On Controller Performance in Software-Defined Networks

Network architectures in which the control plane is decoupled from the data plane have been growing in popularity. Among the main arguments for this approach is that it provides a more structured software environment for developing network-wide abstractions while potentially simplifying the data plane. As has been adopted elsewhere [11], we refer to this split architecture as Software-Defined N...

POSTER: Performance Management in Application-controlled Software Defined Networks

Software Defined Networking (SDN) is an emerging new paradigm that allows for an application-driven control of network resources. Traditional network management systems (NMS) can benefit from an application-controlled SDN approach, which promises to drastically reduce OPEX by translating application requirements into network behavior without human intervention. However, delivering predictable p...

Software Defined Networks

In previous chapters we have seen why SDN is necessary and what preceded the actual advent of SDN in the research and industrial communities. In this chapter we provide an overview of how SDN actually works, including discussion of the basic components of a Software Defined Networking system, their roles, and how they interact with one another. In the first part of this chapter we focus on the ...

Virtualization in Software - Defined Networks

H osted cloud computing has signif icantly lowered the barrier for creating new networked services. Likewise, experimental facilities such as the Global Environment for Network Innovations (GENI; www. geni.net) let researchers perform largescale experiments on a “slice” of shared infrastructure. By letting tenants share physical resources, virtualization is a key technology in these infrastruct...
