Abstract

The invention provides a construction method of a gateway firewall combining software and hardware and a network protection method thereof. The construction method includes: obtaining a user's gateway firewall creation request; determining a gateway firewall node according to the gateway firewall creation request; installing a smart gateway on the gateway firewall node network card, and enable the gateway firewall offload function of the smart network card; decompose the gateway firewall to be created into the firewall of the data link layer and the network layer, and the firewall of the transport layer and the network layer above; uninstall the firewall of the data link layer and the network layer To the intelligent network card, and create a firewall at the transport layer and above in the user space, and generate a gateway firewall that combines software and hardware. Based on the software gateway firewall, the present invention provides a high-performance and stable software and hardware combination gateway firewall service for the cloud environment by combining the software gateway firewall with the unloading technology of the smart network card. cost.

Description

technical field [0001] The invention relates to the technical field of data migration, in particular to a construction method of a gateway firewall combining software and hardware and a network protection method thereof. Background technique [0002] With the rapid development of network, virtualization, and storage technologies, cloud computing has become one of the most interesting network technologies. It can be said that network technology has entered the era of cloud computing. They have built their own data centers to support and develop their own businesses. [0003] With the development of cloud computing technology, the demand for high-performance gateway firewalls for cloud hosts in the cloud environment is also increasing. Whether it is a public cloud or a private cloud, the performance requirements of the gateway firewall are getting higher and higher. At present, most cloud environments use software gateway firewall solutions based on kernel + user mode softwar...
