Abstract

The invention provides a distributed virtual firewall device and a method. The device comprises a firewall controller and a firewall module, wherein the firewall controller is arranged on a cloud calculation management node and sends configuration information and firewall strategy information to the firewall module, the firewall module is arranged on a host node, and filtering detection on network flow in a virtual switch vSwitch is carried out according to the received configuration information and the firewall strategy information. Through the distributed virtual firewall device and the method, filtering detection on the network flow in the virtual switch vSwitch is carried out through the firewall module according to the received configuration information and the firewall strategy information, performance bottleneck in networking can be avoided, and the device further has advantages of abundant configuration strategy and flexible performance.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a distributed virtual firewall device and method. Background technique [0002] In the traditional cloud network security solution, the east-west network traffic control of the virtual network can be divided into two solutions based on the virtual switch configuration access control list (Access Control List, ACL) control strategy and running virtual firewall software in the virtual machine. Program. The implementation of the ACL control strategy based on the virtual switch has the disadvantages that the configurable strategy is not rich enough, flexible and the control strategy cannot identify the data of the business layer; while the firewall software based on the virtual machine has strict networking requirements, complex configuration strategies and problems. There are disadvantages such as performance bottlenecks. Contents of the invention [0003] The technica...
