The Controller Placement Problem (CPP), in Software Defined Networks (SDNs), deals with
placing an optimal number of controllers. The CPP aims to maximize the network throughput …

Controller placement problem (CPP) is a key issue for Software-Defined Networking (SDN)
with distributed controller architectures. This problem aims to determine a suitable number of …

In Software Defined Networks (SDN), controllers should ideally be optimally placed to
preserve the minimal response time between the controllers and the forwarding nodes in the …

Abstract Software-Defined Networks (SDNs) are characterized by dividing a network
architecture in a data plane (ie, any packet-relaying nodes like switches or routers) and a …

Controller placement is a key problem in software defined networks (SDNs). Previously, the
solution to this problem only focused on propagation latency but ignored the load of …

Software 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 …

Software Defined Network (SDN) is a new type of network structure, which decouples the
data plane from the control planes, and improves network flexibility. However, this …

A distinctive feature of software‐defined networking (SDN) is a logically centralized control
plane realized using multiple physical controllers. The placement of the controllers, the so …

Software-Defined Networking (SDN) is a network paradigm introduced to overcome the
inherent challenges of traditional networks. Its architecture is either deployed with a single …

Abstract Software Defined Networking (SDN) decouples control and data planes. The
separation arises a problem known as the controller placement, ie, how many and where …
