Enhancing Software-Defined Networks with Intelligent Controllers to Improve First Packet Processing Period

Software Defined Intelligent Building

The networks of intelligent building are usually consist of a great number of smart devices. Since many smart devices only support on-site configuration and upgrade, and communication between devices could be observed and even altered by attackers, efficiency and security are two key concerns in maintaining and managing the devices used in intelligent building networks. In this paper, the autho...

Small-Packet Flows in Software Defined Networks: Traffic Profile Optimization

This paper proposes a method for optimizing bandwidth usage in Software Defined Networks (SDNs) based on OpenFlow. Flows of small packets presenting a high overhead, as the ones generated by emerging services, can be identified by the SDN controller, in order to remove header fields that are common to any packet in the flow, only during their way through the SDN. At the same time, several packe...

Programmable and Scalable Software - Defined Networking Controllers

Programmable and Scalable Software-Defined Networking Controllers Andreas Richard Voellmy 2014 A major recent development in computer networking is the notion of Software-Defined Networking (SDN), which allows a network to customize its behaviors through centralized policies at a conceptually centralized network controller. The SDN architecture replaces closed, vertically-integrated, and fixed-...

Attacking Software-Defined Networks: The First Feasibility Study

In this work, we demonstrate an effective and efficient attack against software-defined networks with the knowledge of some basic characteristics of the SDN technology. Essentially, since the control plane is separated from the data plane in a SDN network, the data plane will typically ask the control plane to obtain flow rules when the data plane sees new network packets that it does not know ...
