Software Defined Networking From Blue Sky to Solid Ground CURT BECKMANN EMEA CTO and Chair of ONF Forwarding Abstractions WG BROCADE 30 October 2014 Sequence • A quick review of SDN • What has changed for SDN in the past few months • What to expect in 2015 © Hitachi Data Systems Corporation 2014. All rights reserved. Definitions of Software Defined Networking What is a technical definition of SDN? “A network where the control and data planes are separated.” Misses the main point… because it answers the wrong question A better question is: Why SDN? “An open and interoperable network architecture / market ecosystem that allows control plane products to be purchased independently of data plane products.” This answer clarifies the need for buyer choice, which will drive competition and innovation © Hitachi Data Systems Corporation 2014.

Mar 2013 Sep 2012 July 2012 Oct 2014 Important Points of Understanding • SDN / NFV is very disruptive, moving to ECOSYSTEM model So disruptive that vendor-buyer partnership needed • Disruption driven by huge needs of key buyers: SPs/Web2.0 SPs / Web2.0 buy a lot, but huge needs take time to solve Smaller needs (of SPs or Enterprise) don’t drive the change • But! Smaller needs can leverage the SDN progress I.e. technology built for huge tasks can solve smaller tasks NOW • This is where we are now © Hitachi Data Systems Corporation 2014. All rights reserved.

Southbound Interfaces & Protocol Plugins Brocade Packaged Solutions Licensed Separately Brocade Routers and Switches 11 Other important changes Real progress on southbound interfaces (OF and others) Convergence in OS controllers, with supported distributions Model driven, agile build, scalable and performant Many SDN and NFV trials are (quietly) underway OPNFV formed Many product and system test tools now available Perhaps most important: Maturity of mindset and perspective across the industry © Hitachi Data Systems Corporation 2014. All rights reserved. What to expect in 2015 2015 will be the year of the “SDN part number” Many GA products will ship “Open Vertical” (bundled but standards-based) solutions Partner bundles will also be available SDN Technologies aimed at SPs are getting mature But the technologies are not specific to SP problems Many Enterprise trials and deployments will also occur © Hitachi Data Systems Corporation 2014. All rights reserved. Other thoughts Many storage-oriented challenges can benefit from SDN Cloud was main driver of SDN Cloud also requires storage But main focus of SDN (and NFV) has naturally been on IP As IP use cases stabilize, adaptation to storage will come fast © Hitachi Data Systems Corporation 2014.
