Embodiment Construction

[0049] Embodiments of the present invention provide a method for perceiving network security equipment, network security equipment and a controller. The method, network security equipment and controller are applied to a software-defined network (SDN, Software Defined Network), which solves the problem that cannot be realized by the prior art. The controller senses a problem with the network security device.

[0050] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0051] An embodiment of the present invention provides a method for sensing network security devices, such as figure 1 As shown, the method can be performed by a network security device, and the method includes:

[0052] Step 101: the network security device receives a Link Layer Discovery Protocol (LLDP) packet.

[0053] Wherein, the LLDP packet is sent by the OpenFlow switch to the network security device.

[0054] Step 102: The network sec...

Abstract

The invention discloses a method for sensing network security equipment, the network security equipment, and a controller, and the problem that in the prior art, the controller cannot sense the network security equipment is solved. The method includes: the network security equipment receives a link layer discovery protocol (LLDP) message; and the network security equipment adds equipment information of the network security equipment to the LLDP message, and sends the LLDP message with the added equipment information of the network security equipment to the controller so that the controller senses the network security equipment via the equipment information of the network security equipment in the LLDP message.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for sensing network security equipment, network security equipment and a controller. Background technique [0002] Software Defined Network (SDN, SoftwareDefinedNetwork) is to separate the control function of the switch or router in the original network and hand it over to the controller (Controller). The original switch or router is only responsible for the standardized data forwarding function. , thus realizing the separation of the control plane and the data plane. The user can program it on the controller to realize the network control function that the user needs. [0003] OpenFlow technology is currently the most common implementation of SDN networks. OpenFlow in the narrow sense refers to the OpenFlow protocol or the OpenFlow network architecture, and OpenFlow in the broad sense refers to the OpenFlow standard. [0004] In the OpenFlow network arc...
