Abstract

The invention relates to a dynamic load balancing method based on an SDN. The method comprises the following steps: finding an optimal path from a source host to a destination host; and setting a dynamic load balancing threshold for a system, when detecting that a load balancing parameter exceeds the dynamic load balancing threshold, triggering a parallel dynamic scheduling strategy to perform dynamic adjustment on the load, and scheduling partial data streams on a node with a smaller load, otherwise, transmitting the entire data streams in the optimal path. The dynamic load balancing method based on the SDN provided by the invention can improve the stability of the whole system and the optimization of route selection, and improve the utilization ratio of a whole link.

Description

technical field [0001] The invention relates to the field of network technology, in particular to an SDN-based dynamic load balancing method. Background technique [0002] SDN is a technology that originated from the research project of the Stanford University laboratory in the United States in 2006; in 2007, Nick McKeown published the article "OpenFlow: Enabling Innovation in CampusNetworks" at the SIGCOMM conference, and first proposed the experimental innovation of using the OpenFlow protocol for campus networks; At the beginning of 2011, Google, Facebook, Yahoo and other industry heavyweights jointly established the ONF (Open Networking Foundation, Open Network Foundation), and formally proposed the concept of software-defined networking; in 2014, Facebook launched the Wedge SDN switch, ON. Lab released the open source SDN operating system ONOS, and Cisco joined the Open Computing Project OCP; in 2015, VMware NSX was deployed in more than 1,000 companies, and the revenue...
