virtualisation
DC Fabric
• OpenFlow DC Fabric evaluation (2012, not mature enough)
DC Network virtualisation & Architecture:
• SDN Overlay: L2-L4 DC Network Virtualisation & DC Architecture
Live

L3 CPE router virtualisation (pre-NFV, PE based)
• virtualisation of the L3 CPE functionality (Internet access / IPVPN)
NFV: RFI & PoC in 2014, TAT completed mid 2015
• Use cases: vL3CPE / vDC Appliances (FW/LB) / vControl Plane (BGP
RR)

WAN SDN Network (Optical/Ethernet/IP):
• Modular MSP (Integrated L2/L3 WAN Network)
• NOVITAS Development:
• End to end WAN network abstraction & full automation in a multi-vendor,
multi-layer environment

Compute Stack Shared Cloud or build an Infrastructure Cloud/PODs ?
Data Centre Fabric Build on the same fabric, produce a seed/small scale version
OSS and MANO
We need to get to a simpler target architecture faster
“Temporary” complexity is not really “temporary”
Benefits
New services and unit cost reductions – you need both
Commercial models that work for all parties
Architecture Back to the drawing board. Many, many times
Development Making DevOps work
Transformation As much a result of this as a key enabler

5. Novitas vision

Elastic
Bandwidth
Deliver programmable elastic links with
variable bandwidth.
Elastic
Topology
Deliver programmable flexible topologies
based on overlay and underlay networks.
Elastic
Edge
Deliver virtualised off-net and on-net L2 and
L3 edge services on top of basic connectivity.
This will change the nature of today’s network:
Self-
provision
Near real-
time
Interworking
with other
providers
Available
through portal
and APIs
Supports
value added
services
Provides
performance
analytics
And will deliver important benefits:

Is MPLS dead ?

9. 19 October 2015 L123 SDN 9
No.

10. 19 October 2015 L123 SDN 10
Do we need to
rethink IPVPN ?
