In the network design of the information platform adopts traditional structured hierarchical design, dividing the whole enterprise network into core layer, convergence layer and access layer, selecting type and designing separately for the equipment.Select the network topological structure of mixed type and the structure which the inner and outer are isolated, by linking router, firewall, intrusion detective system, layer exchanger, server, workstation and other equipments, to frame the tree type network. Fiber to department and thousands of terabytes to every user have come true. In operation, Using Cisco’s three layer exchanger realized that VLAN manages all the departments and workshops. In branches, employees use VPF to dial in corporate inner network. Using the server software of ISA series, the employees’network access time and rights, etc are controlled effectively. Configure E-mail server and FTP server to realize the internal resource sharing in the company. Using hot standy two-node cluster, the safe and efficient operation of the server is effectively ensured. Adopt three-layer dimensional protection, which is a firewall, an intrusion detective system and a setting anti-virus server, to effectively protect the safety of corporate network. By wiring of main distributing strand, workspace sub-system and level sub-system finished the whole company’s network generic cabling system and set up the corporate network information platform.
