Software definition networking method of state sensing

Abstract

The invention relates to a software definition networking method of state sensing. The software definition networking method comprises steps of: step 1: inputting a data level network parameter, an adjacent matrix AN*N, an end-to-end flow request matrix gammaN*N, link capacity Ce, a maximum link utilization rate alpha and a low request transmission rate lower limit beta; step 2: calculating a data level network path set, and solving all path sets P between two points in a directed connected graph according to a depth-first traversal method of the graph; step 3: calculating a link state matrix Ukpe; step 4: establishing a multi-source multi-sink maximum flow model based on a path hop count; and step 5: solving a model constructed in the step 4 by use of the CPLEX, and outputting the end-to-end maximum flow based on energy efficiency priority. According to the invention, the maximum flow solution based on a path is adopted; in order to improving energy efficiency of a data level network, the path hop count is used as a restriction condition, and a flow transmission path with lowest bit energy consumption is established for an end-to-end request every time, so an objective of division of high energy efficiency data level network is met.

Description

technical field [0001] The invention relates to the key technical field of software-defined optical fiber network, in particular to a state-aware software-defined networking method. Background technique [0002] With the large-scale deployment of virtualization and cloud computing, various broadband data services are developing rapidly, the number of users, bandwidth requirements, and network traffic are constantly increasing, and the energy consumption of network equipment is also increasing steadily. key issues of the network. When the utilization rate of the system server and network is at 15% and the energy and load of the server have a good ratio, the energy consumption of network communication is close to 50% of the total energy consumption. It can be seen that saving the energy consumption of network communication is of great significance to the network system. [0003] At present, there are many studies on network energy efficiency strategies, including traditional...
