Метод выбора конфигурации распределенной платформы управления высокой готовности для транспортных программно-конфигурируемых сетей

Abstract

В работе рассматривается задача выбора конфигурации распределенной платформы управления (РПУ) с высокой степенью готовности для транспортных программно-конфигурируемых (ПКС) сетей. Для обеспечения устойчивости РПУ к единичным отказам контроллеров в рамках данной проблемы затрагиваются следующие аспекты: выбор размещения контроллеров РПУ в узлах транспортной ПКС сети, выбор основных и резервных контроллеров для каждого коммутатора сети с использованием наименьшего количества активных контроллеров распределенной платформы управления. В качестве критерия оптимизации размещения контроллеров рассматривается минимизация задержек на передачу управляющих сообщений между контроллером и коммутатором. В случае единичного отказа контроллера РПУ управление коммутаторами распределяется между исправными контроллерами таким образом, чтобы количество коммутаторов, управляемое одним контроллером, не превышало заданного максимального числа. Предлагается комплексный метод решения данной задачи, включающий в себя алгоритмы на графах, алгоритмы кластеризации и алгоритм решения задачи булевого линейного программирования, позволяющий выбрать размещение контроллеров РПУ в сети и конфигурацию основного и резервного контроллера для каждого коммутатора сети. Предложенный метод реализован в виде программного средства. Проведено экспериментальное исследование разработанного метода на топологиях реальных транспортных сетей. The method of choosing a configuration of a high availability distributed control platform (HA DCP) for transport software-defined networks is considered. To provide fault tolerance to single controller failures the following aspects are affected in this problem: the choice of the controller instance location in the nodes of the transport SDN, the choosing of the primary and backup controllers for each switch, determining the optimal number of active controllers for distributed control platform. The minimization of delays in the transmission of control messages between the controller and the switch is a criterion for optimizing the controller placement. In the case of a single controller failure, the management of the switches is distributed among the active backup controllers. A complex method for solving this problem is proposed, including algorithms on graphs, clustering algorithms, and an algorithm for solving the Boolean linear programming problem, which allows selecting the location of the controllers in the network and the configuration of the primary and backup controller for each switch. The proposed method is implemented as a software tool. An experimental investigation of the developed method on the topologies of real transport networks is carried out.
