The aggregation device for secure operation management establishes a dedicated remote operation network with the core layer via VPN through 4G/Internet/leased lines. The aggregation device is the source for initiating remote IP operations, providing users with remote IP operation methods and tools such as Web, Telnet, SSH, and RDP within the dedicated secure operation network. It simultaneously supports operations on the non-IP ports of one host device and one network device. Supporting 4G and 4G VPDN, it allows users to more flexibly build their own dedicated remote operation networks. It features two gigabit RJ45 Ethernet ports, two USB ports, two HDMI ports, one RS232 serial port, one OTG port, and one RJ45 console serial port. It supports user data analysis, application identification, and behavior auditing. Online user management, online user count analysis, internet access details management, network repair management, log management, and wireless roaming management can automatically provide operation reports, supporting unified operation and maintenance management functions.
