Embodiment Construction

[0037] In order to solve the problem of the prior art: In the SDN architecture, existing Ethernet broadcast processing mechanism resources are over-selling, and there are many safety hazards, and the SDN controller is loaded, and it is easy to cause broadcast storms; the present invention provides a The processing method, apparatus, controller, and switch of broadcast packets, will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to explain the invention and is not limited.

[0038] The first embodiment of the present invention provides a method of processing a broadcast message, and the process of which is figure 1 As shown, steps S102 to S106 are included:

[0039] S102, the controller divides the switches and user hosts present on the network to different virtual networks based on network configuration information.

[0040] S104, the controlle...

Abstract

The invention discloses a broadcast message processing method, device, controller and switch, wherein the method includes: the controller divides switches and user hosts existing on the network into different virtual networks according to network configuration information; The router sets up a broadcast tree for each virtual network, where the root node of the broadcast tree is a switch, the branch nodes are multiple switches, and the leaf nodes are the user host and / or the virtual network where the broadcast tree belongs according to the network configuration information. The switch port of the network; the controller generates the broadcast flow table and the broadcast group table of the virtual network according to the broadcast tree, and sends the broadcast flow table and the broadcast group table to each switch on the broadcast tree, so that each switch can The group table forwards the received broadcast message. By using the present invention, the problem that the load of the controller in the SDN architecture of the prior art is relatively large and broadcast storms are easily caused is solved.

Description

Technical field [0001] The present invention relates to the field of communication, and in particular, to a processing method, apparatus, controller, and switch for broadcast messages. Background technique [0002] Today's network technology day and new months, traditional Internet based on TCP / IP (Transmission Control Protocol / Internet Connection Agreement, Transmission Control Protocol / Internet Protocol) is increasing in many aspects of service quality experience, business deployment, business adaptation, etc. The more questions and challenges. SDN (Software Definition Network, Software Defined Network) proposes a user-customized controller that implements the converter device, providing the user with the flexible control of the network behavior, and began to become an important technical direction of the next generation of Internet development. [0003] A basic SDN network includes two main control entities of the network controller and switches. The SDN network focuses ...
