Planning and deployment of multi branch network application in manufacturing industry
Abstract
With the development of enterprise, network scale also in increasing, with the expansion of business, enterprise in other cities established branches, how to realize the security communication branches and headquarters, the establishment of multi branch enterprise network is the main content of this paper.
This paper is the analysis and design of the construction of multi branch network in manufacturing industry. Through network construction, realizes the connection of various departments within the enterprise network, the resource sharing service, enterprise user can be connected to the Internet, the network of branches and headquarters can secure interconnection, the realization of network security control. This paper mainly analyzed the background and demand of enterprise network, the research of the enterprise network, on level of technology of the design of network structure analysis design network topology, IP address and VLAN information was pided in detail, with the selection of equipment for the network design, and discusses the key technology used in network design, mainly includes the VPN technology, address conversion technology, firewall technology, dynamic routing protocol technology, access control technology, spanning tree protocol, for equipment key configuration and train of thought to explain, to configuration commands are described.
The key point of this article is to use the VPN technology to realize the secure interconnection of branches, using the firewall and access control technology to enhance the security of the network, and control the data access. In this paper, the key technologies and configurations are simulated, and the technology verification is carried out.
