The introduction of distributed control plane has improved the scalability and reliability of software defined networking (SDN), and multi-controller could divide the entire network into several subdomains. However, dynamic traffic could cause uneven load distribution among individual controllers. Furthermore, the static configuration between switch and controller exacerbates this imbalance. Real-time migration of switches from controllers that are overloaded to those that are underutilized could be a solution to deal with the unbalanced distribution of traffic. Therefore, such migration must be performed with a well-defined strategy to fully utilize the available resource of controllers. In this paper, we propose Distribution Decision Strategy (DDS) based on switch migration in the multi-domain SDN network. Firstly, we collect network information and construct distributed migration decision domains based on the load condition of controllers. Then, we choose the migrating switches according to the selection probability, and the target controller is determined by optimizing three network costs, including data collection, switch migration and controller state synchronization. Finally, we set the migrating countdown to ensure the ordered switch migration. Results are demonstrated by several numerical simulations.

A DDS/SDN Based Communication System for Efficient Support of Dynamic Distributed Real-Time Applications. Abstract: Many distributed real-time applications have ...
Many distributed real-time applications have dynamic requirements regarding communication delay and bandwidth. The Data Distribution Service (DDS) middleware is a key enabling technology used to support such applications. Indeed, the publish/subscribe distribution model of DDS with the ability to assign dynamic QoS (Quality of Service) parameters to DDS distribution services is able to take into account changes in the exchanged data flows and in the required QoS. This variability is taken into account at the middleware level to adjust some of DDS QoS mechanisms but is rarely propagated to the network layer to provide dynamic network communication services that fit the varying DDS distribution service needs. Usually, an over provisioned network is used, leading to network resource wastage. This paper addresses this issue and proposes a communication architecture that combines DDS with a new emerging class of communication networks named Software Defined Networks (SDN) to support efficiently dynamic distributed applications. SDN bring flexibility to the network and enable the provision of on-demand dynamic network communication services.
