The Path Forward for Software Defined Networks

OpenFlow SDN is simple and elegant

3

What’s the Business Value in Openflow/SDN Independent Software Vendors provide Virtual Appliances on standard high volume servers and storage

Today’s network is a fragmented mix of proprietary software and hardware appliances High touch, low service velocity and slow to deploy High cost of development is stifling innovation and emergence of new vendors

Open interface standardized forwarding planes provide commonality, scale and capex/opex efficiencies – zero touch provisioning

Design, deployment, management and service velocity all benefit from a common approach

Firewalls

WAN Optimization

Load Balancers

Service Aggregation

DPI

DDoS, Attack Mitigation

Session Border Controllers

Routers/Switches

Why do I need this if this is sufficient?

And no, you can‘t do this

Reality is a little uglier

And then a miracle occurs

Upcoming trends

2009 2014 2013 2016 2015

Incubation, OF1.0 thru 1.X releases, controller wars begin

OpenFlow 1.3 released

TTP Development and controller/data plane interoperability testing

Commercial grade controllers from HP, NEC, Opendaylight ...

Commercial grade applications and systems for WAN/Enterprise/Telco

Network Appliance vendors transition to become Network Application vendors

No commercial grade data plane or controller = no commercial success
