One of the great challenges of SDN – that many in my view underplay – is the change in paradigm from having a vendor deliver your network (hardware + software), to having (potentially) an ecosystem deliver your network – and this ecosystem may require you to develop software to perform network tasks or to integrate various SDN components together. This was recognized quite astutely by consultant Jim Metzler, which I discussed in one of my earlier blogs. “Applications can dynamically request services from the network” is what the SDN evangelists will tell you. Jim astutely asked “How exactly do they do that?”. Well ….. the true answer is that either (i) you need to buy [new] apps that do this off the shelf, as it were, or [more likely today] (ii) you need to modify your apps or develop new apps to do this.
Coding – the New Networking?
So are you ready for procuring apps and/or developing software in your network design team now? Don’t worry if you say “no”. Let me first tell you a few customer reactions to this topic, and then let me update you on Cisco Services can help you develop new SDN apps that solve your specific network challenges.

… is none other than… (drum roll, please!) … our one year old baby, OpenDaylight! My heartfelt congratulations go to the OpenDaylight committers and contributors, the open source collaborators who have poured their heart and soul into this wonderful project. This is indeed a remarkable event, considering the skepticism surrounding its start just about one year ago, in fact at Equinox. The Interop and OpenDaylight announcement captures the meaning of this accomplishment very well and on behalf of the OpenDaylight partners, I would like to thank the developers and users, to wish them continued success and strong adoption. Know that as long as core open source principles are alive and well our project will do well. Thank you, Interop panelists and conference attendees, and most of all, thank you Cisco colleagues, customers, and partners for building and embracing the base of what promises to be a star project. I am so proud of you!

Expecting multi-vendor innovation around next-generation software-defined networking (SDN)? Hear what Cisco and these panelists from leading technology companies have to say:
Cisco CIO Rebecca Jacoby, who’s delivering a keynote at Interop, will also be joining to share her perspectives on technology and how Cisco IT is embracing aspects of Application Centric Infrastructure.
It’s been five months since the seminal Nov 6 announcement of Application Centric Infrastructure and the momentum keeps accelerating –
- Nexus 9508 ships – Nov 2013
- 800+ Nexus 9000 customers in pipeline
- Over 30 ACI ecosystem companies – Jan 2014
- Miercom performance benchmark records for Nexus 9516
- ACI training programs for partners to empower 2 million CCIE/CCNA trained network engineers – Mar 2014
- Nexus 9516 and APIC selected as Finalists for Best of Interop – Mar 2014
- Next?? Tune into the webcast for more..!
To put great technology solutions into real world perspective, we will also be joined by several of Cisco’s customers from different segments and deployment models, providing insights into their experiences and best practices.
Join me and the rest of the Cisco team, as we continue to redefine the power of IT. April 2nd at 1 PM PST.
Already Attending Interop?
If you’re already attending Interop in person, please join me and the rest of the Cisco team for this live broadcast at the Mandalay Ball Room at 12.45PM.

Many of the existing switch and wireless infrastructures that were deployed 5 or more years ago were not designed for BYOD, pervasive mobility, advanced security, SDN and more. Let us look at these trends and the benefits of upgrading the network infrastructure to the latest switching and wireless products.
BYOD and Mobility
There are multiple dimensions in which BYOD and mobility are pressuring the existing network. An average user now has 3x more devices. A company of 1,000 users seems like a company of 3,000 users. And, Internet of Things devices like sensors, CCTVs, and building automation are being connected to the network. Yesterday’s network cannot sustainably handle the exponential growth of these devices and applications. Upgrade to the latest switches and wireless infrastructure will give you more performance in terms of higher switching capacity, converged wired-wireless access & more processing power to handle the growth of devices/apps. The benefits are network can scale easily to support the influx of mobile & connected devices and their applications and your users get the same excellent experience whether wired or mobile.

- When does ACI make sense for your business ?
For this new episode of the podcast with Cisco Champion, we are fortunate to have a great technical (and casual) dialog between two active members of the data center and cloud social media sphere.
Colin Lynch (@UCSguru) based in London is a subject matter expert for Cisco UCS, Integrated Systems, Converged Infrastructure and writes also on SDN . Colin has an independant blog at UCSguru.com He was nominated ComputaCenter Consultant of the Year in 2013 .
Colin talked with Joe Onisick (@jonisick) who works for Insieme Networks, now part of Cisco. Joe writes an independant blog at DefineTheCloud.com. He talked about ACI in multiple videos and podcasts.
After attending Cisco Live Europe in Milan, Colin was at VMware PEX to have an in-depth analysis of NSX , and wanted to “challenge ” Joe on several points, which makes this conversation even more lively !
I found this dialog extremely rich, as both participants were willing to address difficult and controversial aspects of the Data Center architecture today and tomorrow, for instance around layer 2 and layer 3, network programmability and management, or the future of networking certification ! You will also better understand, why Cisco is heavily investing in ACI solutions, when at the same type keeps developing other paths .
A very exciting 40 mn conversation between two great subject matter experts, really passionate by this topic, spiced with additional questions from other Cisco Champions and…humor.
Listen now to our guests and enjoy the show hosted by @commsninja.
I also encourage you to read this very didactic explanation from Tom Edsall, Cisco Fellow and CTO of Insieme Networks, in this new blog from Shashi Kiran
ACI Design Principles : The Role of SDN Overlays in Application Centric Deployement . Shashi will publish the second part tomorrow .
As a reminder, Cisco Champion is a community of technical professionals who are passionate about sharing their knowledge and expertise. They are ready to offer their time to help others to learn about Cisco and connect with Cisco in unique way
For Data Center and Cloud , we have now more than 40 members, who have been nominated by peers for one year . We invite them to give their opinion on market trends, Cisco solutions and products . We encourage also them to participate to our Cisco Live events , webcasts, podcasts , Google + HOA , blogs and tweet to share their experience and wisdom.
