Abstract

The invention discloses a software optical network controller deployment method and a storage medium, belongs to the technical field of networks, and is applied to two-layer SDN controller deployment.On the premise that the survivability requirement of a user for a control plane in a large-scale network (namely a network with more nodes and higher total degree) is met, the control redundancy is reduced as much as possible, and the deployment cost of a controller is reduced. According to the method, the maximum fault probability P provided by the user is obtained, then the controller combination meeting the condition is obtained through calculation, the dependence of each SDN switch node on the whole network is calculated accordingly, and finally the optimal controller deployment scheme isobtained.

Description

technical field [0001] The invention belongs to the cross-layer survivability design part of a control plane in a software-defined optical network, and specifically relates to a deployment method of a two-layer SDN controller that combines regional control and centralized control in the control plane. Background technique [0002] In recent years, with the rapid growth of user demand for high-traffic consumption Internet applications such as online video and voice calls, the optical network infrastructure, which bears the main traffic pressure in the network, is facing huge challenges: on the one hand, the network transmission capacity is required to change. On the other hand, it requires more real-time and flexible network management and control. [0003] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture proposed by the clean-slate research group of Stanford University in the United States, and it is a way to realize network v...
