| With the rapid development of China’s economy and Internet technology,the informationzation of government departments is also deepening,and the requirements for the development of information technology by human resources and social security services department are becoming more and more urgent.The construction of the exclusive network of the human society business is important for its operation,service quality and long-term development.The full use of the network is directly reflected in the improved office efficiency,streamlined dealing process,and reduced work errors.Palying a role as the main carrier of mass business data,the exclusive network promises the effcient internal management,quick external sharing and the daily business operation of governments,such as social security,employment services,wages and benefit.However,with the increase of network intrusion events such as website hacking and ransomware,network security has become a bottleneck restrcting the construction of information technology in government departments.The data of human society is related to the vital interests of the general public,so a secure network system is tremendously important.The main aim of this paper is to explore how to design and implement the private network of human society department.Firstly,this paper summarized and stated the background and current status of researches in private business network from both the domestic and abroad opinions.Second,in-depth analysis of the needs of the private network construction and the refined construction plans and principles focusing on the design and implementation of the network are donstrated in this paper.The design and implementation start from considerign the network architecture according to the top-down design idea which obeys the logical topology.The introduction and illusion of address allocation,VLAN division,device interconnection,port usage are furtherly explained in between.The deployment plan of hardware firewalls,switches and other core devices is also get invloved.Thirdly,this paper tried to figure out the hidden dangers in the process of network construction,and summarized three prominent hidden dangers,namely,unhealable faults,unreliability and unsafely.Fourth,this paper proposes solutions to the hidden dangers above-mentioned,which can effectively realize the self-healing of the network and ensure the reliability and security of the network.Fifth,simulation tests were conducted to achieve the desired results of network plan.Building a secure business network requires not only the good and flexible use of advanced technologies,integration of existing resources,but also the continuous improvement of the network environment,strengthened daily maintenance,and close attention to network security.The design and implementation of this project meets the needs of users,and plays an important role in the internal operations,management and scheduling of the department.At present,the network has been put into use and is running stably. |
