Abstract

The invention discloses a method and equipment for real-time and dynamic flow control through the connection between a controller and network equipment. The method for dynamic flow control includes the steps of: creating at least one flow entry to control the flow of a network device; and transmitting the created at least one flow entry to the network device to control the flow of the network device, wherein the at least one flow entry includes a flow threshold or Information on target values ​​to control flow. Therefore, the communication load between the network device and the controller and the system load of the network device can be reduced. Furthermore, real-time services can be provided through dynamic flow control.

Description

Technical field [0001] The present invention relates to a software-defined network technology, and more specifically to a method and equipment for dynamically controlling flow in real time through the interoperation between a controller and a network device. Background technique [0002] Software-defined networking (SDN) is a user-oriented network in which users have control over basic network devices such as routers or switches, and independent software controllers control the flow of traffic. [0003] In the SDN environment, the flow table including the identification information of the traffic flow and the information of the processing flow is managed. When the actual user traffic is generated, the flow entry corresponding to the generated flow is identified using the flow table, and the packet processing mode of the generated flow is determined based on the identified flow entry. [0004] Data packet processing methods in the SDN environment can include traffic forwarding, traff...
