NFV in the NREN Community through GN3+ (and beyond…!)

Michael Enrico

CTO, DANTE

Future Internet Assembly 2014

Athens, Thursday 20th March 2014

2Connect | Communicate | Collaborate

Agenda

A bit on GÉANT (the network)…… which has been reloaded!

A bit on GÉANT (GN3Plus, the project)…… which has also been reloaded!

GÉANT (the community)…… has been reloaded (and expanded) through the GÉANT Innovation Programme including the GÉANT Open Calls

Where is the NFV in GÉANT?


But first a word on DANTE

Delivery of Advanced Network Technology to Europe

A UK-based not-for-profit limited liability company

Created and owned by a number of European NRENs

DANTE plan, build and manage pan-European R&E networks on behalf of the NRENS in Europe

Started in 1993

Based in Cambridge, UK

Currently ~ 70 staff (many nationalities)

Turnover ~ €45M per annum

connect • communicate • collaborate


What is GÉANT? (more than just a network…)

GÉANT is co-funded by Europe’s NRENs and the European Commission (EC) under the Seventh Framework Programme (FP7)

Project Partners are 38 European NRENs, TERENA and DANTE

> 350 (project) staff work in GÉANT across Europe

Wide range of adv services (inc. BoD & IPv6)

25 European POPs

12,000 km of dark fibre on 18 routes

50,000 km network infrastructure on 44 routes

Widely diversified footprint• Serves 50 million users• 10,000 institutions• Across 43 European

countries

New hardware platform choices

Optical Transport Platform Packet Transport & Routing Platform

DTN-X from InfineraPhotonic Integrated Circuit (PIC) based 500Gbit/s “superchannels” with OTN switching

MX 960 from JuniperFlexible & powerful IP/MPLS switching and routing platform


What do we mean by SDN ready?

Various versions of the JUNOS operating system for the Juniper MX have supported the OpenFlow wire protocol interface for some time

e.g. generally available (and supported) JUNOS 13.3 (R1.6) with the addition of another package (jsdn-i386-13.3R1.6) supports OpenFlow wire protocol v1.0

this is currently being tried out in the DANTE lab in Cambridge

not yet out in the (GÉANT) field

Infinera have their Open Transport Switch (OTS) agent that can be installed on the DTN-X platform

this supports various versions of the OpenFlow wire protocol (some with proprietary extensions, some without)

this allows circuits to be provisioned in the “Transport SDN” paradigm

again, not yet out in the GÉANT field

Note: many (non-packet) transport switch vendors claim to have been using “SDN” (in some sense) for a long time by dint of the fact that they have been using centralised NMS-based management since time began…

ARES Project – implements “NFV”

University of Perugia & GGB

Implementing an advanced CDN using NSIS to signal the instantiation of (virtual) resources when and where they are needed to help deliver content


SDN/NFV – where are the users?

Much of the effort in this field is driven by the possibilities offered by the technology – not an immediate user demand

This was also the case for Lambda networking and IPv6 in the early days of these services. Today, however, everyone recognizes the need for these services.

Having said this, the users are there already – from radio astronomy and other types of massive data transfer to more complex service scenarios

e.g. advanced & dynamic CDN service example shown previously but this applies to many more applications than just the genomics in this particular case

The combination of Cloud Services and SDN/NFV will be increasingly interesting, and GÉANT can expect to serve as a showcase for the rest of society, when cloud vendors with NREN customers start making substantive use of SDN/NFV technologies.


Summary

SDN/NFV (“Software-isation”) is

The next technology wave to re-define networking…

…and make it sexy once again (;-)

Important as a forefront technology

A field where GÉANT really can contribute

JRAs, open calls (next round ~2016), TaaS(es)

A challenge to implement across multiple domains/operators

GÉANT service area (MD) ideal for this (with caveats…)

An area for R&D activities for years to come
