SDN architecture-based communication network multidimensional resource regulation method and system

Abstract

The invention relates to network communication technologies, and discloses an SDN architecture-based communication network multidimensional resource regulation method. The method specifically comprises the following steps: step 1, constructing a device model for a device to be regulated in a network; step 2, after an SDN controller completes network topology sensing to all devices, obtaining current situation data; step 3, by utilizing the SDN controller, comparing a previous moment historical value according to each dimensional value of node performance, calculating modification factors of each dimension of the node, combining dimension weight values of two situations, namely preset transmission speed precedence and transmission reliability precedence, utilizing a shortest path algorithm to obtain an optimal route, and sending the optimal route to the network device; and step 4, by utilizing an upper-layer application program, according to service features, making feature marks on service data, and by matching with preset route information of the network device, performing message forwarding. The method provided by the invention greatly balances network loads.

Description

technical field [0001] The present invention relates to the technical field of network resource control, in particular to a method and system for multi-dimensional resource control of a communication network based on an SDN architecture. Background technique [0002] With the rapid development of new networks such as mobile Internet and cloud computing networks, business types are becoming more and more diverse, the amount of transmitted data is increasing explosively, and requirements are becoming more and more complex. The demand for rational use of network resources and efficient transmission of services based on their respective characteristics is becoming more and more urgent. Traditional IP networks are difficult to meet the requirements. The industry has proposed a software-defined network (SDN) network architecture to separate data forwarding from the control plane. Centralized management of the network, global control of network resources, and use of flow tables to ...

The demand for rational use of network resources and efficient transmission of services based on their respective characteristics is becoming more and more urgent. Traditional IP networks are difficult to meet the requirements. The industry has proposed a software-defined network (SDN) network architecture to separate data forwarding from the control plane. Centralized management of the network, global control of network resources, and use of flow tables to control service forwarding, but in the actual implementation process, it is difficult to achieve the desired effect, and there are deficiencies and deficiencies. The main shortcomings are as follows:

[0003] (1) The separation of control and forwarding adopted by the SDN network, and the centralized control method. In an ideal state, each type of business must first a
