On the Trade-Off between Control Plane Load and Data Plane Efficiency in Software Defined Networks
نویسندگان
چکیده
Software Defined Networking (SDN) is a new emerging network architecture, which allows, among other things, an efficient convergence between circuit switching and packet switching. However, this convergence imposes a trade-off between control plane load and data plane efficiency: while the SDN controller needs to establish one or more paths (circuits) that can deliver the required bandwidth with minimum data plane cost, this is made difficult by the load imposed on the control plane due to setup and OAM demands. The present paper defines and studies this trade-off from both theoretical and practical perspectives.

A New Reliable Controller Placement Model for Software-Defined WANs
Software-Defined Network (SDNs) is a decoupled architecture that enables administrators to build a customizable and manageable network. Although the decoupled control plane provides flexible management and facilitates the task of operating the network, it is the vulnerable point of failure in SDN. To achieve a reliable control plane, multiple controller are often needed so that each switch must...

متن کاملPre-Cracked Concrete Shear Strengthened with External CFRP Strips
In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...
