What is GENI?

A Nationwide Programmable Facility for Research into Future Internet Technologies

Using a ‘Clean-Slate’ Approach – ‘Out of the Box’ Thinking

Strong Coupling with Physical Technologies – Wireless Networking – Optical Networking

Global Environment for Network Innovation

- share resources to support many simultaneous experiments

GENI Design Principles • Physical network ‘substrate’

– building block components – elements / nodes / links / subnets

• Software control & management framework

– knits building blocks together – allows many parallel experiments (slices) – creates arbitrary logical topologies (virtualization)

• Programmable for ‘Clean Slate’ research • Instrumented for accurate analysis

• Flexible and Phased Design – Support Technology Introduction during GENI Lifetime

What’s Openflow ? • Openflow is an implementation of Software

Defined Network. Openflow defines a clear API interface between the controller and switches/forwarding devices.

Challenges in Openflow

• Designed for network engineers and programmers

• Network monitoring and management • Limited deployment of switches supporting

Openflow(especially in WAN) • Inter-domain

HYBRID Openflow NETWORK

NTU OpenvSwitch (cont’d)

PRAGMA testbed • Provided by PRAGMA • Developed and

implemented by Osaka University, AIST and UCSD

• Setup virtual networks on virtual machines forming Pragma testbed

• Virtual network can be organised using Trema OpenFlow Controller with Sliceable Routing Switch application

• Demonstrated in Pragma22, Bangkok 2013

HON – Hybrid OpenFlow Network

HON-Core (OpenFlow Switches)

HON-Edge (Open

vSwitches)

Lead researcher: Zoebir Bong Aim: To extend hardware-based OpenFlow network with software-based OpenFlow network

• Hardware-based network is an OpenFlow network formed by OpenFlow switches and serves as HON core network

• Software-based network is an OpenFlow network formed by OpenvSwitch servers as HON edge switches

Summary

• Future Internet has progressed – Large International deployment, eg. iGENI – Programmable and Open Interface –

SDN/Openflow

• What has it enabled ? – IN-network services – Resilient network
