Embodiment Construction

[0037] In order to solve the following problems in the prior art: in the SDN architecture, the existing Ethernet broadcast processing mechanism has large resource overhead, many security risks, and the SDN controller has a large load, and it is easy to cause a broadcast storm; the present invention provides a The method, device, controller, and switch for processing broadcast messages will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The first embodiment of the present invention provides a method for processing broadcast messages, the flow of the method is as follows figure 1 As shown, including steps S102 to S106:

[0039] S102. The controller divides switches and user hosts existing on the network into different virtual networks accordi...

Abstract

The invention discloses a broadcast message processing method, a broadcast message processing device, a controller and a switch. The broadcast message processing method comprises the steps that: the controller classifies switches and user hosts existing on a network into different virtual networks according to network configuration information; the controller sets a broadcast tree for each virtualnetwork,, wherein a root node of the broadcast trees is one of the switches, branch nodes are a plurality of the switches different from the switch, and leaf nodes are user hosts and/or switch portsof the virtual networks which are determined according to the network configuration information and in which the home broadcast trees locate; and the controller generates broadcast flow tables and broadcast group tables of the virtual networks according to the broadcast trees, and transmits the broadcast flow tables and the broadcast group tables to the switches on the broadcast trees, so that theswitches forward received broadcast messages according to the broadcast flow tables and the broadcast group tables. By adopting the broadcast message processing method, the broadcast message processing device, the controller and the switch, the problems that load of a controller in an SDN architecture in the prior art is large and prone to cause a broadcast storm.

Description

technical field [0001] The invention relates to the communication field, in particular to a broadcast message processing method, device, controller and switch. Background technique [0002] The network technology in today's world is changing with each passing day. The traditional Internet based on technologies such as TCP / IP (Transmission Control Protocol / Internet Protocol) is experiencing more and more problems in terms of service quality experience, business deployment, and business adaptation. more problems and challenges. SDN (Software Defined Network) proposes that a centralized controller realizes user customization of forwarding plane equipment, and provides users with programmable APIs to realize flexible control of network behavior, which has begun to become an important technical direction for the development of the next generation Internet. [0003] A basic SDN network includes two main control entities, the network controller and the switch. The SDN network con...
