Abstract

The invention provides a multicast transmission method of network coding in an SDN network. An Openvswitch switch has an OpenFlow protocol supporting the network coding, and the Openvswitch switch is a switch that supports the OpenFlow protocol and can perform coding and decoding. The core technology, the OpenFlow protocol, of the SDN network is to separate a data layer and a control layer of a network device, the control layer provides service implementation and logic control, and the data layer executes data forwarding so as to realize flexible control and intelligent management of the network, and the network is convenient to expand. The network coding is a major breakthrough in the processing and transmission of information in the network, it allows an intermediate node of the network to perform coding processing on transmitted information and to perform decoding and restoration on a receiving node, thereby improving the network throughput, and the reliability and security of data transmission. By adoption of the multicast transmission method provided by the invention, the network coding is effectively applied to the SDN network, the problem that the network coding application cannot be organically combined with the SDN network in the prior art is overcome, and the advantages of the both are combined, thereby having an important research value on the network development in the future.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a network coded multicast propagation method in an SDN network. Background technique [0002] SDN is a new type of network architecture. Its core technology, the OpenFlow protocol, separates the data and control layers of network equipment. The control layer provides business implementation and logic control, and the data layer performs data forwarding, thereby realizing flexible control and intelligence of the network. Management, easy to expand. [0003] Network coding is a major breakthrough in the processing and transmission of information in the network. It allows the intermediate nodes of the network to encode the transmitted information, and decode and restore it at the receiving node, which improves the network throughput, reliability and security of data transmission. sex. [0004] If the network coding is applied to the SDN network and combines the advantage...
