A Group Network System And The Design And Implementation Of Network Management

Stepping into the21st century, informationization is more and more demanded by enterprise. People will face the problem that how to build a high-quality Enterprise Campus Network. Enterprise information refers to the use of computer technology, network technology and database technology, business process optimization, control and integrated management of enterprise production and management activities of the various production information, effective utilization and sharing of enterprise internal and external information, thereby improving the economic efficiency of enterprises and market competitiveness, enterprise information related to the innovation of enterprise management, management process optimization of the reorganization, management team and innovation of managing means.This thesis has designed and built a high-speed, secure and stable Network System Platform for Group, with the aid of the Computer Network Principle, the principle of Network Design, LAN and network security technology. This design has used the hierarchical Network Design model, and divides the entire internal network into the core layer, distribution layer and access layer. According to the requirement analysis of company, We determine the selection of network equipments, IP address, Virtual Local Area Network(VLAN) planning, routing protocol, and so on. For the security and stability of the network, the Hot Standby Routing Protocol(HSRP),Access Control List (ACL),Gigabit EtherChannel(GEC),the online version antivirus software and many other technology are used. The firewall will not only be deployed as the export of the corporate headquarters’internal network, but also as a Virtual Private Network(VPN) server. The corporate headquarters’firewall connect to the branch’s firewall through a secure IPSec VPN tunnel, allowing the staff who is going on the business trip to use a dial-up software and connect to company’s network. That realize the secure data connection.Besides, in the summary, the advantage and disadvantage of this system are analyzed. The direction of future improvement are also involved.
