Home gateway

Abstract

The embodiment of the invention discloses a home gateway. The home gateway comprises a central processor, a virtual private network (VPN) module, a QoS module, a firewall function module, a log audit module and a network management module, wherein the central processor is used to communicate with each module and process the signals between the modules; the VPN module is used to adopt the standard IPSec protocol to set up a tunnel with another VPN gateway device supporting the standard IPSec protocol; the QoS module is used to realize the control function of the bandwidth flow, control the flow converted by a UTM physical interface and set up bandwidth policies to set the bandwidth limit and priority level of data messages; the firewall function module is used to identify and match the data messages from the angles of region, VLAN, address, user, connection and time and perform deep content inspection and filtration to various application layer protocols; the log audit module is used to provide a perfect log and alarm service function; and the network management module is used to realize network visualization and real-time monitoring and analysis. By implementing the invention, the deployment, management and maintenance costs of devices can be greatly reduced.
