2. Detailed description of the preferred embodiments
The realization of the network access equipment full life cycle management software platform under the power communication data network environment adopts the following scheme:
2.1 deployment of servers
And respectively deploying each application service to different application servers by adopting an independent server deployment mode, namely respectively deploying the database server, the network data acquisition server and the application service server to different PC servers to form a service group. The processor realizes the mutual coordination of various processors with different functions, shares the peripheral equipment and software of the system, accelerates the processing speed of the system, simplifies the logic structure of the host, is particularly suitable for the automatic control of industrial production lines and the management of enterprises and public institutions, and has low cost and easy maintenance.
2.2 data database installation and design
The software tool database adopts a MySQL database. The MySQL database is a relational database management system that keeps data in different tables instead of putting all data in one large repository, which increases speed and flexibility. The software is free, simple to install, convenient to operate and easy to maintain, and is the first choice of small and medium-sized enterprises or websites. In order to collect terminal device information more comprehensively and provide support for daily operation and maintenance, a plurality of tables are designed, and various terminal data are included as much as possible.
Table name table use
DEP1 level department NETWORK information NETWORK segment
DEP2 two-level department SCANLOG scan log
Management of USERPASS users of DEVALL terminal equipment
MAINLOG operation and maintenance log VPN/VLAN VAPN/VLAN information
2.3 scanner development
The software tool scanner uses SNMP protocol to perform discontinuous polling on information equipment and reads ARP table data, thereby effectively monitoring the running state of the equipment. SNMP is an application protocol that uses UDP encapsulation for transport. UDP is a connectionless transport layer protocol that provides simple, reliable transport services for the fourth layer protocol in the OSI model. SNMPv1 is widely used as a practical network management protocol on the internet. The SNMP V1 is widely used and has low safety, but the data safety is not ensured by a network protocol considering that the data is only collected in a management information area, and the complex network calculation can increase the network load, so the mode adopts the SNMP of V1 version.
2.4 software platform development
The software adopts a Client/Server mode, namely a Client-side Server-side framework, and a Client side of the software comprises one or more programs running on a computer of a user. The C/S framework has rich interfaces and operations and high safety, but the access needs to install client software on the terminal, so that the terminal access is limited. Because the information operation and maintenance personnel mainly operate in the information team, the operation and maintenance of the service are not influenced, and the safety of the data is ensured. And since DEPHI is also the main tool language for C/S mode development at present, the full life cycle management tool of the network access equipment is developed by DEPHI.
3. Implementation method
3.1 device scanner
The SNMP protocol is utilized to carry out polling access on the network equipment so as to acquire the latest ARP data, and the specific operation flow is as follows:
1. reading scanning parameters (scanning interval time, snmp parameter, network management equipment IP, etc.)
2. Reading the ARP table of the first equipment by adopting a polling mode, storing the ARP table into a memory if the reading is successful, reading again at an interval of n seconds if the reading is failed (sometimes the reading is failed due to network reasons or equipment reasons), trying for 5 times in total, and polling the next equipment if the reading is failed for 5 times.
3. And after all the devices finish polling, comparing the ARP table entries in the memory with the actual table entries.
Primary code fragment:
the specific operation flow of matching the ARP table entry data in the memory is as follows:
1. and if the IP and the MAC in the memory are identical to the actual IP and the MAC, updating the information of the last online time, the source equipment and the like in the actual table.
2. And if the mac in the memory does not exist in the actual table, determining that the new device is accessed to the network.
3. If the mac in the memory exists in the actual table but the IP is not equal, the user is judged to modify the IP address.
4. If the mac in the memory exists in the database and is marked as network quit equipment, judging that the equipment accesses the network for the second time.
The new equipment, the equipment with changed information and the equipment with secondary network access in the network can be found through the scanning operation of the scanner, so that the new equipment, the equipment with changed information and the equipment with secondary network access are pushed to a network access equipment full life cycle management platform, and operation and maintenance personnel can conveniently carry out service operation.
3.2 network entry operations
General management information large-area equipment is accessed to a network in two situations:
the first is that an information operation and maintenance person actively accesses the network, after the access of one device is completed, the network access operation of the new device can be manually performed, the information of the network access device is recorded to complete the network access of the device, and of course, under general conditions, the device scanner can find the new device access within 15 minutes, and then the device is selected to perform the network access operation.
The second type is a device directly accessed by non-information operation and maintenance personnel, such as a device accessed by substation workers themselves or a device accessed by information operation and maintenance outsourcing personnel, and the device can also find new devices within 15 minutes generally by a device scanner.
After determining that the equipment is accessed to the network, filling basic information of the equipment: the method comprises the following steps of IP address, MAC address, primary department, secondary department, switch IP where the switch is located, VLAN where the switch is located, VPN where the switch is located, switch port where the switch is located, equipment type, installation position, user, wall box, contact telephone, operator, remark and other information, and information input of equipment network access is completed.
Primary code fragment:
4.3 device migration or Change
There are two general cases of migration or change of management information large-area devices:
the first is that the information operation and maintenance personnel change the physical position or the use function of the equipment according to the requirements of a business department, and when the port binding information change and the terminal configuration change of the switch are completed, the information change is completed in a platform equipment migration and change module. In general, the device scanner may find that the device has changed information within 15 minutes, and then select the device for a device information change operation.
The second type is that non-information operation and maintenance personnel directly change the equipment, for example, office workers in each work area adjust the office position by themselves or the information operation and maintenance outsourcing personnel change the application of the equipment on site, and the like, the equipment can discover that the equipment information is changed within 15 minutes generally.
By re-filling or checking the device basic information: the data updating method comprises the following steps of IP address, MAC address, primary department, secondary department, switch IP where the switch is located, VLAN where the switch is located, VPN where the switch is located, switch port where the switch is located, equipment type, installation position, user, wall box, contact telephone, operator, remark and other information, and data updating of the information is completed.
Primary code fragment:

begin
if ADOQuery1.RecordCount<1then exit；
if Trim (ADOQuery1.FieldByName ('status'). AsString) < > 'at net' the exit;
MoveDev.ShowModal；
end；
4.4 Equipment quit Net
In the operation and maintenance process of the daily information terminal, a large number of allocated IP addresses are idle, the use efficiency of the IP addresses is seriously influenced, and therefore the fact that the zombie terminal is cleared in time to release the occupied IP is very necessary for improving the operation and maintenance efficiency.
And inquiring the equipment which has the 'last service time' of the information equipment longer than 6 months, namely equipment which is not used online in 6 months, and then selecting the corresponding equipment to perform network quitting operation to complete the information of the equipment on the network.
Primary code fragment:
4.5 Secondary networking of devices
After the information equipment temporarily exits from the information management large area network for some reason, but re-network again due to business needs in the later period, because network access operation is performed before (the MAC address is not changed), we define the re-network as secondary network access. The second network access operation process of the device is similar to the first network access operation of the device, except that the MAC address can be automatically filled.
By filling in device basic information: IP address, first-level department, second-level department, switch IP, VLAN, VPN, switch port, device type, installation position, user, wall box, contact telephone, operator, remark and other information to complete the secondary network access of device information.
Primary code fragment:
procedure TForm1.Button9Click(Sender:TObject)；
begin
if ADOQuery1.RecordCount<1then exit；
if Trim (ADOQuery1.FieldByName ('status'). AsString) < > 'Net-off' the exit;
ReNewDev.ShowModal；
end
4.6 device queries
The operation and maintenance personnel can inquire the relevant information of the corresponding equipment, particularly the IP address of the switch corresponding to the terminal according to the inquiry conditions of IP, MAC, VLAN, department, switch, port, installation position, user, final use and the like, thereby entering the port where the terminal is located most quickly and inquiring the current operation state of the terminal.
Primary code fragment:
