Description
Technical Field
The invention relates to the field of space-to-air communication, in particular to a satellite network management and control protocol semi-physical test device based on an SDN. The device is used for generating a heterogeneous satellite network scene, simulating hardware and simulating a network key technology aiming at a typical satellite task, and a friendly man-machine interaction interface is convenient for a user to realize the requirements of customizing the satellite network scene, viewing a test result and the like.
Background
Software Defined Network (SDN) is a new Network architecture for controlling forwarding separation, and has attracted great interest in applying SDN to spatial information networks due to its flexibility, openness and programmability. If technical research and verification are carried out in a real network system, not only is the period long and the cost high, but also the normal operation of the existing satellite system is possibly influenced, and the experiment of expandability and reconfigurability cannot be carried out. Therefore, in the development of the spatial information network technology based on the SDN, an effective platform and tool for large-scale simulation and experimental verification are urgently needed. However, although the SDN technology is a mature technology applied in the high-throughput wired network, the original simulation tool is not suitable for simulation and test of a satellite scene. The SDN technology was proposed at the beginning of design for the convenience of rapid building of wired test networks by researchers, and then the programmable concept of SDN architecture was paid attention and pursuit by switch manufacturers and developed in core transport networks, for example, the B4 network built by google is the most successful case of SDN technology applied to industrial wired networks. However, the satellite network scenario and the ground cable network scenario have great differences in node resource characteristics, network dynamics, service types, network requirements and the like, and the existing SDN simulation tool (e.g., Mininet) cannot simulate the satellite scenario and cannot meet the simulation requirements of the satellite scenario in the SDN architecture.
Some academic research efforts are now dedicated to developing simulation platforms suitable for SDN management and control technology research in satellite scenarios. The adaptive transformation of a mature SDN simulation tool facing a satellite scene is an idea, researchers complete functions such as topology control, dynamic routing and the like in a satellite network by integrating software simulation tools such as Mininet, STK and the like, however, the simulation function is firstly limited by an integrated software framework by using simple software simulation, and secondly, real data flow cannot be generated, and the authenticity of a result is greatly reduced. Some researchers build a semi-physical simulation platform for inter-satellite dynamic routing research, but the semi-physical simulation platform has the limitations that a host is used for virtualizing an SDN switch and a controller node, an SDN protocol is inevitably simplified, only a simulation test of routing can be realized, and specific task types (such as remote sensing observation and navigation positioning tasks) and other resources (such as computing resources and sensor resources) cannot be simulated. In summary, for a satellite network scene under the SDN architecture, a test platform is required to be designed, which can not only reflect the real physical environment of the satellite network, but also issue and execute the whole process simulation from the user input to the task.
At present, no explanation or report of the similar technology of the invention is found, and similar data at home and abroad are not collected.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
The embodiment of the invention provides a satellite network management and control protocol semi-physical test device based on an SDN (software defined network), which comprises a satellite network simulation system and a network management and control system. The overall architecture of the satellite network management and control system of the device constructed by the invention is shown in figure 1, and the architecture consists of an application layer, a task planning layer, a control layer and a data forwarding layer. The application layer is responsible for constructing various satellite applications such as remote sensing, navigation and the like through a northbound interface protocol. The task planning layer is used as a core layer for user service processing, firstly, diversified user requests are converted into a plurality of workflows according to a uniform user template, a network resource pool is maintained through a virtualization technology, network resources are matched for the workflows according to the real-time resource state of the network, and when a network fails or a certain resource is disconnected, the layer ensures the service quality of the user through service combination replacement. The SDN control layer shields communication details for users, and adaptation of a heterogeneous network can be realized in a customized southbound interface protocol mode. The control layer comprises an SDN controller, a satellite state database, a link information database and the like, wherein the satellite state database stores basic attributes such as satellite ID, loading capacity, noise temperature, orbit parameters, calculation/storage performance and the like; the link information database stores information such as link ID, real-time bandwidth, communication frequency band and the like; the SDN controller is mainly responsible for calculation and flow deployment of network routing, and when a sudden task or network communication fault occurs, the SDN controller realizes regional centralized control. The above layers are all realized by software and deployed in a server, and a data forwarding layer located at the bottommost layer mainly comprises a virtual SDN switch abstracted from a hardware switch and is responsible for realizing the functions of the SDN switch.
The task planning layer can be further divided into a demand planning and scheduling module, a real-time prediction and rescheduling module and an extensible service platform module, and the specific technical architecture and flow are shown in fig. 2.
The extensible service platform module is mainly used for monitoring various base resources in real time, providing optional services for service requirements provided by the task scheduling module, and performing dynamic replacement when the resources are unavailable, as shown in fig. 3. Firstly, the module carries out formalized modeling on various space-based resources, abstracts the space-based resources into various services, and maintains an available service pool according to satellite heartbeat packet data analyzed by the real-time prediction and rescheduling module, namely, discovering new available services, carrying out service registration, updating the current service states, carrying out deletion operation on unavailable services and the like. Based on the maintained available service pool, the expandable service platform module can provide a service selection interface for the task scheduling module, and selects appropriate services from the available service pool to return to an upper layer according to service requirements provided by the task scheduling module, so that the task scheduling module can realize mapping from tasks to the available services; when some services cannot normally provide services due to abnormal conditions, the module can obtain information of the abnormal services and call a dynamic service replacement method, functions meeting the abnormal services through combination of other available services are used by an upper layer, and then results are provided for the real-time prediction and rescheduling module, so that tasks under the abnormal conditions can be normally performed.
The demand planning and scheduling module is shown in fig. 4, and the main work of the demand planning and scheduling module is to convert demands into tasks by configuring a demand description meta-model and a task modeling meta-model, and further describe the tasks into a workflow model with a plurality of subtasks according to the task meta-model, so as to complete the mapping of demands of a single user to the workflow. In order to reduce the number of workflows, the module can form a plurality of workflows according to a plurality of user requirements at a certain time, and then merge the plurality of workflows to merge the same or coverable subtasks. And finally, performing a task scheduling algorithm according to the current available service, and searching the optimal solution of the workflow allocation in the current resource state by calling an interface of the service-capable platform module to complete the mapping from the task to the service.
The real-time prediction and rescheduling model is shown in fig. 5, the real-time prediction module maintains a directed graph of a real-time task completion state for each workflow and updates the directed graph according to monitoring data, then recalculates the remaining working time of the workflow, searches for a bottleneck task of the directed graph in the calculation process, and finally submits a judgment result to the workflow rescheduling module, and the workflow rescheduling module reschedules the bottleneck task of the workflow according to the current resource state, so that the task completion rate of the system is higher.
And the SDN controller in the control layer realizes scene control, network flow optimization deployment and other network performance optimization in a satellite network simulation system. The implementation of the deployment of SDN network traffic can be implemented using SDN controller software that is mainstream today, such as OpenDaylight, opendayright, Ryu, and the like. The invention uses the lightweight Ryu controller software to realize the issuing of the traffic deployment strategy. The work of calculating the traffic deployment strategy is mainly completed by a rate monitoring module and a route calculation module of the SDN controller. The rate monitoring module continuously monitors the flow state of the network, and the routing calculation module can rapidly deploy the routing protocol to be tested by the user. The route calculation module identifies the current network load state by continuously acquiring the network state information from the rate monitoring module, and calculates the current better flow deployment scheme. The scene control is mainly realized by two modules of virtual topology generation and link simulation of the SDN controller, and is used for realizing the functions of broadcast storm suppression, dynamic topology generation and dynamic link configuration.
Aiming at broadcast storm suppression, the invention adopts an ARP proxy mode to process broadcast storms. The controller prestores a host IP address and MAC address mapping table. The switch uploads the ARP request frame to the controller without flooding it according to a preset flow table. When the controller receives the ARP request frame, the controller inquires the MAC address of the target host according to a preset IP-MAC address mapping table, encapsulates the MAC address into an ARP reply frame, and issues the ARP reply frame to the corresponding OpenFlow switch so that the frame is transmitted back to the host sending the ARP request frame.
Aiming at the dynamic topology generation, the invention firstly utilizes STK software to derive the inter-satellite and inter-satellite visible relation and the inter-satellite and inter-satellite link distance at one-minute intervals and stores the result into an excel table. And the virtual topology generation module reads the excel table and constructs a time expansion diagram. The virtual topology generation module can obtain a topology slice at a certain moment and issue a flow table to block part of the ports only by screening each edge according to the time attribute.
For the dynamic link configuration, the invention uses the meter table function of the south-oriented interface protocol OpenFlow v1.3 version to carry out the dynamic configuration of the bandwidth link. The virtual topology generation module firstly reads a distance value between two nodes and transmits the distance value to the link simulation module. And the link simulation module calculates the data transmission rate according to the link model and then sends a corresponding meter table.
In the hardware construction scheme of the satellite network simulation system, the invention uses an SDN switch and a server to simulate a satellite node. The SDN switch is used for simulating a communication transponder on a satellite, and the server is used for simulating computing storage resources and various sensor resources of the satellite. The SDN switches are physically connected in a full connection mode, that is, each switch is connected with any other switch. A hardware construction scheme of the data forwarding layer and a hardware connection scheme between the data forwarding layer and an upper layer are shown in fig. 6, and fig. 6 shows a semi-physical test device construction scheme capable of simulating 4 satellite nodes and large-scale users.
In addition to the construction of the device main body framework and the function module, the invention designs a friendly man-machine interaction interface to facilitate the software interaction of the user of the device. The human-computer interaction interface is based on an vue framework, is constructed by using html and javascript languages, and is mainly divided into three modules, namely satellite constellation visualization display, satellite state information visualization display and task execution process visualization display, and the human-computer interaction interface can realize the functions of network state information visualization display, network performance analysis and the like.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes and modifications may be made by those skilled in the art within the scope of the appended claims without departing from the spirit of the invention.
