中小企业网络架构优化研究OA

With the rapid development of information technology,the network architecture of small and medium sized enterprises plays an increasingly important role in enterprise operation.The contradiction between Internet security,convenience and construction cost has become the core concern.In this paper,the original three-layer switch is used to dial up the network,and then the network architecture of the home wireless router is connected from each port.The wireless AP panel is used to replace the original office network panel.Each AP panel is connected to the PoE aggregation switch and connected to the AC controller to realize the unification of the wireless and wired networks of the enterprise.The original dial-up three-layer switch is configured as a DHCP server,and VLAN is divided into PoE aggregation switches of various departments.A new firewall is added to the enterprise network export end,which also acts as a static router.This network optimization project has built a wired and wireless network at a low cost,taking into account security and ease of use.The AC controller,the three-layer switch and the firewall used are all medium-priced enterprise-level products on the market.The memory usage of the three devices is basically controlled at about 50%in actual work,and the CPU performance utilization rate is maintained at about 15%,which not only makes full use of the device performance and achieves overall load balancing,but also reserves a certain amount of redundancy for the possible expansion of the enterprise network in the future.
