Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] With the rapid expansion of the scale of the Internet, more and more data is concentrated in the data center for processing. When the data is relatively concentrated for transmission, the network traffic will increase instantly, causing link congestion and even network paralysis. This will degrade the service performance of the data center and affect the daily operation of the business.

[0032] In recent years, there have been many studies on link load balancing in the SDN environment. For example, the literature proposes the K-Dijkstra algorithm, which uses the controller to evaluate the network status globally, and then combines the K-Dijkstra algorithm to solve the shortest p...

Abstract

The invention provides a link load balancing method based on a software defined network, and the method comprises the following steps: S1, issuing an LLDP message through a Ryu controller to obtain network link information, and generating a network topological graph by utilizing the obtained network link information; S2, enabling a network awareness application to use a directed graph data structure of the Networkx to store the topological information, and calculating a short path on the basis of the topological information by using a shortest_simple_paths function provided by the Networkx. The invention has the beneficial effects that the controller updates and calculates the nodes in the transmission process in real time based on the global checking capability of the SDN on the network architecture, selects the optimal path and performs data transmission. Simulation is carried out through a Mininet tool, shortest path forwarding is achieved through Network x, and the result shows that the SDN-HLLB can improve the data transmission rate, achieve network link load balancing and meet the requirement of a user for the transmission rate in a complex environment.
