Abstract

The present invention provides a method and system for dynamically adjusting the topological structure of the underlying network spanning tree, wherein the method includes the following steps: periodically obtaining the load information of the underlying network switch; calculating the total weight of the current underlying network spanning tree in real time according to the load information; The minimum spanning tree is determined according to the total weight of the spanning tree of the current underlying network, and the topology structure of the spanning tree of the network is dynamically adjusted. The system includes information collection module and STP module. The present invention centrally manages and controls the underlying network switch through the SDN controller, adopts the OpenFlow protocol module as the management interface, and completes the topology identification function of the underlying network and the construction of the spanning tree structure on the controller. During the operation of the network, the controller obtains the forwarding traffic information of the underlying network switch in real time, so that some spare link bandwidth can be used, and then the network can realize the function of dynamic load balancing, preventing loops in the forwarding of layer 2 network services and forming network storms Case.

Description

technical field [0001] The present invention relates to the technical field of computer networks, in particular to a method and a system for dynamically adjusting the topological structure of the underlying network spanning tree based on the OpenFlow protocol. Background technique [0002] In traditional Layer 2 networks, topology identification and acyclic processing mainly rely on Spanning Tree Protocol (STP for short) and rapid spanning tree protocol (RSTP for short), but neither STP nor RSTP There are many defects: when the network scale is relatively large, it will lead to a long convergence time; the mechanism of the STP protocol is to block the port of the redundant link to avoid network loops. When the link is blocked, it will not carry any traffic. This results in a great waste of bandwidth, and during the entire network communication process, the topology cannot be changed due to the slow convergence problem. And some subsequent protocols were proposed to solve th...
