Abstract SDN (Software-Defined Networking) is a new technology that separates data and
control planes; the main components of SDN are OFSwitches and Controller. The traffic flow …

Abstract In Software Defined Networks (SDNs), the global view of the underlying network
topology is created and maintained at the logically centralized controller. SDN achieves it by …

Software-defined networking (SDN) has predominantly become the defacto network
standard for next generation networking due to its flexibility features; through a single-phase …

Currently, software-defined networking (SDN) platforms leverage the link-layer discovery
protocol (LLDP) to discover the underlying topology. However, the LLDP is suboptimal in …

OpenFlow discovery protocol (OFDP) is the standard protocol for discovering network
topologies for OpenFlow. Each controller generates and receives OFDP messages for each …

Discovering network elements in a dynamic and optimized manner and being able to
contend with ever-growing traffic is a key requirement for current networking environments …

Though widely perceived as a promising network architecture, Software Defined Networks
(SDN) have inherent deployment issues, particularly in terms of a full SDN deployment …

Achieving high programmability has become an essential aim of network research due to
the ever-increasing internet traffic. Software-Defined Network (SDN) is an emerging …

Software defined networking is an emerging network architecture that separates the control
plane from the data plane of network devices and places the control plane on one or more …

Software‐defined networks (SDNs) decouple the data plane from the control plane. Thus, it
provides logically centralized visibility of the entire networking infrastructure to the controller …
