Optical Transport Network (OTN) is a type of transmission network, which refers to a transmission network that realizes the transmission, multiplexing, routing, and monitoring of service signals in the optical domain, and ensures its performance indicators and survivability. OTN uses Wavelength Division Multiplexing (WDM) technology as the basis to ensure super large transmission capacity and also joins the strong operation, maintenance and management capabilities of Synchronous Digital Hierarchy (SDH). OTN has inherited many advantages of SDH and WDM technologies, and has become the mainstream technology of optical transport network in the industry. The optical transport network can provide flexible architecture and differentiated services for operators in the era of IP (Internet Protocol, International Internet Protocol) and optical convergence while making full use of transmission infrastructure resources.

At the same time, with the general development of cloud computing, the demand for multi-domain interconnection and cloud-network integration has promoted the integration of cloud pools and optical networks. Users can rent OTN circuits with low latency, high reliability, and flexible bandwidth to access cloud pools, which is easier to implement Convergence of cloud pool and optical network. With the development of emerging services such as 5G, cloud services, and the Internet of Things, OTN technology is also developing rapidly.

With the rapid development of 5G technology and the great enrichment of upper-layer business applications, business applications have further increased their emphasis on delay performance indicators. Latency-sensitive services for public users, such as: video, cloud games, etc., while government affairs, medical care, Related users such as education and industrial Internet have also put forward higher requirements for latency performance indicators.

In the prior art, after a user rents an optical transport network of a telecom operator, he cannot directly view and understand service performance data such as topology structure, delay information, bandwidth utilization rate, and traffic index of the leased optical transport network circuit. When a fault occurs in an optical transport network circuit, the fault cannot be resolved in time, resulting in low fault handling efficiency.

The present application provides a method for obtaining circuit information of an optical transport network. When a user needs to query circuit information of an optical transport network, a service query request can be sent to a customer network management platform, and the customer network management platform forwards the service query request to a cloud-network coordinator. The cloud-network coordinator initiates a circuit information query request to the OTN network controller, and the OTN network controller can query the UUID of the tunnel according to the UUID of the OTN circuit carried in the circuit information query request.

Send the OTN circuit information to the customer's network management platform, and the customer's network management platform can display the OTN circuit information to the user with an intuitive graphical interface, which is clear and clear. The method of the present application can check the circuit topology information and service performance data of the optical transport network circuit, and when the optical transport network circuit fails, the fault cause can be quickly located according to the optical transport network circuit information, thereby improving the fault handling efficiency.

The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below in conjunction with the accompanying drawings.

FIG. 1 is a flowchart 1 of a method for obtaining circuit information of an optical transport network provided by an embodiment of the present application. The method in this embodiment can be executed by the cloud-network coordinator, and can be realized by hardware, software, or a combination of hardware and software. As shown in Figure 1, the method of this application is specifically as follows:

S101: Receive a service query request sent by a customer network management platform, where the service query request carries a service name of an OTN circuit.

The customer network management platform can provide an application program (Application), a small program or a PC (Personal Computer, personal computer) client as a service contact, receive a service query request input by a user, and send the service query request to the cloud network system device. Specifically, the client network management platform may be a lightweight client network management platform, which is less complicated to develop and convenient.

S102: Based on the service query request, send a circuit information query request to the OTN network controller, where the circuit information query request carries the universal unique identification code of the optical transport network circuit, and the universal unique identification code corresponds to the service name.

Since the OTN network controller cannot recognize the service name, before sending the circuit information query request to the OTN network controller, it is necessary to convert the service name into interface message information that the OTN network controller can recognize. In one implementation scenario, the business name may be converted into a universally unique identifier (Universally Unique Identifier, UUID) corresponding to the business name.

S103: Receive the universal unique identification code of the tunnel corresponding to the OTN circuit returned by the OTN network controller based on the circuit information query request.

Different OTN circuits correspond to different tunnels. After receiving the circuit information query request, the OTN network controller can query the UUID of the tunnel corresponding to the OTN circuit according to the UUID of the OTN circuit, and return the UUID of the tunnel to Cloud network synergy.

S104: Send a circuit tunnel information query request to the OTN network controller, where the circuit tunnel information query request carries a universal unique identification code of the tunnel.

The circuit tunnel information query request is used to query circuit tunnel information. The network controller of the optical transport network can query the circuit tunnel information of the tunnel according to the universal unique identification code of the tunnel in the circuit tunnel information query request, and return the circuit tunnel information to the cloud network coordinator.

The circuit tunnel information may include one or more of the following information: path role information, path running status information, network element ID information, and path end-to-end one-way delay information.

S105: Receive circuit tunnel information sent by the OTN network controller.

In one implementation scenario, optical transport network circuits can be divided into point-to-point networking circuits and point-to-point cloud circuits. Wherein, in the point-to-point networking circuit, both the source node and the sink node are CPE (Customer Premise Equipment, Customer Premise Equipment) equipment, and there are two paths from the source node to the sink node, which are the working path and the protection path. In the point-to-point cloud circuit, the source node is a CPE device, and the sink node is an optical transport network device. There are also two paths from the source node to the sink node, which are the working path and the protection path. It should be noted that the source node and the sink node are located within the range of the OTN network controlled by the same OTN network controller.

Therefore, the path role information contained in the circuit tunnel information is used to indicate the role of the current path, that is, the working path and the protection path. The path health status indicates whether the path is healthy. The path end-to-end one-way delay information is the time required for the signal to be transmitted from the source node to the sink node.

S106: Generate circuit topology information according to circuit tunnel information and OTN network information, and generate OTN circuit information according to circuit topology information and service performance data.

The OTN network information and service performance data are stored in the cloud-network synergist database. In one implementation scenario, before receiving the service query request sent by the customer network management platform, the network information of the optical transport network can be periodically obtained from the network controller of the optical transport network. The network information of the optical transport network includes network element information and link unidirectional time Extended information, network element information includes network element identification number ID information, network element name and the mapping relationship between network element ID information and network element name; save the optical transport network network information to the cloud network synergist database.

In addition to the OTN network information, the cloud-network coordinator database also stores service performance data. Before receiving the service query request sent by the customer network platform, it can also periodically obtain the service performance data of the optical transport network network from the network controller of the optical transport network, analyze the service performance data, and save the analyzed service performance data to the cloud Network Synergist Database.

The service performance data may include one or more of the following: bandwidth utilization rate, traffic index, packet loss rate index, and jitter index of the optical transport network circuit.

Circuit topology information is the information describing the topology structure and circuit delay of optical transport network circuits, which can include: network element name, path hop-by-hop link bidirectional delay information, path end-to-end bidirectional delay information, path role information and path Operating status information, etc.

Before generating the OTN circuit information based on the circuit topology information and service data, the service performance data of the OTN circuit can be queried in the cloud network synergist database according to the universal unique identification code of the OTN circuit.

S107: Send the OTN circuit information to the client network management platform.

The customer network management platform can display the circuit topology information and service performance data to the user in an intuitive graphical interface according to the received optical transport network circuit information, which is clear and clear, which is helpful for users to quickly understand the relevant information of the optical transport network circuit, thereby improving efficiency.

In one implementation scenario, after the OTN circuit information is sent to the customer network management platform, the OTN network controller subscribes to the alarm message of the change of the path role information of the OTN circuit and the change of the OTN circuit route. When the OTN network controller detects that the path role information of the OTN circuit or the route of the OTN circuit changes, it sends an alarm message to the cloud network coordinator. After the cloud-network synergist receives the alarm message, it needs to wait for a certain period of time until the state of the optical transport network circuit is stable, such as 30s, and then sends the alarm message to the customer network management platform, and the customer network management platform can notify the user, thereby improving the reliability of the optical transport network circuit. safety.

The embodiment of the present application provides a method for obtaining information of an optical transport network circuit, which receives a service query request sent by a customer network management platform, and the service query request carries the service name of the optical transport network circuit. The business name of the network circuit of the optical transport network is converted into a universal unique identification code that can be recognized by the network controller of the optical transport network. Based on the service query request, a circuit information query request is sent to the OTN network controller, and the circuit information request carries the universal unique identification code of the OTN circuit. Receive the universal unique identification code of the tunnel corresponding to the optical transport network circuit returned by the optical transport network network controller based on the circuit information query request, and send the circuit tunnel information query request to the optical transport network network controller, and the circuit tunnel information query request carries the tunnel Universal Unique Identifier for . Receive the circuit tunnel information sent by the OTN network controller, generate circuit topology information according to the circuit tunnel information and OTN network information, and generate OTN circuit information according to the circuit topology information and service performance data. Send the OTN circuit information to the customer network management platform, and the customer network management platform displays the OTN circuit information to the user with an intuitive graphical interface. The method provided in this application generates circuit topology information based on circuit tunnel information and OTN network information, and generates OTN circuit information based on circuit topology information and service performance data. The optical transport network circuit information can describe the topology structure, delay information and service performance of the optical transport network circuit. When a fault occurs in an optical transport network circuit, the cause of the fault can be quickly located according to the information of the optical transport network circuit, thereby improving the fault handling efficiency.

On the basis of the foregoing embodiments, an embodiment is provided below to describe in detail the process of generating circuit topology information according to circuit tunnel information and OTN network information.

FIG. 2 is a flow chart of a method for generating circuit topology information provided by an embodiment of the present application. The subject of execution of the method of this application may be a cloud-network coordinator, as shown in Figure 2, this method may include:

S201: Determine a network element name corresponding to the network element ID information according to the network element ID information and the optical transport network network information.

Because the circuit tunnel information includes path role information, path running status information, network element ID information, and path end-to-end one-way delay information. Wherein, the path role information includes the working path and the protection path, so the path running state information may also include the working path running state information and the protection path running state information. Similarly, the network element ID information includes the network element ID information of the working path and the network element ID information of the protection path.

The OTN network information stored in the cloud-network coordinator database includes a mapping relationship between network element ID information and network element names. In one implementation scenario, according to the network element ID information and the mapping relationship between the network element ID information and the network element name in the network information of the optical transport network, query the network element name corresponding to the network element ID information in the cloud-network synergy database , so as to determine the network element name of the working trail and the network element name of the protection trail.

S202: Determine the bidirectional delay information of the path hop-by-hop link according to the optical transport network network information.

The OTN network information stored in the cloud-network synergist database includes link one-way delay information and network element information, wherein the network element information may include network element ID information and network element port ID information. In one implementation scenario, the link one-way delay information can be queried in the database of the cloud-network coordinator according to the universal unique identification code of the optical transport network circuit. The two-way delay information of the path hop-by-hop link is determined according to the one-way delay information of the link. Two adjacent network elements can be used as a hop, and the unique link between the two network elements can be determined through the ID information of the two adjacent network elements and the port ID information of the network elements.

Its time delay is x. The link between port b of network element B and port a of network element A is called />

The time delay is y, and the two-way time delay of the link between network element A and network element B is x+y. Wherein, x and y are link one-way delay information included in the optical transport network network information.

S203: Determine the end-to-end two-way delay information of the path according to the end-to-end one-way delay information of the path and the two-way delay information of the hop-by-hop link of the path.

The path end-to-end two-way delay information may include the end-to-end two-way delay information of the working path and the end-to-end two-way delay information of the protection path. There are many ways to determine the end-to-end two-way delay information of the path according to the end-to-end one-way delay information of the path.

In one implementation scenario, since the end-to-end one-way delay information of the path is the end-to-end one-way delay information of the working path, twice the end-to-end one-way delay of the working path can be used as the end-to-end one-way delay information of the working path Two-way delay, that is, to obtain the end-to-end two-way delay information of the working path.

The end-to-end one-way delay information of the protection path can be determined based on the two-way delay information of the hop-by-hop link of the path passed by the protection path. In one implementation scenario, the sum of the end-to-end two-way delays of the paths passed by the protection path is used as the end-to-end two-way delay of the protection path to obtain the end-to-end two-way delay information of the protection path.

S204: Generate circuit topology information according to the network element name, path hop-by-hop link bidirectional delay information, path end-to-end bidirectional delay information, path role information, and path operating status information.

The circuit topology information can describe the topology structure and circuit delay information of the circuit, among which the network element name, path role information and path operation status information can describe the topology structure of the circuit, the path hop-by-hop link bidirectional delay information and the path end-to-end bidirectional The delay information may describe circuit delay information.

The bidirectional delay information of the path hop-by-hop link is determined according to the optical transport network network information. The path end-to-end two-way delay information is determined according to the path end-to-end one-way delay information and the path hop-by-hop link two-way delay information. The circuit topology information is generated according to the network element name, path hop-by-hop link bidirectional delay information, path end-to-end bidirectional delay information, path role information and path operation status information.

On the basis of the above-mentioned embodiments, an embodiment is provided below to describe the process of obtaining the circuit information of the OTN at the side of the OTN network controller.

FIG. 3 is a second flowchart of a method for obtaining circuit information of an optical transport network provided by an embodiment of the present application. The subject of execution of the method may be an OTN network controller, and may be realized by hardware, software, or a combination of hardware and software. As shown in Figure 3, the method of the present application may include:

S301: Receive a circuit information query request sent by the cloud-network coordinator, where the circuit information query request carries a universal unique identification code of the OTN circuit.

The circuit tunnel information may include path role information, path running status information, network element ID information, and path end-to-end one-way delay information.

Since a working path and a protection path are included between the source node and the sink node in the OTN circuit, the path role information can indicate the role of the path. The path running status indicates whether the working path and the protection path are running normally. The path end-to-end one-way delay information is the time required for the signal to be transmitted from the source node to the sink node, and may be the end-to-end one-way delay information of the working path.

S304: Query the information of the circuit tunnel according to the UUID of the tunnel, and send the information of the circuit tunnel to the cloud-network coordinator.

In one implementation scenario, after the circuit tunnel information is sent to the cloud-network coordinator, it can monitor whether the path role information of the OTN circuit and the OTN circuit route change. If the path role information of the optical transport network circuit or the route of the optical transport network circuit changes, an alarm message is sent to the cloud network coordinator. For example, if the path role information of the optical transport network circuit changes, for example, the working path of the optical transport network circuit fails, the protection path will be used as the working path at this time, and the alarm message will be sent to the cloud-network synergist, which improves the optical transport network.

In one implementation scenario, the OTN network information includes network element information and link one-way delay information, and the network element information includes network element ID information, network element name, and a mapping relationship between the network element ID information and the network element name. For example, the cycle for the cloud-network coordinator to periodically obtain the OTN network information from the OTN network controller may be one day, and may be at a time when there are fewer services every day, such as 6:00 am.

The service performance data may include one or more of the following: bandwidth utilization rate, traffic index, packet loss rate index, and jitter index of the optical transport network circuit. For example, the cycle for the cloud-network coordinator to periodically obtain service performance data from the OTN network controller may be 15 minutes.

After the cloud-network coordinator periodically obtains the OTN network information and service performance data from the OTN network controller, it stores the OTN network information and service performance data in the cloud-network coordinator database.

In an implementation scenario, if the cloud-network coordinator cannot query the network element information through the OTN network controller, the cloud-network coordinator can also query the resource management system for the network element information.

S402: The customer network management platform receives the user's service query request and forwards it to the cloud-network coordinator, where the service query request carries the service name of the OTN circuit.

The customer network management platform can be a lightweight customer network management platform, such as an application program, a small program, or a PC client, which is convenient and fast.

Users can actively query the information of optical transport network circuits. In one implementation scenario, when a user needs to inquire about OTN circuit information, he can enter the service name of the OTN circuit on the customer network management platform and send a service query request to obtain the OTN circuit information.

S403: The cloud-network coordinator sends a circuit information query request to the OTN network controller, and the circuit information query request carries a universal unique identification code corresponding to the service name of the OTN circuit.

Before the cloud-network coordinator sends a circuit information query request to the OTN network controller, it needs to convert the service name of the OTN circuit carried in the service query request into a universal unique identification code for the OTN circuit, which is used in the OTN network Controller identification.

S404: The OTN network controller queries the UUID of the tunnel corresponding to the OTN circuit according to the UUID of the OTN circuit, and returns the UUID of the tunnel to the cloud-network coordinator.

Different OTN circuits correspond to different tunnels, and the UUID of the OTN circuit can determine the corresponding OTN circuit, so the UUID of the OTN circuit can be used to determine the tunnel corresponding to the OTN circuit . The universal unique identifier of the tunnel can be used as the identification information of the tunnel.

S405: The cloud-network coordinator sends a circuit tunnel information query request to the OTN network controller, and the circuit tunnel information query request carries a universal unique identification code of the tunnel.

The circuit tunnel information query request is used to query circuit tunnel information, which may include one or more of the following information: path role information, path operation status information, network element ID information, and path end-to-end one-way delay information.

S406: The OTN network controller queries circuit tunnel information according to the tunnel's UUID, and sends the circuit tunnel information to the cloud-network coordinator.

Since the optical transport network circuit includes a working path and a protection path, the path role information can indicate that the current path is a working path or a protection path, so the path running state information includes the running state information of the working path and the running state information of the protection path. The network element ID information includes the network element ID information of the working path and the network element ID information of the protection path. The path end-to-end one-way delay information is the end-to-end one-way delay information of the working path.

In one implementation scenario, the circuit tunnel information is in JSON (JavaScript Object Notation, JS Object Notation) or XML (Extensible Markup Language, Extensible Markup Language) format, so after receiving the circuit tunnel information, the cloud-network coordinator needs to The tunnel information is analyzed and processed.

S407: The cloud-network synergist generates circuit topology information according to the circuit tunnel information and OTN network information, generates OTN circuit information according to the circuit topology information and service performance data, and sends the OTN circuit information to the client network management platform.

The cloud-network coordinator database includes optical transport network network information and service performance data. The OTN network information and service performance data are obtained periodically from the OTN network controller before the cloud network coordinator receives the service query request.

The service performance data may include one or more of the following: bandwidth utilization rate, traffic index, packet loss rate index, and jitter index of the optical transport network circuit.

Wherein, the bandwidth utilization rate of the optical transport network circuit may take the maximum value of the peak utilization rate of the uplink or downlink bandwidth.

The traffic index can display the upstream traffic and downstream traffic of the optical transport network circuit separately, including the traffic index and historical traffic changes in the latest collection period. The historical traffic changes can be traffic changes within a week. According to the traffic index, the current and recent traffic conditions of the optical transport network circuit can be grasped in time, so as to determine the time for expanding the capacity of the optical transport network circuit, and improve the accuracy and timeliness of capacity expansion.

The packet loss rate index may take the maximum value of the uplink packet loss rate or the downlink packet loss rate of the OTN circuit. The jitter index can take the maximum value of the uplink jitter or downlink jitter of the OTN circuit.

The process of the cloud-network coordinator generating circuit topology information according to the circuit tunnel information and the OTN network information has been described in detail in the foregoing embodiments, and will not be repeated here.

S408: The customer network management platform displays the OTN circuit information with an intuitive graphical interface.

The customer network management platform displays the optical transmission network circuit information with an intuitive graphical interface, which is clear and intuitive. For example, the circuit topology information in the optical transport network circuit information can be generated into a circuit topology diagram and displayed to the user, as shown in FIG. 5 . Fig. 5 is a circuit topology diagram of a point-to-point cloud circuit.

In one implementation scenario, the path operation status information included in the optical transport network circuit information is two operation states of up and down, wherein up indicates that the path is in a normal operation state, and down indicates that the path is in an interrupted state. The customer network management platform can use different colors to distinguish the path running status. For example, display healthy paths in green and broken paths in red.

Since the optical transport network circuit can be connected to the cloud pool, users can integrate the cloud pool and optical network according to the optical transport network circuit information displayed on the customer network management platform, which is conducive to improving the efficiency of cloud pool and optical network integration.

S409: The cloud-network coordinator subscribes to the OTN network controller for the alarm message of the change of the path role of the OTN circuit and the change of the OTN circuit route.

In an implementation scenario, the cloud network coordinator may send a subscription message to the OTN network controller through an application programming interface (Application Programming Interface, API).

Taking the path role change of an OTN circuit as an example, since the path role information of an OTN circuit includes a working path and a protection path, switching between the working path and the protection path can be performed. When the working path fails, the protection path is switched to the working path, that is, the path role of the initial protection path at this time is the working path.

S410: The OTN network controller monitors whether the path role information of the OTN circuit and the route of the OTN circuit change.

In one implementation scenario, when the network controller of the OTN monitors that the path role information of the OTN circuit or the route of the OTN circuit changes, it sends an alarm message to the cloud network coordinator. The cloud network synergist waits for a certain period of time until the OTN circuit is stable, and then sends the alarm message to the customer network management platform.

In one implementation scenario, if the customer network management platform detects that the current page of the customer network management platform is not a circuit topology information display page, that is, a circuit topology display page when receiving an alarm message, the customer network management platform does not process the alarm message at this time. When the user needs to query the circuit information of the optical transport network and send a service query request, after the query process of the cloud network coordinator and the network controller of the optical transport network, the customer network management platform displays the current circuit topology to the user.

In another implementation scenario, if the customer network management platform detects that the current page of the customer network management platform is a circuit topology information display page when receiving the alarm message, the customer network management platform immediately triggers a service query request and sends the service query request to Query to the cloud-network coordinator and the OTN network controller, and display the circuit topology information generated by the cloud-network system controller, so as to automatically update the circuit topology information display page when the circuit path is switched, and update the circuit topology map in real time, improving the Timeliness of circuit topology diagrams.

It should be noted that the OTN circuit information acquisition system also includes the OTN transmission network. In the embodiment of the present application, various service data flows such as network information of the optical transport network, service performance data, and circuit tunnel information are transmitted through the optical transport network transmission network. The OTN transport network may be composed of multiple OTN network devices.

An embodiment of the present application provides a method for acquiring circuit information of an optical transport network. The cloud-network coordinator periodically obtains network information and service performance data of the optical transport network from the network controller of the optical transport network. When the user needs to query the circuit information of the optical transport network, the customer network management platform can receive the user's service query request and forward the service query request to the cloud network coordinator. The cloud network coordinator converts the service name of the OTN circuit carried in the service query request into a universal unique identification code corresponding to the service name, and sends a circuit information query request to the OTN network controller, and the circuit information query request carries the OTN A universally unique identifier for a network circuit. The OTN network controller inquires the UUID of the tunnel corresponding to the OTN circuit according to the UUID of the OTN circuit, and returns the UUID of the tunnel to the cloud-network coordinator. The cloud-network coordinator sends a circuit tunnel information query request to the OTN network controller for querying the circuit tunnel information. The network controller of the optical transport network queries the circuit tunnel information according to the universal unique identification code of the tunnel in the circuit tunnel information query request, and sends the circuit tunnel information to the cloud network coordinator. The cloud-network synergist generates circuit topology information based on circuit tunnel information and OTN network information, and generates OTN circuit information based on circuit topology information and service performance data, and sends OTN circuit information to the customer network management platform. The customer network management platform displays the optical transport network circuit information with an intuitive graphical interface.

In the method provided in this application, the cloud-network coordinator may also subscribe to the OTN network controller for the alarm message of the change of the path role of the OTN circuit and the change of the OTN circuit route. The OTN network controller monitors the path role information of the OTN circuit and whether the OTN circuit route changes. When the path role information of the optical transport network circuit or the route of the optical transport network circuit changes, an alarm message will be displayed to the user through the cloud network coordinator and the customer network management platform, which improves the security of the optical transport network circuit.
