| Summary: | One of the actively developing technologies in telecommunications is Software-Defined Networking (SDN). Its usage will automate the management and administration of network equipment, greatly accelerates the organization of new services for users, and will give other advantages. A new control element, the "brain" of the SDN, is a controller that performs the functions of controlling physical devices (switches) and at the same time interacts with the application layer. One of the most important characteristics of any communication networks is reliability, and the reliability requirements are increasing with the expansion and intensification of usage of information and communication systems. This paper discusses main aspects of reliability for SDN. As the controller is a key element of the centralized network control, its failure or loss of connection with switches leads to the inability of the normal functioning of the network. Therefore, it is important to ensure the high reliability of the controller and its connections with network elements. On the example of a typical SDN network, several options for placing and linking controllers and for redundancy of connections with them are analyzed. The results of calculations show the need for redundancy of controllers and their connections with all nodes in the network. |
