Problems solved by technology

[0003] 1. Through the solution of deploying openstack network nodes, this solution completes the security control of traffic through the implementation of software firewall, but because it is a software method, it cannot support large-scale network deployment, and the forwarding capability is limited when the network traffic is large;
[0004] 2. Through the solution of deploying physical security devices, this solution implements security traffic control by deploying a security firewall outside the gateway and forwarding through the VXLAN (Virtual Extensible Local Area Network, Virtual Extended Local Area Network) network. However, due to the traditional security firewall equipment VXLAN forwarding is not supported, so this solution cannot be used for deployment

Abstract

The embodiment of the invention discloses a security resource management and control method and device in an SDN (Software Defined Network). The method comprises the following steps: interconnecting agateway with firewalls connected in series outside the gateway in a VLAN (Virtual Local Area Network) manner; forwarding the flow data sent to the external network by the virtual machine from the gateway to the firewall in the VLAN mode; and performing security control on the flow data through the firewall, and forwarding the flow data to an external network. The security management and control of the network flow of the virtual machine are realized.

Description

technical field [0001] Embodiments of the present invention relate to network security control technologies, and in particular to a method and device for managing and controlling security resources in an SDN network. Background technique [0002] SDN (Software Defined Networks, software-defined network) is a new type of network architecture, which realizes flexible control of network traffic by separating the control plane and data plane. In order to implement security control of external network traffic, the SDN controller usually needs to have a firewall function. How to effectively manage firewall resources and deploy services through SDN controllers has become an important research direction in SDN networks. Generally, the SDN controller manages security resources as follows: [0003] 1. Through the solution of deploying openstack network nodes, this solution completes the security control of traffic through the implementation of software firewall, but because it is a ...
