Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The openflow-based data center flow control method of the present invention organically combines openflow switches and flow optimization technology, improves the utilization rate of network bandwidth resources and the accuracy and reliability of network centralized management, and flexibly allocates traffic in the network Load to adapt to changes in network traffic, effectively improving the utilization and reliability of the network, specifically including the following steps,

[0036] Step (a) Construct the network topology

[0037] The network controller controls the openflow switch to run the topology discovery protocol, collects all network node and link information, and constructs the network topology. The method of constructing the network topology is:

[0038] (a1) Each openflow switch periodically sends probe data packets to all ports in the network, a...

Abstract

The invention discloses a data center flow control method and a data center flow control system based on openflow. Openflow switchboards are controlled to operate a topology discovery protocol through a network controller, so tha information of all network nodes and links is collected and a network topology value is calculated; and the network controller periodically carries out end-to-end flow analysis on flows, calculates optimized paths of all the flows and transmits the optimized paths to each openflow switchboard, monitors the states of all the network links in real time, and maintains or downloads the optimized paths of the new flows to each openflow switchboard, so that the use rate of network bandwidth resources and the accuracy and the reliability of network concentrated management can be improved, the variation of the network flow can be fitted by sensitively regulating a flow load in a network, and the use rate and the reliability of the network can be effectively improved. The data center flow control method and the data center flow control system based on the openflow has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an openflow-based data center flow control method and system. Background technique [0002] With the development of Internet applications and cloud computing, data centers that support Internet and cloud computing services have become the core competitiveness of enterprise business. At present, the development of network technology in data centers is becoming more and more virtualized, scalable, and centralized control. , The virtualization architecture design, scalable design and centralized management of the data center bring great challenges to the current data center technology. For this reason, software-defined networking (SDN) has become the network technology of choice for next-generation data centers. The new openflow (a new network switching model proposed by network reformers) proposed by Stanford University in the United States is the most typical softwa...
