The invention is based on a cloud-edge-end network topology structure, adopts a layered network management method, and divides the whole network management into 2 hierarchical levels. And each side is taken as a unit, each side is provided with a manager, the manager only manages the peripheral devices, and the cloud manager is positioned at the higher layer of the side manager and is responsible for collecting the information of each side manager. The management structure has the characteristics of multi-layer management and has good expandability and scalability. Under the condition that the network scale becomes large, tasks are dispersed to the side managers by increasing the number of management sides and increasing the number of side managers, and original information is filtered by the side managers and then transmitted to the managers on the upper layer, so that the management load of the network managers can be balanced, the transmission quantity of the management information on the network can be reduced, the network burden is reduced, and the network bandwidth is saved.
In the prior art, a centralized network management mode is adopted, and all network management tasks are centralized on a manager, which also causes the bottleneck problem of network management: all original data of the agent are sent to a manager, a large amount of data packets with management information can be transmitted in a network, and the transmission occupies large bandwidth and is easy to cause network blockage; all data analysis and calculation are centralized on a manager, so that the calculation load of the manager is too heavy, and the working efficiency and the network management performance are seriously influenced; once the manager fails, the whole network management system is crashed, and the reliability is low.
In network management, a basic model, Manager/Agent (M/a) model, is typically used to build a network management system. Network management systems generally consist of four parts: one or more network managers (or network management workstations), one or more network management agents, one or more management information bases, MIBs, and network management protocols. The Network management agent and the MIB reside together in managed devices or Network Elements (NEs), which are important components in the Network, such as routers, switches, hubs, and the like. The basic model of network management is shown in fig. 1.
The network manager is the core of the entire network management system and is also the entity that performs network management activities. The system is mainly responsible for issuing an operation command of a network manager to a network management agent, receiving response and notification information from the network management agent, and displaying or reporting the response and notification information to the manager. The network management agent of the managed device is software and is mainly responsible for setting corresponding parameter information for the device according to the operation command of a network manager and providing the management information of the device for the network manager. The management information base MIB is a conceptual data repository containing conceptual data constituting management information. It is composed of many management objects and their attributes in the system, such as configuration information, security information, device manufacturer's unique information, etc., and the whole work of network management is to set and read these objects and their attribute values. The network management protocol is the basis of network management and describes communication protocols for information exchange security control between a network manager and a network management agent, which are used to transfer management information data.
Simple Network Management Protocol (SNMP), established by the Internet Activity Board (IAB), is a protocol used by the Internet organization to manage Network Management of the TCP/IP Internet and ethernet. SNMP achieves the goal of network management mainly by a manager polling the agents, setting some keywords and monitoring some network events. SNMP is a TCP/IP protocol centralized application layer protocol, UDP is used as a transmission protocol, and because UDP provides connectionless service, SNMP does not need to maintain connection between a manager and an agent, so SNMP does not require the reliability of messages and does not ensure whether the messages can arrive correctly. Therefore, the manager needs to periodically poll each agent by sending a request message to acquire management information in each MIB, and meanwhile, the manager also receives a Trap message sent by the agent and records the Trap message in a data file. The agent program of each node resides in the workstation memory and is responsible for collecting the network state information of the managed object.
In the existing implementation scheme, network management based on the SNMP technique mainly adopts a centralized network management mode. Generally, the system consists of a network management station and a plurality of managed devices, as shown in fig. 2. The network management station carries out the interaction of management information with the network management agent of the managed equipment through a network management protocol. If the managed device does not contain a network management agent or does not support the network management protocol, the protocol conversion is completed by entrusting the network management agent, and the network management station completes the management of the managed device through the entrusting agent. All network management agents or proxy network management agents work with the network management station under the monitoring and control of the network management station to realize the centralized management of the network. The centralized network management structure has the advantages of simple structure, easy realization and centralized management, and network managers can effectively and globally manage the whole network by controlling managers, so the centralized network management structure is very suitable for small local area networks.
And (4) a layered network management mode. Generally consists of a network management station and several management domains, as shown in fig. 3. According to the cloud-edge-end network architecture, the whole network management is divided into two levels. Setting a 'cloud manager' and a 'side manager', wherein the 'cloud manager' is a manager of the 'side manager'; the "edge manager" forms "domain management" for a plurality of managed "end devices" in units of domains, the management domain is generally divided according to the distribution situation or the functional property of the managed devices, and one management domain includes a plurality of managed devices- "end devices". The "cloud manager" is located at a higher level of the "edge manager" and is responsible for collecting information of each domain managed by each "edge manager". Each client monitors and controls all managed devices in the own area according to the defined management domain, and provides the information of the managed devices to the server respectively. The server stores the management information from each client in a centralized manner and completes various application functions according to the information.
The cloud manager interacts with the access service management equipment in the comprehensive access hotspot through a standard SNMPv2 protocol, and the access service management equipment in the comprehensive access hotspot interacts with an SNMP agent of the terminal through an SNMPv2 protocol. In the whole protocol stack, the end-to-end transport layer protocol adopts UDP, the network layer protocol adopts IP, and the protocol stack is as shown in fig. 4.
The cloud-edge-end based network architecture is as follows:
and a cloud management layer. The cloud gathers various space-based data to a ground cloud end through satellite intercommunication of the existing ground gateway station and a space section, intelligently fuses and processes multi-source data through data monitoring and processing software deployed at the cloud end, and performs multi-level presentation. The cloud end has the capability of controlling and scheduling, and gives command and control commands to the edge, the end and the personnel and equipment connected with the cloud network, so that remote control is realized. The network management system of the 'cloud' end is responsible for the working mode and resource scheduling of the whole satellite and ground wireless communication in the gateway, and provides a plurality of business services such as commands, voice, data, video, internet access, remote command control and the like for end users. The database service module of the cloud management layer is used for storing data, so that the network state and the data of the sides and the ends can be conveniently analyzed, the management interface provides an API (application program interface) which is compatible up and down, and the uploaded data format and the interaction process are unified.
And an edge management layer. The 'side' has the 5G communication, ad hoc network, Internet of things and satellite communication and remote sensing data receiving capacity, is a comprehensive information system integrating various communication means and various access systems in the far, middle and near, and realizes effective and reliable transmission of earthquake disaster multi-sensor information and communication between on-site people, rescue teams and front and rear command centers. Meanwhile, the edge calculation is based on multi-mode comprehensive transmission equipment, has data calculation and data storage capabilities, is responsible for local real-time processing and execution of data information acquired by an opposite end, and provides high-value data for a cloud. In addition, an "edge" has intelligent gateway capabilities for interconversion of multiple communication protocols. The intelligent transmission of the data is realized by judging and analyzing the data sources of the current end and the cloud and selecting a corresponding communication means. The architecture is shown in fig. 5.
The cache table of the edge management layer provides a temporary cache area for network management information and state information, and each accessed record or TRAP notification record is recorded in the cache table. Each record in the cache table includes five fields: node address (NodeID), record name (1istName), actual value (Validvalue), latest update time (Lastupdatetime), and validity time (Validtime). The latest update time indicates the time the record was last updated, either by administrator access or TRAP notification. The validity time, the flag used to determine whether the record is invalid, is a configurable time value.
And the polling mechanism is responsible for circularly inquiring the cache table, calculating the difference between the current time and the latest updating time of the record every time one record is inquired, and if the difference is greater than or equal to the effective time in the record, indicating that the record in the cache table is invalid and indicating that the record should be updated with the latest data or state.
And (4) end equipment. The terminal is a data acquisition terminal such as various deployed sensors, cameras and Beidou positioning terminals, and a communication terminal such as a 5G mobile phone and an ad hoc network. The end device has communication capability with the multi-mode communication device and the cloud. The end equipment can be used as an information sender to gather various information to a side end and a cloud network, and can also be used as an information receiver to receive control commands of corresponding cloud command, such as closing a sensor, rotating a camera and the like. The end equipment layer is mainly responsible for measuring actual data and controlling. TRAP mechanism, which is used to report real-time status of the network to the gateway or administrator at irregular time, as well as the actual sensing data. And the control and sensing function is used for matching with the request of the manager, realizing the corresponding reverse control function and responding to the request operation sent by the manager.
The specific operation flow of the hierarchical management scheme is shown in fig. 6.
(1) Query or setup request
The manager sends a request to the lower layer through operations such as GET, SET and the like of the SNMP, can perform remote connection and transmission through the internet, and obtains information required by the manager through such operations or sends a control request to the sensing node.
(2) Polling mechanism and caching mechanism
The edge manager (gateway) is not only a channel between the upper manager and the lower sensing layer, but also provides reference basis for sensing data and network state through the cache table, so that the response time can be reduced. If the data in the cache table is not invalidated due to time-out, the data in the cache table can be used for reducing the communication traffic in the wireless sensor network. When the gateway receives the SNMP request of a manager, the SNMP request is stored in a temporary queue 1, an MIB is inquired, a corresponding object identifier is matched and converted into an SNMP message without an identifier prefix, the SNMP message is stored in a temporary queue 2, then the updating time and the effective time of corresponding data in a cache table are inquired, if the time is out, the SNMP request message in the temporary queue 2 is sent to a corresponding end node to obtain the data or the state, then the data or the state is returned to the manager, the cache table is updated simultaneously, if the time is not out, the data in the cache table is directly obtained, and the SNMP request message in the temporary queue 1is responded. The polling mechanism of the gateway can continuously inquire two times in the cache table, and when an out-of-date state or data is found, a GET request is actively sent downwards to update the cache table.
(3) TRAP mechanism
In the end equipment layer, the TRAP mechanism of the equipment can continuously send sensing data and network states to the gateway layer, the auxiliary gateway establishes a cache table and updates the cache table, and the TRAP mechanism can receive a request instruction or a control instruction from an upper layer and acquire or control bottom equipment data and a controller. The TRAP mechanism can be briefly analyzed, responds to the network state, and immediately sends an announcement message upwards if the network state is unstable or the sensing equipment is abnormal.
And (3) application of Round Trip Time (RTT). With the help of inter-satellite links (ISLs), global services can be realized without deploying gs (gateway station) on a global scale. However, the RTT is low near the GS area. A global side network map of the communication satellite of the system is established, namely a map of round trip time RTT between a satellite signal receiving device connected with a side manager and a low-orbit satellite. As shown in the figure, different color block depths represent RTT ranges in different intervals, and the RTT ranges may be constructed according to actual measurement of the position of the satellite receiving antenna, or may be constructed in a theoretical estimation manner. For example, it is considered to estimate or predict the RTT by the earth radius or the like in a constellation scene, network coverage, or the like. The present invention directly uses the CCF to be equal to the area division of RTT by simplifying the equivalent mode.
Wherein T represents the number of satellites, REIs the radius of the earth and the radius of the earth,
is the geocentric angle of coverage provided by each satellite, determined by the orbital altitude and the minimum elevation angle. As shown in fig. 7 and 8, the graphs obtained by calculating each region one by one are substantially close to the RTT graph, and can be directly used, thereby saving calculation power in real time. When the CCF is greater than 0.4, the frequency of the reduced polling is 50% or more of the normal preset. The distribution of RTT values after the implementation of the present technical solution is shown in fig. 9, where it can be seen that the RTT is improved in a transition region where the original RTT changes from strong to weak. The regions with higher RTT have no significant change or improvement due to the bad signal.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the invention, and it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention.
