(2) switches with TOPO proprietary protocol, for simplicity of presentation, are replaced with "visual switches";
(3) and (3) logging in a WEB page and clicking a visual switch of the visual view, and replacing the visual switch with a WEB switch for simplifying the expression.
Example 1:
the visualization device expressed by the invention generates the visualization view by the visualization view function software, wherein the visualization view function software comprises local area network equipment information acquisition and data arrangement software, an information storage database, WEB view display software and the like.
The local area network equipment information acquisition and data arrangement software comprises ARP protocol information acquisition software, LLDP protocol information acquisition software, UPNP protocol information acquisition software, ONVIF and other network equipment protocol information acquisition software and TOPO private protocol information acquisition and data arrangement software.
ARP protocol software is used for obtaining IP and MAC of online equipment in the network; the LLDP protocol software is used for acquiring information such as MAC, equipment name, port information, management IP and capability value of online equipment in the network; the UPNP protocol information acquisition software is used for acquiring the equipment types of online equipment in the network, including routing equipment, wireless AP equipment, IPC equipment and the like; network equipment protocol software such as ONVIF is used for acquiring equipment type information of specific equipment, such as equipment such as a network camera, a video encoder and a network-based electronic access control system; the TOPO private protocol information acquisition and data arrangement software is used for arranging and transmitting network hierarchical relation data between 'visual switches'. Data acquired by network device protocols such as an ARP protocol, an LLDP protocol, an ONVIF protocol and the like are basic input data, the protocols are network general protocols, basic information of each device in a local area network can be acquired, a visual view can be preliminarily formed by the basic information, and the view network hierarchy is disordered. The TOPO private protocol is the visual view key protocol, the protocol integrates input basic data, establishes a network hierarchy relationship, adds equipment self-defining information, and generates a visual view by data processed by the TOPO private protocol, and the view network hierarchy relationship is accurate and basically consistent with an actual network structure.
The information storage database comprises a simple SQLite3 database and part of software for adding, deleting, modifying and searching the data acquired by the TOPO private protocol.
The WEB view display software comprises transmission software for transmitting data from a background to WEB and view software for displaying network hierarchical relation by a WEB end according to data arrangement.
The present embodiment may also implement corresponding functions through other functional modules.
As shown in fig. 2, the data obtained by the ARP protocol is broadcasted when the network device is connected to the local area network, and is obtained by the network device; the data acquired by the LLDP protocol can be acquired only when the LLDP protocol is started by the device displaying the visual view, and the data transmitted by other devices in the network through the LLDP protocol can be acquired; the data acquired by the UPNP protocol needs network equipment to support the UPNP protocol and is started; the data acquired by the network equipment protocols such as ONVIF and the like can be displayed only by the equipment displaying the visual view by starting the network equipment protocols such as ONVIF and the like by the corresponding equipment in the network; the data acquired by the TOPO private protocol can only be acquired from a visual switch; and the equipment displaying the visual view arranges the received other four types of data through a TOPO private protocol so as to arrange a tree network structure taking the current login equipment as a root node. The tree-shaped network structure is stored in an SQLite3 database, a network structure relation view can be displayed in a visual view of a WEB login page of a visual switch, partial data of each device in the view can be modified, remote login operation can be carried out on partial devices capable of remotely logging in, and monitoring and management are convenient and fast. If network device protocols such as the LLDP protocol or the ONVIF protocol are not started, the information of each device in the visual view is correspondingly reduced, and the network structure is correspondingly inaccurate.
The detailed operation and operation process of the invention are as follows:
firstly, establishing a database and acquiring ARP protocol data.
After the 'visual Switch' with the function of the invention is powered on and started, firstly, a local Network TOPO hierarchical relation database is created, and the Switch information (including device MAC (device MAC address, MAC for short) and father MAC (MAC of the upper-level device in the TOPO Network hierarchical relation), device IP (device IP address, IP for short), device name (partial device self-contained device name), device name (TOPO private protocol self-defined device name), device type (partial device self-contained Router, Switch, Access Point, Access Controller, IP Camera and other types of information) is inserted, the TOPO private protocol additionally defines the device types of Server, Network Video Recorder, PersoComputer and the like), online state (online/offline state), device sending protocol data port (sending port for short), the parameter records the sending port name of the device sending data to the upper-level device in the Network TOPO hierarchical relation, part of the devices do not have a sending port), and a receiving protocol data port (called a receiving port for short) of the upper-level device. The parameter records a receiving port name of the upper-level device in the network TOPO hierarchical relationship for receiving data sent by the device, and a network hierarchical identifier (hierarchical identifier for short) of the device relative to the root device. This parameter plays a key role in processing of device information identified by ARP in return data received from a downward cascade "visual switch"), and the like, and since the current device is the root device by default, the parent MAC of the device is set to 0000.0000.0000, the transmission port and the reception port are empty, the hierarchical identifier is 0, and other information is the switch own information). The switch receives basic information (including MAC, IP and the like) and receiving ports of each device in the local area network through ARP, and after receiving the information, the device writes the data and information such as father MAC (the switch MAC), online state, level identification (level identification is 1) and the like into a database. When the equipment is off-line and on-line, updating the on-line state of the corresponding equipment in the database, and deleting the data of the off-line equipment after a certain time or manually clearing the data of the off-line equipment.
And II, acquiring protocol data such as LLDP, UPNP, ONVIF and the like.
The visual switch defaults to receive UPNP and ONVIF protocol messages, and receives LLDP messages if the LLDP function of the switch is opened. After ARP information is written into a database of a visual switch, the switch analyzes received protocol data such as LLDP, UPNP, ONVIF and the like to obtain data required by the database according to a corresponding message format, and then updates information such as equipment names, equipment types, sending ports, receiving ports and the like of each equipment in the database according to MAC addresses. The acquired network TOPO has only two-layer relation at this time, namely the switch and equipment which can be identified by the switch through ARP. The current state is after the switch is powered on and started and before the visual request of the WEB page is triggered.
And thirdly, sending a TOPO private protocol data acquisition request by the WEB switch.
Logging in a WEB page of a visual switch, clicking a visual view, and triggering a visual request, wherein the WEB switch has four actions in sequence at the moment: sending TOPO data requests, receiving return data of response requests of all the visual switches, sorting network TOPO hierarchical relation, and returning the network TOPO hierarchical relation data to the WEB page. The method comprises the steps that a switch firstly sends a TOPO private protocol request message to each port of the switch, wherein the message comprises the IP of the equipment and the hop count (the hop count is the number of times of forwarding the request message by a visual switch, the initial value of the hop count is 0, the hop count is added with 1 when the request message is forwarded by the visual switch once, the hop count is used for identifying the network level (each visual switch replies to data of a WEB switch and comprises the hop count, and when each piece of equipment information in the replied data is inserted into a WEB switch database, the hop count is added with 1 to replace a level identifier in non-root equipment information) and a control message forwarding range.
And fourthly, returning TOPO private protocol data by each visual switch.
After the visual switch under each port of the WEB switch receives the request message, the hop value in the request message is increased by 1, the corresponding visual switch forwards the request to all ports except the receiving port, meanwhile, the hop value and the local database information are encapsulated into a UDP message, the device IP in the request information is taken as a target IP, the message is replied to the WEB switch requesting the data in a unicast mode, and the like, and the reply message is sent to each visual switch in the downward cascade. After receiving each reply message, the WEB switch carries out data arrangement.
Fifthly, the WEB switch arranges the TOPO hierarchical relation of the network.
After receiving a reply message, namely data acquired by a TOPO private protocol, a WEB switch inserts or updates information of each device in the message into a local database according to an MAC address, and for a root device in the reply message, a parent MAC covering corresponding device information in an original database is the MAC address of the last device for forwarding the TOPO private protocol request message, and covers and updates information of other devices; and updating the hierarchy identifier of the non-root equipment in the reply message to be that the hop value in the reply message is added with 1, and covering and updating partial equipment information. At this time, a more accurate network hierarchy relationship is formed.
The principle of forming the TOPO hierarchy of the network is as follows:
before the WEB switch is powered on and logs in a WEB page, the two-layer TOPO relationship can be obtained through protocols such as ARP, LLDP, UPNP, ONVIF and the like, at the moment, the network hierarchy relationship is not accurate, and part of equipment can be a third layer or even a fourth layer in an actual network. At this time, network hierarchy relationship optimization needs to be performed in cooperation with data such as MAC, parent MAC, transmitting port, receiving port, hierarchy identifier and the like updated in the "data acquired by TOPO private protocol". The network hierarchy of each device can be preliminarily divided by the parent-child relationship of the MAC and the father MAC (at the moment, the hierarchical positions of the devices identified by the ARP of the upper and lower visual switches can be inaccurate); the sending port and the receiving port can make different levels of parent-child relations explicit to the ports; the hierarchical identification can clarify the network hierarchical position of the equipment which is simultaneously identified by the upper and lower levels of visual switch ARP in the actual network. According to the MAC, the father MAC, the sending port, the receiving port and the level identification which are updated after the data acquired by the TOPO private protocol are received, finally, a basically accurate tree-shaped network TOPO level relation taking ' WEB switch ' as a root ' can be formed.
And sixthly, returning network TOPO hierarchical relation data to the WEB by the WEB switch.
The MAC of the WEB switch is taken as a root, recursive operation is carried out on the equipment information of the database according to the relation between the MAC and a father MAC, the data format obtained by the recursive operation is shown as the upper half part of figure 2, the data obtained by the recursive operation is packaged into a CJSON format, and the data is sent to the WEB through an HTTP protocol. After the WEB page acquires the data, the data is analyzed, and a network TOPO hierarchical relationship diagram is generated according to the 'parent-child relationship' of the MAC and the parent MAC, namely 'reverse recursive arrangement of the data', as shown in the lower half of fig. 2, and is finally displayed on the WEB page.
And seventhly, modifying the information of the network equipment.
If the protocol switches are not started, each network device can only acquire basic device information through the ARP, so that TOPO information is incomplete in a visual view of a WEB page, and the device types of devices which cannot be accurately identified can be manually set. In addition, the device name can be set according to the actual network environment, so that the device can be conveniently checked by workers. The modified equipment type and equipment alternative name are stored in a local database, and are only displayed on a WEB page of the WEB switch when the visual view is refreshed. Therefore, the visual view with the hierarchical relation of all the devices of the local area network and accurate basic information is completely finished.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. compared with the traditional method and device for judging the network structure through an SNMP or LLDP mode, the method and device for visualizing the small and medium local area network structure based on the WEB page display and monitoring of the switch have the advantages of more intuitive network structure, simple function operation, convenience for non-professional management and the like.
2. The invention adopts TOPO private protocol combined with SQLite3 database to arrange basic information of devices in network, so that the whole network structure is integrated in a graph, and local area network devices are conveniently monitored and managed.
The above-described embodiments are intended to be illustrative, and not restrictive, of the invention, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
