Flow Sampling: Network Monitoring in Large-Scale Software-Defined IoT Networks

Decentralized Solutions for Monitoring Large-Scale Software-Defined Networks

Software-Defined Networking (SDN) technologies offer the possibility to automatically and frequently reconfigure the network resources by enabling simple and flexible network programmability. One of the key challenges to address when developing a new SDN-based solution is the design of a monitoring framework that can provide frequent and consistent updates to heterogeneous management applicatio...

Software-Defined Fog Network Architecture for IoT

Rapid increase in number and diversity of Internet-connected devices raises many challenges for the traditional network architecture, which is not designed to support a high level of scalability, real-time data delivery and mobility. To address these issues, in this paper we present a new model of Internet of Things architecture which combines benefits of two emerging technologies: software-def...

Floware: Balanced Flow Monitoring in Software Defined Networks

OpenFlow is a protocol-implementing Software Defined Networking, a new networking paradigm, which segregates packet forwarding and accounting from the routing decisions and advanced protocols. This segregation increases agility and flexibility and reduces operational expenses of the networking infrastructure. Despite the apparent benefits, many companies are unable to upgrade their networks to ...

Large-Scale Programing Code Dissemination for Software-Defined Wireless Networks

Controller Placement in Software Defined Network using Iterated Local Search

Software defined network is a new computer network architecture who separates controller and data layer in network devices such as switches and routers. By the emerge of software defined networks, a class of location problems, called controller placement problem, has attracted much more research attention. The task in the problem is to simultaneously find optimal number and location of controll...
