An optical transport network (Optical Transport Network, OTN) is a type of transport network, referring to a transport network that enables transport, multiplexing, routing, monitoring of traffic signals within an optical domain and ensures its performance index and survivability. The OTN takes the wavelength division multiplexing technology (Wavelength Division Multiplexing, WDM) technology as a basis, ensures the ultra-large transmission capacity and simultaneously adds stronger operation, maintenance and management capabilities of a synchronous digital hierarchy (Synchronous Digital Hierarchy, SDH). OTN inherits many advantages of SDH and WDM technologies, and has become the dominant technology of the current industry optical transport network. The optical transport network can provide flexible architecture and differentiated services for operators in the era of IP (Internet Protocol ) and optical convergence under the condition of fully utilizing transmission basic equipment resources.

The traffic performance data may include one or more of the following: bandwidth utilization, traffic index, packet loss index, jitter index, etc. of the optical transport network circuit. For example, the period of periodically acquiring the service performance data by the cloud network coordinator to the optical transport network controller may be 15 minutes.

And the cloud network coordinator periodically acquires the network information and the service performance data of the optical transport network from the optical transport network controller, and then stores the network information and the service performance data of the optical transport network into a cloud network coordinator database.

In one implementation scenario, if the cloud network coordinator cannot query the network element information through the optical transport network controller, the cloud network coordinator may further query the resource management system for the network element information.

S402: and the client network management platform receives a service query request of a user and forwards the service query request to the cloud network coordinator, wherein the service query request carries a service name of an optical transmission network circuit.

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

The user can actively inquire the circuit information of the optical transport network. In one implementation scenario, when a user needs to query the optical transport network circuit information, the user may input a service name of the optical transport network circuit and send a service query request at the client network management platform, so as to obtain the optical transport network circuit information.

S403: the cloud network coordinator sends a circuit information inquiry request to the optical transport network controller, wherein the circuit information inquiry request carries a universal unique identification code corresponding to the service name of the optical transport network circuit.

Before the cloud network coordinator sends a circuit information inquiry request to the optical transport network controller, the service name of the optical transport network circuit carried by the service inquiry request needs to be converted into a universal unique identification code of the optical transport network circuit for identification of the optical transport network controller.

S404: the optical transport network controller inquires the universal unique identification code of the tunnel corresponding to the optical transport network circuit according to the universal unique identification code of the optical transport network circuit, and returns the universal unique identification code of the tunnel to the cloud network coordinator.

Different optical transport network circuits correspond to different tunnels, and the corresponding optical transport network circuit can be determined by the universal unique identification code of the optical transport network circuit, so that the tunnel corresponding to the optical transport network circuit can be determined by the universal unique identification code of the optical transport network circuit. The universally unique identification code of the tunnel can be used as the identification information of the tunnel.

S405: the cloud network coordinator sends a circuit tunnel information inquiry request to the optical transport network controller, wherein the circuit tunnel information inquiry request carries a universal unique identification code of a tunnel.

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

S406: and the optical transmission network controller inquires circuit tunnel information according to the universal unique identification code of the tunnel 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 may indicate that the current path is a working path or a protection path, and thus the path running state information includes working path running state information and protection path running state information. The network element ID information includes network element ID information of the working path and network element ID information of the protection path. The path end-to-end one-way delay information is the working path end-to-end one-way delay information.

In one implementation scenario, the circuit tunnel information is in JSON (JavaScript Object Notation, JS object numbered musical notation) or XML (Extensible Markup Language ) format, so after the cloud network coordinator receives the circuit tunnel information, the cloud network coordinator needs to analyze the circuit tunnel information.

S407: the cloud network coordinator generates circuit topology information according to the circuit tunnel information and the optical transport network information, generates optical transport network circuit information according to the circuit topology information and the service performance data, and sends the optical transport network circuit information to the client network management platform.

The cloud network coordinator database contains network information and service performance data of the optical transport network. The network information and the service performance data of the optical transport network are obtained from the network controller of the optical transport network periodically before the cloud network coordinator receives the service inquiry request.

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

The flow index can display the uplink flow and the downlink flow of the optical transport network circuit separately, and the flow index comprises a flow index and a historical flow change in the last acquisition period, wherein the historical flow change can be a flow change in one week. The current and recent flow conditions of the optical transmission network circuit can be mastered in time according to the flow index, so that the capacity expansion time of the optical transmission network circuit is determined, and the accuracy and timeliness of capacity expansion are improved.

The packet loss index can be the maximum value of the uplink packet loss rate or the downlink packet loss rate of the optical transmission network circuit. The jitter index may be the maximum value of the upstream jitter or the downstream jitter of the optical transport network circuit.

The process of the cloud network coordinator generating the circuit topology information according to the circuit tunnel information and the optical transport network information is described in detail in the above embodiments, and will not be described here again.

S408: the customer network management platform displays the optical transmission network circuit information by an intuitive graphical interface.

The client network management platform displays the circuit information of the optical transmission network by an intuitive imaging interface, and is clear and intuitive. For example, the circuit topology information in the optical transport network circuit information may be generated into a circuit topology diagram, which is shown to the user, and may be referred to as fig. 5. Fig. 5 is a circuit topology diagram of a point-to-point cloud circuit.

In one implementation scenario, path running state information included in the optical transport network circuit information is two running states of up and down, where up represents a path as a normal running state, and down represents a path as an interrupt state. The client network management platform can distinguish the path running state by using different colors. For example, a path that is operating normally is displayed green and a path in an interrupted state is displayed red.

Because the optical transmission network circuit can be connected into the cloud pool, a user can fuse the cloud pool and the optical network according to the optical transmission network circuit information displayed by the client network management platform, and the efficiency of the fusion of the cloud pool and the optical network is improved.

S409: the cloud network coordinator subscribes an alarm message of path role change of the optical transport network circuit and route change of the optical transport network circuit to the optical transport network controller.

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

Taking the path role change of the optical transport network circuit as an example, since the path role information of the optical transport network circuit includes the working path and the protection path, the working path and the protection path can be switched. When the working path fails, the protection path is switched to the working path, i.e. the path role of the initial protection path at the moment is the working path.

S410: the optical transport network controller monitors path role information of the optical transport network circuit and whether the optical transport network circuit route changes.

In one implementation scenario, when the optical transport network controller monitors that the path role information of the optical transport network circuit or the optical transport network circuit route changes, an alarm message is sent to the cloud network coordinator. And the cloud network coordinator waits for a certain time until the optical transmission network circuit is stable, and then sends an alarm message to the client network management platform.

In one implementation scenario, if the client network management platform receives the alarm message, it is detected that the current page of the client network management platform is not the circuit topology information display page, that is, the circuit topology diagram display page, then the client network management platform does not process the alarm message. When a user needs to inquire the circuit information of the optical transmission network and send a service inquiry request, the client network management platform displays the current circuit topological diagram to the user after the inquiry process of the cloud network coordinator and the optical transmission network controller.

In another implementation scenario, if the client network management platform receives the alarm message, it is detected that the current page of the client network management platform is a circuit topology information display page, then the client network management platform immediately triggers a service query request, sends the service query request to the cloud network coordinator and the optical transmission network controller for query, and displays the service query request according to the circuit topology information generated by the cloud network coordinator, so that the circuit topology information display page is automatically updated when the circuit path is switched, the circuit topology diagram is updated in real time, and timeliness of the circuit topology diagram is improved.

It should be noted that the optical transport network circuit information acquisition system further includes an optical transport network transmission network. In the embodiment of the application, various service data flows such as network information, service performance data, circuit tunnel information and the like of the optical transport network are transmitted through the optical transport network. The optical transport network transmission network may be constituted by a plurality of optical transport network devices.

The embodiment of the application provides an optical transport network circuit information acquisition method. The cloud network coordinator periodically acquires network information and service performance data of the optical transport network from the optical transport network controller. When the user needs to inquire the circuit information of the optical transmission network, the client network management platform can receive the service inquiry request of the user and forward the service inquiry request to the cloud network coordinator. The cloud network coordinator converts the service name of the optical transport network circuit carried by the service inquiry request into a universal unique identification code corresponding to the service name, and sends a circuit information inquiry request to the optical transport network controller, wherein the circuit information inquiry request carries the universal unique identification code of the optical transport network circuit. The optical transport network controller inquires the universal unique identification code of the tunnel corresponding to the optical transport network circuit according to the universal unique identification code of the optical transport network circuit, and returns the universal unique identification code of the tunnel to the cloud network coordinator. The cloud network coordinator sends a circuit tunnel information inquiry request to the optical transport network controller, and the circuit tunnel information inquiry request is used for inquiring the circuit tunnel information. And the optical transmission network controller inquires the circuit tunnel information according to the universal unique identification code of the tunnel in the circuit tunnel information inquiry request and sends the circuit tunnel information to the cloud network coordinator. The cloud network coordinator generates circuit topology information according to the circuit tunnel information and the optical transport network information, generates optical transport network circuit information according to the circuit topology information and the service performance data, and sends the optical transport network circuit information to the client network management platform.
