Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to an open optical network system control method, device, medium and product based on SDN. Background Art

[0002] In recent years, with the rapid development of network technology, the fixed routing and rigid control methods of traditional optical network systems can no longer meet the needs of modern network applications for flexibility and scalability. At present, although software-defined networks (SDN) are used in the field of optical networks, the application of SDN is still in its infancy. This has caused traditional optical network systems to usually adopt fixed routing and control methods, which are not flexible enough when facing changes in network traffic and complex application requirements. However, although some systems have introduced SDN technology, they still have limitations on the control level of optical network equipment, and cannot provide good protection for the traffic of optical network equipment. They can only ensure the accurate transmission and processing of traffic. Summary of the invention

[0003] One purpose of the present application is to provide an open optical network system control method, device, medium and product based on SDN, at least to solve the problem of flow control limitations in the optical network system. The present application obtains the preset priority level of at least one optical network device; identifies the historical flow information of the optical network device in the open optical network system; and optimizes and adjusts the routing path of the optical network device when the response speed parameter of the historical flow information meets the adjustment condition. By adopting this scheme, it can be realized that when the statistical data of the historical flow information of the optical network device does not meet the preset priority level, the routing path optimization strategy for the optical network device is automatically triggered to improve the response speed of the optical network device in the open optical network system. Not only can the SDN controller be used to configure the routing path of each optical network device in the open optical network system, but also specific optimization rules can be set for it, so as to autonomously optimize when the optimization conditions are met when monitoring, thereby improving the flexibility of the control of the open optical network system.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] First embodiment

[0019] The first embodiment of the present application relates to a control method for an open optical network system based on SDN. Figure 1 As shown, the open optical network system includes an SDN controller, an optical network device and an open interface, and the SDN controller is connected to the optical network device via an open interface; the method may include the following steps:

[0020] Step S101, obtaining a preset priority level of at least one optical network device;

[0021] Among them, the SDN controller can be used to separate the control plane from the data plane of the network, and uniformly manage and control the entire network through a centralized controller. The network can be configured, monitored and troubleshooted from a central location, greatly improving the efficiency and flexibility of network management. The SDN controller is programmable and provides a rich programming interface, allowing network administrators and developers to write customized network control programs based on specific business needs. This enables the network to quickly adapt to changing business needs and achieve network automation and intelligence. The SDN controller can be used for traffic management, can monitor the traffic situation in the network in real time, and schedule and optimize traffic according to preset policies. For example, high-priority traffic can be allocated to a better network path to ensure the service quality of key businesses. The SDN controller can support network virtualization technology, divide the physical network into multiple logical networks, and provide independent network resources for different users or businesses. This helps to improve the utilization of network resources and reduce network operating costs.

[0022] The SDN controller communicates with switches, routers and other devices in the network through the southbound interface. The southbound interface usually uses standardized protocols, such as OpenFlow, so that the controller can uniformly manage devices from different manufacturers. The controller receives network requests from upper-layer applications through the northbound interface, such as creating virtual networks and adjusting traffic paths. The northbound interface usually uses open interfaces such as RESTful API to facilitate application developers to call. The SDN controller calculates the corresponding network policy based on the received application requests and network status information. These policies include traffic forwarding rules, network topology adjustments, etc. The SDN controller sends the calculated network policy to the network device through the southbound interface, and the network device forwards and processes traffic according to these policies.

[0023] In data center networks, SDN controllers can achieve efficient communication, load balancing, and fault recovery between servers. By dynamically adjusting network topology and traffic paths, data center resource utilization and service quality can be improved. Operators can use SDN controllers to achieve intelligent management and optimization of networks. For example, network bandwidth can be dynamically adjusted and routing selection can be optimized according to user needs and network traffic conditions to improve network performance and user experience. In enterprise networks, enterprises can use SDN controllers to build flexible and scalable enterprise networks. Rapid network deployment, automated management, and security control can be achieved to meet the ever-changing business needs of enterprises.

[0024] Common open interface types, such as southbound interfaces, are mainly used for communication between SDN controllers and optical network devices. For example, OpenFlow is a widely used southbound interface protocol that allows controllers to perform fine-grained control over traffic forwarding of network devices. Other southbound interfaces include NETCONF, YANG, etc., which provide functions such as device configuration management and status monitoring.

[0025] The northbound interface provides an interface for upper-layer applications and services to interact with the optical network system. Through the northbound interface, applications can request network resources, query network status, configure network policies, etc. RESTful API is a common form of northbound interface, which provides a simple and standardized interface for application developers to use. In addition, the east-west interface is used for interconnection and collaboration between different optical network systems. For example, in a multi-domain optical network, the east-west interface can realize resource sharing and collaborative scheduling between different domains. Standardized east-west interface protocols can promote cooperation between different network operators and improve the efficiency and reliability of the entire optical network.

[0026] Open interfaces allow optical network devices from different manufacturers to communicate and work together. You are no longer limited to the equipment ecosystem of a single manufacturer, but can freely choose the most suitable equipment combination according to your needs, which improves the flexibility and scalability of the system. Open interfaces provide third-party developers with the opportunity to participate in the development of optical network systems. They can use these interfaces to develop new applications, functions and services, and promote the continuous innovation and progress of optical network technology. At the same time, because open interfaces promote market competition, equipment prices are more competitive, while also reducing dependence on a single manufacturer and reducing maintenance and upgrade costs.

[0027] Open interfaces in open optical network systems are the key to achieving openness, flexibility and innovation of optical networks.

[0028] The optical network devices may be devices from the same or different manufacturers. In an open optical network system, the optical network devices may be devices used to receive messages, process data, send messages, and the like.

[0029] In this solution, each optical network device can be set with a preset priority level when joining the open optical network system. For example, the first priority, the second priority, and the third priority, etc. For example, the first priority requires the fastest processing speed, so a shorter routing path can be assigned to it, while the second priority and the third priority can be assigned longer routing paths one by one to adapt to the hardware configuration of the current open optical network system.

[0030] Step S102, identifying historical traffic information of the optical network device in the open optical network system;

[0031] The historical traffic information may be traffic information processed by the current optical network device observed within a certain observation period, such as one week, one month, etc. The historical traffic information may include traffic request type, traffic response time, etc.

[0032] Step S103: When the response speed parameter of the historical traffic information meets the adjustment condition, the routing path of the optical network device is optimized and adjusted.

[0033] For historical traffic information, certain adjustment conditions can be set. For example, if the response time of historical traffic is long during the observation period and cannot meet the preset priority level of the optical network device, the optical network device needs to be optimized, specifically, the amount of processed traffic and the routing path can be optimized.

[0034] In this embodiment, optionally, identifying whether the response speed parameter of the historical traffic information meets the adjustment condition includes:

[0035] Obtaining a response speed parameter of the historical traffic information;

[0036] Identify whether the statistical value of the response speed parameter is lower than the minimum speed threshold of the preset priority level;

[0037] If it is lower, it is determined that the adjustment conditions are met.

[0038] Among them, the response speed parameter can be used to reflect the speed information in the process of historical traffic processing. For example, it can be the response time of processing historical traffic. The shorter the response time, the faster the speed.

[0039] In the case where it is identified that the statistical value of the response speed parameter is lower than the lowest speed threshold of the preset priority level, it can be determined that the adjustment condition is met.

[0040] Among them, a different minimum speed threshold can be set for each preset priority level, for example, the minimum speed threshold of the first priority level is 5ms, the minimum speed threshold of the second priority level is 20ms, and the minimum speed threshold of the third priority level is 100ms. Then, after counting the response speed parameters, it is found that the average response speed is 8ms, and the priority level of the optical network device is the second priority, then it can be determined that it does not meet the adjustment conditions. After counting the response speed parameters, it is found that the average response speed is 12ms, and the priority level of the optical network device is the second priority, then it can be determined that it meets the adjustment conditions.

[0041] By identifying the response speed parameters, this solution can well determine whether the optical network device is within the normal response speed range of the current priority, so as to automatically discover the optical network device that needs to be optimized, thereby realizing autonomous optimization of the optical network device.

[0042] In this embodiment, optionally, the statistical value of the response speed parameter includes an average value of the response speed parameter of the optical network device within an observation period.

[0043] In order to more accurately identify whether the optical network device meets the adjustment condition, the judgment may be made by calculating the average value of the response speed parameter of the optical network device within the observation period.

[0044] Through such a setting, the present solution can better determine whether the optical network device meets the adjustment conditions, thereby achieving precise control of the optimization of the optical network device and preventing individual erroneous data from affecting the optimization of the optical network device.

[0045] In this embodiment, optionally, identifying whether the response speed parameter of the historical traffic information meets the adjustment condition includes:

[0046] Obtaining a response stability parameter of the historical flow information;

[0047] Identifying whether the statistical value of the response stability parameter is lower than the stability threshold of the preset priority level;

[0048] If it is lower, it is determined that the adjustment conditions are met.

[0049] In another embodiment, the response stability parameters of the historical traffic information can be identified. For example, in the case of a successful response, the score can be calculated based on the response duration. In the case of a failed response, a fixed score can be set and the final score can be finally obtained. Thus, the stability evaluation result of the optical network device can be achieved, and then, whether the optical network device meets the adjustment conditions can be determined based on the evaluation result.

[0050] Through such a setting, this embodiment can evaluate whether the network status of the optical network device meets the current priority level from another dimension, so that when optimization is needed, optimization can be performed according to the monitoring data, thereby ensuring the normal operation of each optical network device in the open optical network system.

[0051] In this embodiment, optionally, the statistical value of the response stability parameter includes a variance of the response duration of the optical network device within an observation period.

[0052] Among them, the statistical value of the stability parameter includes the variance of the response time of the optical network device within the observation period, that is, if the response time fluctuates greatly, it is determined that the adjustment conditions are met and optimization is required, and if the response time fluctuates slightly, it is determined that the adjustment conditions are not met and no optimization is required.

[0053] Through such a setting, this scheme can provide a simple and accurate statistical method for its response stability parameters, avoiding the problem of large amount of calculation of SDN controller caused by complex statistical methods. At the same time, the use of variance can well reflect the network status of optical network equipment.

[0054] In this embodiment, optionally, when the response speed parameter of the historical traffic information meets the adjustment condition, optimizing and adjusting the routing path of the optical network device includes:

[0055] When the response speed parameter of the historical traffic information meets the adjustment condition, optimizing the routing path of the optical network device;

[0056] The optimized configured routing path of the optical network device is sent to at least one routing node on the routing path, and is also sent to the optical network device.

[0057] Among them, when the response speed parameter of the historical traffic information meets the adjustment conditions, the routing path of the optical network device is optimized and configured; for example, the original routing path of the optical network device is: routing node 1-routing node 2-routing node 3-routing node 4. After optimization, it can be configured that the routing path only includes: routing node 1-routing node 2.

[0058] The optimized configured routing path of the optical network device is sent to at least one routing node on the routing path, and is also sent to the optical network device.

[0059] After the optimized configuration is completed, the configuration information can be synchronized to routing node 1, routing node 2 and the optical network device, so that the optimized configuration information can be effectively provided to the optical network device for execution.

[0060] Through such a setting, this solution can improve the optimization effect and realize flexible control of the routing path of the optical network equipment based on the SDN controller.

[0061] Second embodiment

[0062] The second embodiment of the present application relates to a control method for an open optical network system based on SDN. The above embodiment is specifically optimized as follows: the method further includes: obtaining the traffic state in the open optical network system; when the traffic state is a congested state, identifying whether the preset priority level of the optical network device is a target level; if it is the target level, configuring a dedicated routing path for the optical network device to perform routing communication for the optical network device through the dedicated routing path.

[0063] like Figure 2 As shown, the method may include the following steps:

[0064] Step S201, obtaining the flow status in the open optical network system;

[0065] The traffic state in the open optical network system may be a busy state, a medium state, and an idle state. In the busy state, the entire open optical network system may have a large amount of information that needs to be interacted, in the medium state, the entire open optical network system may have a certain amount of information that needs to be interacted, and in the idle state, the entire open optical network system may have very little information that needs to be interacted.

[0066] Step S202, when the traffic state is a congested state, identifying whether the preset priority level of the optical network device is a target level;

[0067] When the traffic state is a congested state, it is identified whether the preset priority level of the optical network device is the first priority level, wherein the highest priority level can be determined as the target level, because the first priority level needs to ensure the communication response speed.

[0068] Step S203: If it is the target level, a dedicated routing path is configured for the optical network device to perform routing communication for the optical network device through the dedicated routing path.

[0069] In the case of the first priority or the highest priority, a dedicated routing path can be configured for the optical network device. For example, the routing paths of all the bottom priority optical network devices are switched to only routing node 1, and the routing node 1 does not participate in the information routing of other optical network devices in the open optical network system, thereby obtaining a dedicated routing path to perform routing communication for the optical network device through the dedicated routing path.

[0070] Based on the above embodiments, this embodiment provides a solution for optimizing the routing path of the optical network device in combination with the current traffic status in the open optical network system, thereby ensuring that the optical network device with the highest priority in the open optical network system can have a good communication effect.

[0071] This solution provides an open optical network system based on SDN and its intelligent routing control method to enhance the flexibility, scalability and intelligence level of the network, so as to better adapt to the ever-changing network environment and meet complex application requirements. Specifically, this solution constructs an open optical network system based on SDN, including an SDN controller, optical network equipment and an open interface. The SDN controller is responsible for the global network view and control logic, and can dynamically adjust the routing and forwarding strategies of the optical network equipment. The optical network equipment communicates with the SDN controller through an open interface, receives and executes control instructions. In addition, this technology also proposes an intelligent routing control method, which dynamically optimizes routing selection based on real-time monitoring and analysis of network traffic to achieve more efficient network transmission and lower latency.

[0072] Compared with other technologies, this solution realizes the openness and programmability of the optical network system by introducing SDN technology, greatly improving the flexibility and scalability of the network. At the same time, the intelligent routing control method can dynamically adjust the routing strategy according to the actual network traffic, effectively improving the network transmission efficiency and response speed.
