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

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
