A survey and classification of controller placement problem in SDN
International Journal of Network Management, 2018SummarySoftware defined networking emerges as a promising paradigm shift that decouples the control plane from the data plane. It has the ability to centrally monitor and control the network through softwarization, ie, controller. Deploying a single controller is inefficient to handle large network traffic; thereby, making multiple controllers are a ...

Heuristic approaches for the reliable SDN controller placement problem
Transactions on Emerging Telecommunications Technologies, 2019AbstractSoftware‐defined networking (SDN) is one of the most used network architecture that divides the forwarding plane and control plane. The SDN centrally observes and regulates the network through a software control in the control plane, called as controller.

A Review of SDN-Based Controller Placement Problem
2020 2nd International Multidisciplinary Information Technology and Engineering Conference (IMITEC), 2020Software Defined Networks (SDN) is a novel computing paradigm that decouples the control plane from the data plane. Its introduction has brought about great and innovative changes in the way the computer network is designed, managed, and operated. Currently, SDN architecture can be deployed with a single centralized controller or multiple controllers ...

Virtualized control plane placement problem: Provisioning the control paths and architectures
2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017A fundamental problem to be resolved to achieve carrier grade functioning of an SDN network is the controller placement problem. The problem has been traditionally limited to optimally assigning switches to static physical controllers and placing those controllers over a network topology. However, virtualized controllers in place of physical ones could

On SDN Controllers Placement Problem in Wide Area Networks
2020Software Defined Networking (SDN) is a new paradigm where the forward plan is decoupled from the control plan. The controller is a central program that tells the switches and routers how to react to the incoming flows and different network changes. The placement of the controllers considering different metrics becomes a challenge in SDN WAN.

On the multi input pole placement control problem
Proceedings of the 36th IEEE Conference on Decision and Control, 2002Feedback control of linear systems is efficiently made by the use of state space tools. It is well known that the use of an observer in combination with a state feedback gain generates linear time invariant closed loop systems with predetermined dynamics obtained by specifying a set of desired closed loop poles.

The controller placement problem for software-defined networks
2016 2nd IEEE International Conference on Computer and Communications (ICCC), 2016With the popularization and spread of SDN, the size of SDN networks is increasing; the controller placement is a key problem in software defined networks (SDNs). In this paper, an optimized controller placement method is proposed, which takes into consideration the load of controllers, co-located deployment and propagation latency to determine the ...

Fuzzy Approach to Controller Placement Problem: Fuzzy Controller (FC)
2018 International Conference on Advances in Big Data, Computing and Data Communication Systems (icABCD), 2018Software Defined Networks provide separation of data and control plane and reduce management complexity of the entire network. The customized centralized controller that is flexible and programmable is responsible for dynamic and efficient network management.

Solving Multi-controller Placement Problem in Software Defined Network
2016 International Conference on Information Technology (ICIT), 2016The Software Defined Network (SDN), is the next generation Internet technology, which not only solve the ossification of the Internet, but also creates new innovations and simplify the network management. The key idea behind SDN is separation of control plane from data plane, as a result devices in the data plane becomes the forwarding device and ...

A robust topology control solution for the sink placement problem in WSNs
Journal of Network and Computer Applications, 2014Placing a certain number of sinks at appropriate locations in WSNs reduces the number of hops between a sensor and its sink resulting in less exchanged messages between nodes and consequently less energy consumption. Since finding the optimal number of the sinks to be added and their locations is an NP Hard problem, we propose in this paper, a ...
