Proceedings ArticleDOI
The controller placement problem
TL;DR: This paper examines fundamental limits to control plane propagation latency on an upcoming Internet2 production deployment, then expands the scope to over 100 publicly available WAN topologies and finds that one controller location is often sufficient to meet existing reaction-time requirements.
FlowVisor: A Network Virtualization Layer
Rob Sherwood,Glen Gibb,Kok-Kiong Yap,Guido Appenzeller,Martin Casado,Nick McKeown,Guru Parulkar +6 more
TL;DR: This paper builds a research platform which allows multiple network experiments to run side-by-side with production traffic while still providing isolation and hardware forwarding speeds and presents a new approach to switch virtualization in which the same hardware forwarding plane can be shared among multiple logical networks, each with distinct forwarding logic.
Proceedings Article
On controller performance in software-defined networks
TL;DR: A split architecture in which the control plane is decoupled from the data plane is referred to as Software-Defined Networking (SDN), which provides a more structured software environment for developing network-wide abstractions while potentially simplifying the data planes.
Proceedings ArticleDOI
Can the production network be the testbed
Rob Sherwood,Glen Gibb,Kok-Kiong Yap,Guido Appenzeller,Martin Casado,Nick McKeown,Guru Parulkar +6 more
TL;DR: A way to build a testbed that is embedded in--and thus grows with--the network, and if unmodified hardware supports some basic primitives, then a worldwide testbed can ride on the coat-tails of deployments, at no extra expense is described.
Journal ArticleDOI
Carving research slices out of your production networks with OpenFlow
Rob Sherwood,Michael Chan,G. Adam Covington,Glen Gibb,Mario Flajslik,Nikhil Handigol,Te-Yuan Huang,Peyman Kazemian,Masayoshi Kobayashi,Jad Naous,Srini Seetharaman,David Underhill,Tatsuya Yabe,Kok-Kiong Yap,Yiannis Yiakoumis,Hongyi Zeng,Guido Appenzeller,Ramesh Johari,Nick McKeown,Guru Parulkar +19 more
TL;DR: FlowVisor is demonstrated, a special purpose OpenFlow controller that allows multiple researchers to run experiments safely and independently on the same production OpenFlow network and four network slices running in parallel.
