Computer system and method for dynamically adapting a software-defined network A computer system for dynamically adapting a software-defined network is suggested. The computer system comprises a plurality of virtual domains, each virtual domain comprising a network controller to which a back-up network controller is assigned, wherein the network controller is adapted to manage a plurality of switches being assigned to the virtual domain, wherein the software-defined network is partitioned into the plurality of virtual domains, and a root controller, wherein the root controller is adapted to manage the software-defined network by dynamically adding and/or removing virtual domains based on a threshold of the software-defined network, wherein a back-up root controller is assigned to the root controller. Further, a method for dynamically adapting a software-defined network is suggested. The suggested computer system provides the advantage of a dynamical adaptation of the software-defined network and at the same time, due to the back-up controllers, an improved fault-tolerance.
A computer system for dynamically adapting a software-defined network, the computer system comprising:
A method for dynamically adapting a software-defined network, wherein the software-defined network is partitioned into a plurality of virtual domains, each virtual domain of the plurality of virtual domains comprising a network controller to which a backup network controller is assigned, wherein the software-defined network comprises a root controller, wherein a back-up root controller is assigned to the root controller, wherein the back-up root controller is configured to monitor the root controller and to determine a fault of the root controller, and wherein the back-up root controller is configured to take over management of the software-defined network, the method comprising:
In a non-transitory computer-readable storage medium that stores instructions executable by at least one computer to dynamically adapt a software-defined network, wherein the software-defined network is partitioned into a plurality of virtual domains, each virtual domain of the plurality of virtual domains comprising a network controller to which a backup network controller is assigned, wherein the software-defined network comprises a root controller, wherein a back-up root controller is assigned to the root controller, wherein the back-up root controller is configured to monitor the root controller and to determine a fault of the root controller, and wherein the back-up root controller is configured to take over management of the software-defined network, the instructions comprising:
