Abstract

The invention relates to the technical field of communication, in particular to a data packet processing method, a switch, a controller and a medium. The method comprises the steps that a reporting rule is received from the controller, wherein the reporting rule is used for instructing the switch to report a data packet to the controller; the data packet is received; whether the data packet belongs to reported data flow or not is determined according to the reporting rule; and if the data packet does not belong to the reported data flow, the data packet is reported to the controller, or otherwise, the data packet is not reported to the controller. According to the method, the data flow to which the data packet belongs can be distinguished, and speed limitation can be carried out accordingto flow granularity in a Packet IN scene, so that the unfairness between the large flow and the small flow is avoided; the controller or network condition can be fully considered, and the number of Packet IN messages is dynamically adjusted, so that the crash of the controller is avoided; and the Packet IN scheme can be applied to a data center scene, so that the problem that the active pushing scheme is difficult to apply to a large-scale data center is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for processing data packets, a switch, a controller and a medium. Background technique [0002] OpenFlow (OpenFlow) was first proposed by researchers such as Professor Nick McKeown of Stanford University in the paper "OpenFlow: Enabling Innovation in Campus Networks" published in April 2008, and specifically proposed an architecture that separates control and forwarding, and the control logic It is derived from network equipment for researchers to program it arbitrarily, so as to realize new network protocols and topology structures without changing the network equipment itself. The software-defined network (Software Defined Network, SDN) does not run any protocol between the network devices, the forwarding table of the network device is generated by the configuration of the controller, and the controller and the network device communicate with each other through t...
