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.

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.
