NatShell NE-80 series multi-functional flow control gateway relies on the most advanced packet processing technology in the current computer field to develop a powerful traffic analysis engine. It adopts deep packet (DPI) and deep data flow processing technology (DFI) to make the most accurate identification of the data messages flowing through. The whole system mainly consists of four major parts: application feature library, application identification system, application management system, application routing, and real-time monitoring and management of all application data flowing through it through five major human-machine interactive management functions: system management, network management, policy management, monitoring statistics, and panel management. Multiple deployment methods can adapt to various complex network environments and meet the networking needs of different users; multiple Internet access methods such as PPPOE, DHCP, and dial-free host can provide the most reasonable Internet access for customer groups; flexible bandwidth management methods such as intelligent QOS and policy routing provide flexible and convenient means for users to regulate network bandwidth resources; rich charting and statistical functions allow administrators to The rich chart statistics function allows administrators to have a good understanding of users' Internet behavior and the traffic distribution of each application; the HTTPS web interface in full Chinese culture allows administrators to manage and configure the system safely anytime and anywhere; the whole system realizes traffic control objectives and network security protection in various networks, especially in complex networks, through application routing, application shunting, application priority, DNS control, security management and other functions. It is the preferred routing product for ISP operators, communities, enterprises, universities, hotels and other Internet access sites!
