the network devices among the multiple network devices, and a detection communication path through one or more wavelength division devices among the multiple wavelength division devices may be established between some or all of the network devices among the multiple network devices according to the configured virtual interface address and the routing information based on the virtual interface address. It should be noted that the routing information based on the virtual interface address may be used to indicate a deterministic detection communication path, such as a uniquely determined detection communication path, between some or all of the network devices among the multiple network devices through one or more wavelength division devices among the multiple wavelength division devices. Exemplarily, a Loopback virtual address and an end-to-end detailed route based on the Loopback virtual address may be configured on two network devices, so that the communication path of the mutual access traffic between the two network devices based on the Loopback virtual address is implemented through one or more wavelength division devices interconnected with the two network devices.

[0040] In one embodiment, one or more network links among all network links in the wavelength division transmission network may be selected as the detection communication path. Figure 1 The wavelength division transmission network 1 shown in the figure can configure a virtual interface address and routing information based on the virtual interface address on the right network device of the network device 10 and the right network device of the network device 30, and establish a detection communication path between the right network device of the network device 10 and the right network device of the network device 30 via the right wavelength division device of the wavelength division device 40B and the right wavelength division device of the wavelength division device 42B according to the configured virtual interface address and the routing information based on the virtual interface address, that is, Figure 1 The network link between the right network device of the network device 10 and the right wavelength division device of the wavelength division device 40B and the network link between the right network device of the network device 30 and the right wavelength division device of the wavelength division device 42B are used as the detection communication path. As an example, refer to Figure 1 The wavelength division transmission network 1 shown in the figure can configure a virtual interface address and routing information based on the virtual interface address on the left network device of the network device 10 and the left network device of the network device 20, and establish a detection communication path between the left network device of the network device 10 and the left network device of the network device 20 via the left wavelength division device of the wavelength division device 40A and the left wavelength division device of the wavelength division device 41A according to the configured virtual interface address and the routing information based on the virtual interface address, that is, Figure 1 The network link connected between the left network device of network device 10 and the left wavelength division device of wavelength division device 40A and the network link connected between the left network device of network device 20 and the left wavelength division device of wavelength division device 41A are used as detection communication paths.

[0041] In step S203, an abnormality detection is performed on the probe communication path to generate an abnormality detection result associated with one or more wavelength division devices.

[0042] Optionally, in step S203, an abnormality detection associated with network connectivity may be performed on the detection communication path, and an abnormality detection result associated with the one or more wavelength division devices is generated in response to determining that an abnormality occurs in one or more wavelength division devices or an abnormality occurs in the wavelength division plane including the one or more wavelength division devices. In performing the abnormality detection associated with network connectivity, a request message may be transmitted via the detection communication path, and a response message in response to the request message may be detected to perform the abnormality detection associated with network connectivity on the detection communication path.

[0043] Optionally, Ping test, Traceroute / Tracepath test, Telnet / SSH test, Pathping test, etc. may be used to perform abnormality detection associated with network connectivity. In one embodiment, Ping packets may be transmitted via the established detection communication path, and the transmission status of the Ping packets may be detected to perform abnormality detection associated with network connectivity on the detection communication path. For example, when it is detected that Ping packets are lost or Ping packets are not connected in both directions on a single or part of the point-to-point channels, it may be determined that an abnormality has occurred in one or more wavelength division devices via the detection communication path; when it is detected that Ping packets are lost or Ping packets are not connected in both directions on all point-to-point channels, it may be determined that an abnormality has occurred in the wavelength division plane via the detection communication path.

[0044] In step S205, device information of one or more network devices among some or all network devices is determined in a pre-built device database based on the detection communication path identification information corresponding to the abnormality detection result, so as to perform isolation control operations on one or more network devices based on the determined device information.

[0045] In one embodiment, the pre-built device database may store the communication path identification information in the wavelength division transmission network and the network device name, network device port, port network address, and service system corresponding to the network device associated with the communication path identification information. Figure 3 As shown, further description is given.

[0046] In one embodiment, the communication path identification information can be represented by a combination of letters and numbers, where the letters and numbers in the combination of letters and numbers are respectively determined by the wavelength division transmission plane, the wavelength division device, the transmission bandwidth, the board information of the wavelength division device, and the port information of the wavelength division device. The communication path identification information will refer to the following Figure 4As shown, further description is given.

[0047] Optionally, in step S205, communication path identification information matching the detected communication path identification information can be determined in a pre-built device database, and one or more of the associated network device name, network device port, and port network address can be determined based on the matched communication path identification information as device information of one or more network devices in part or all of the network devices. Then, the port of the corresponding network device can be closed based on the device information of the network device, so that one or more wavelength division devices associated with the abnormal detection result can be isolated based on the routing mechanism of the corresponding network device.

[0048] According to one or more embodiments of the present application, the control method of the wavelength division transmission network can realize the isolation control operation of the network device by detecting abnormalities in the detection communication path, so as to realize the automatic and rapid switching of the interconnection line between the network device and the wavelength division device, improve the operation and maintenance efficiency and the availability of the wavelength division transmission network, thereby realizing more efficient business operations, and saving the human and material resources consumed by manual intervention. In addition, according to one or more embodiments of the present application, the control method of the wavelength division transmission network can realize cross-level emergency disposal of the physical layer devices in the OSI seven-layer model by implementing isolation control operations on the network layer devices in the OSI seven-layer model.

[0049] Figure 3 A schematic diagram showing a typical pre-built device database.

[0050] like Figure 3 As shown in, the pre-built device database 300 stores the communication path identification information in the wavelength division transmission network and the device information of the network device associated with the communication path identification information, the device information of the network device may include the network device name, the network device port, the port network address and the service system corresponding to the network device, wherein the communication path identification information may be represented by a combination of letters and numbers, and the letters and numbers in the combination of letters and numbers may be respectively determined by the wavelength division transmission plane, the wavelength division device, the transmission bandwidth, the board information of the wavelength division device, and the port information of the wavelength division device. The following will be combined with Figure 4 Further description. It should be noted that Figure 3 The schematic diagram of a typical pre-built device database is only shown as an example, without departing from the spirit and scope of the present application. Figure 3 The pre-built device database shown in can be modified or replaced, for example, using other forms other than tabular form to store communication path identification information and device information of network devices associated with the communication path identification information, or containing a larger number of communication path identification information and device information of network devices associated with the communication path identification information.

[0051] By pre-building a device database, it is possible to establish an association relationship between the communication path identification information of the interconnection line between the network device and the wavelength division device and the device information of the network device, so that other associated information can be obtained based on the communication path identification information and any one of the device information of the network device, that is, for example, through the communication path identification information A13101201 shown in the second row of the pre-built device database 300, the network device name BC-P-709-J3-28U-NSW01, the network device port 40GE1 / 0 / 1:2, the port network address abcd and the business system of the intranet business access switch interconnected with the network device are obtained, which helps to accurately and quickly perform isolation control operations on one or more network devices, thereby improving operation and maintenance efficiency.

[0052] Figure 4 A schematic diagram showing typical communication path identification information.

[0053] like Figure 4 As shown in FIG. 4 , the communication path identification information 400 is represented by a combination of letters and numbers, for example, Figure 4 The 9-digit combination of letters and numbers shown in the figure indicates that the first letter indicates the wavelength division plane where the communication path is located, the second and third digits indicate the numbers of the two wavelength division devices interconnected by the communication path, the fourth and fifth digits indicate the bandwidth of the communication path, the sixth and seventh digits indicate the board number of the wavelength division device corresponding to the communication path, and the eighth and ninth digits indicate the port number of the wavelength division device corresponding to the communication path. By identifying the communication path in the above manner, not only the communication path is unique, but also the bandwidth and deployment location of the communication path can be accurately reflected.

[0054] As an example, refer to Figure 4 As shown, the communication path identification information A25100402 can be used to indicate that the wavelength division plane where the communication path is located is the wavelength division A plane, the two wavelength division devices interconnected by the communication path are wavelength division devices 02 and wavelength division devices 05, the bandwidth of the communication path is 10G, the board number of the wavelength division device corresponding to the communication path is 4, and the port number of the wavelength division device corresponding to the communication path is 2. It should be noted that Figure 4 This is only a schematic diagram showing a typical communication path identification information as an example, and without departing from the spirit and scope of the present application, Figure 4 The communication path identification information shown in can be modified or replaced, for example, by using a combination of letters and numbers with more or fewer digits.

[0055] Figure 5A schematic block diagram of a control device for a wavelength division transmission network according to one or more embodiments of the present application is shown.

[0056] like Figure 5 As shown in FIG. 5 , the control device 500 of the wavelength division transmission network includes a query device 510 , a detection device 520 and an emergency device 530 .

[0057] The query device 510 is configured to store a pre-built device database, wherein the pre-built device database stores communication path identification information in the wavelength division transmission network and device information of network devices associated with the communication path identification information, for example, referring to the above Figure 3 and Figure 4 as described.

[0058] The detection device 520 is configured to perform anomaly detection on the detection communication path to generate anomaly detection results associated with one or more wavelength division devices, wherein the detection communication path is established between some or all of the multiple network devices via one or more wavelength division devices among the multiple wavelength division devices.

[0059] The emergency device 530 is configured to determine device information of one or more network devices among part or all of the network devices based on the detection communication path identification information corresponding to the abnormality detection result, so as to perform an isolation control operation on the one or more network devices based on the device information.

[0060] Optionally, the detection device 520 may include an abnormality detection unit and a message receiving unit ( Figure 5 510), wherein the abnormality detection unit is configured to perform abnormality detection associated with network connectivity on the detection communication path, and generates abnormality detection results associated with one or more wavelength division devices in response to determining that an abnormality occurs in one or more wavelength division devices or an abnormality occurs in the wavelength division plane including one or more wavelength division devices, and the message receiving unit is configured to receive the abnormality detection result and determine the detection communication path identification information corresponding to the abnormality detection result via the pre-built device database stored in the query device 510, and send the determined detection communication path identification information to the emergency device 530. In one embodiment, the abnormality detection unit can be set Figure 1 The various computer rooms shown in the figure are, for example, located in Figure 1 The computer room 1, computer room 2 and computer room 3 shown in the figure transmit a request message via a detection communication path, and detect a response message in response to the request message to perform an abnormality detection associated with network connectivity on the detection communication path. In one embodiment, the message receiving unit can be set Figure 1 The various computer rooms shown in the figure are, for example, located in Figure 1In one embodiment, a single message receiving unit may be provided to receive the abnormality detection results from the abnormality detection unit.

[0061] In one embodiment, the anomaly detection unit may use Ping test, Traceroute / Tracepath test, Telnet / SSH test, Pathping test, etc. to perform anomaly detection associated with network connectivity. In one embodiment, the anomaly detection unit may transmit Ping packets via the established detection communication path, and detect the transmission status of the Ping packets to perform anomaly detection associated with network connectivity on the detection communication path. For example, when it is detected that Ping packets are lost or Ping packets are not connected in both directions of a single or part of the point-to-point channels, the anomaly detection unit may determine that an anomaly occurs in one or more wavelength division devices via the detection communication path; when it is detected that Ping packets are lost or Ping packets are not connected in both directions of all point-to-point channels, the anomaly detection unit may determine that an anomaly occurs in the wavelength division plane via the detection communication path. Then, the anomaly detection unit may generate an anomaly detection result associated with one or more wavelength division devices via the detection communication path, and send the anomaly detection result to the message receiving unit.

[0062] As an example, the anomaly detection unit may periodically perform anomaly detection associated with network connectivity on the detected communication path, and periodically send the anomaly detection result to the message receiving unit. As an example, to ensure that the anomaly detection result is not affected by the transmission failure across the computer room, the anomaly detection unit may be distributedly connected to the edge network device of each computer room and perform anomaly detection. Exemplarily, the anomaly detection unit may perform periodic network connectivity detection by means of Ping with source address, determine whether the traffic reaches the network device in the opposite computer room through the designated detected wavelength division device, and realize unidirectional detection of the interconnection line between the network device and the wavelength division device. Exemplarily, when multiple computer rooms are provided in the wavelength division transmission network, bidirectional detection of the interconnection line between the network device and the wavelength division device, as well as overall detection of the plane status of the wavelength division device may be realized.

[0063] Optionally, the emergency device 530 can be configured to determine the communication path identification information that matches the detected communication path identification information via the pre-built device database stored in the query device 510, determine the associated network device name, network device port, port network address or one or more of the device information of one or more network devices in part or all of the network devices based on the matched communication path identification information, and close the ports of one or more network devices based on the device information, so as to isolate one or more wavelength division devices associated with the abnormal detection result based on the routing mechanism of one or more network devices. The query device according to one or more embodiments of the present application can accurately feedback various information stored in the pre-built device database, and is more suitable for the operation and maintenance scenarios within the data center.

[0064] Figure 6 A schematic block diagram of a detection device according to an embodiment of the present application is shown.

[0065] like Figure 6 As shown in , the detection device 600 includes an abnormality detection unit 610 and a message receiving unit 620.

In one embodiment, the anomaly detection unit 610 can transmit Ping packets via the established detection communication path, and detect the transmission status of Ping packets to perform anomaly detection associated with network connectivity on the detection communication path. For example, when it is detected that Ping packets are lost or Ping packets are not connected in both directions of a single or part of the point-to-point channels, the anomaly detection unit 610 can determine that an anomaly occurs in one or more wavelength division devices via the detection communication path; when it is detected that Ping packets are lost or Ping packets are not connected in both directions of all point-to-point channels, the anomaly detection unit 610 can determine that an anomaly occurs in the wavelength division plane via the detection communication path. Then, the anomaly detection unit 610 can generate an anomaly detection result associated with one or more wavelength division devices via the detection communication path, and send the anomaly detection result to the message receiving unit 610.

To ensure that the anomaly detection result is not affected by the cross-machine room transmission failure, the anomaly detection unit 610 may be distributedly accessed to the edge network device of each machine room and perform anomaly detection, such as Figure 6 As shown in . Exemplarily, the anomaly detection unit 610 can perform periodic network connectivity detection by means of source address Ping to determine whether the traffic reaches the network device in the opposite computer room through the designated detected wavelength division device, thereby realizing one-way detection of the interconnection line between the network device and the wavelength division device. Exemplarily, when multiple computer rooms are provided in the wavelength division transmission network, bidirectional detection of the interconnection line between the network device and the wavelength division device, as well as overall detection of the plane status of the wavelength division device can be realized.
