I was excited to attend the Open Networking User Group Conference last week at Columbia University in New York. The Open Networking User Group is a community of IT business leaders who exchange ideas and best practices for implementing Open Networking and Software-Defined Networking (SDN) designs. One of the ONUG working groups is the SD-WAN Working Group which was my main interest for attending this event. The SD-WAN working has determined a set of 10 business requirements (based on user-developed use cases) that Enterprises should consider when evaluating SD-WAN solutions:
Ensuring application experience at the branch is a daunting task. IT must look beyond traditional WAN challenges (like bandwidth, transport type, and speed) to applications experience. As time-to-market becomes a pillar of enterprise’s competitive advantages, application experience is key to ensuring fast service and high customer satisfaction.
In today’s connected world, users demand instant connectivity and seamless experience. As the business innovates, the burden on the WAN intensifies, yet three-fourth (75%) of today enterprises say their bandwidth budget will remain flat. IT knows this, and they plan ahead. They evolve their network into a hybrid WAN (see Figure 1), utilize the latest technologies, but application performance still suffers. Why?
This week, May 13-14, ONUG, or the Open Networking User Group, will meet at Columbia University’s Alfred Lerner Hall in New York City, NY.
ONUG is the leading user-driven community of IT Business Leaders, CTOs, network architects, especially including those implementing SDN, who are focused on leveraging the power of their engineering and procurement to influence the pace and deployment of open networking solutions.
If you are planning on attending, I’d like to provide you with a quick overview of the activities Cisco will be participating in at the Open Networking User Group.
On conference day 1, May 13, the SD-WAN and the Virtual Network Overlay Working Groups will present their top ten findings and present their work.
Check out the SD-WAN Working Group Update with Cisco speaker, Steve Wood, Principal Engineer, Enterprise Routing, from 10:00-10:45 am.
Then during the Technology Showcase Break, meet Sumanth Kakaraparthi, Product Manager, Enterprise Routing and Bill Reilly, Technical Marketing Engineer, Enterprise Routing who will deliver an IWAN/SD-WAN Demo at the Cisco demo station.
Next, attend the Virtual Networks/Overlays Working Group Update with Cisco speaker, Mike Cohen, Director of Product Management, Insieme Networks, on May 13 from 12:00-12:45 pm.
Following these updates will be a luncheon presentation: “Faster WAN Delivery: Software Defined WAN-as-a-Service” on May 13 from 1:30-2:30 pm delivered by Cisco speaker, Jeff Reed, VP, Enterprise Infrastructure and Solutions Group. Jeff will be joined by partner speakers: Jeff Gray, Glue Networks CEO and Matt Cook, Forsythe Sr. Director – Network & Workspace Solutions.
From 4:05-5:00pm, there will be a lively debate on “Closed vs. Open Source Software” moderated by Ernest Lefner, Bank of America, between Charles Giancarlo, Silver Lake, taking the Pro Closed position and Lew Tucker, Cisco VP/CTO for Openstack, taking the Pro Open position. You can carry on the debates yourselves afterwards at the Cocktail Reception from 5:00-7:00.
The next day on May 14 from 2:45-3:45 pm there will be a Town Hall Meeting with leaders from Facebook, Ansible, Nuage, vArmour and our own, Mike Dvorkin, Cisco Distinguished Engineer, Insieme Networks, who will all speak on “Will the DevOps Model Deliver in the Enterprise?”.
Finally, that evening join us at a Cisco Sponsored After Party from 5:00 – 9:00 pm.

Last week, I concentrated on how to use Cisco Prime Infrastructure to do troubleshooting for your network. Today, as the 5th and final post of my 5-part blog series, I’ll look at how to maintain network health for your branch site users with Prime. As a quick recap, here’s my blog series on how to set up networking with Prime for a new branch site.

Converged wired and wireless – blog 2

Troubleshooting – blog 4
Network health – blog 5 (this blog)
As designed, you have successfully brought up your new branch site and the network is now in production. And you are well prepared to troubleshoot if anything goes wrong. Before you declare “mission accomplished”, there is one more step you can take to achieve long-term success. Just like preventive healthcare can help a person to stay healthy, Prime gives you a number of tools to monitor and maintain your network health. By making full use of these tools, you are prepared to address potential issues before they impact your network.
With Prime, you can
– Keep track of network changes with network topology maps and Device 360° Views;
– Maintain centralized visualization across multiple Prime instances with Operations Center ; and
– Stay engaged with Cisco support integration.
One of the things that always excites network engineers and managers is an accurate network topology map. Prime Infrastructure can provide such a map for you, which includes all your branch sites and main campus site. If there are any changes, you’ll know right away. Or, if you want to know more details, you can drill down to each networking device with Prime Device 360° View. The chart below shows a portion of Cisco’s production network topology map. Read More »
Interop is just around the corner. I am sure there will be plenty of thought provoking content about how to transform IT, compelling demos, and SDN everywhere. But let’s not forget the reality of most IT organizations today.
The majority face the fact that digital innovation is overwhelming their enterprise network. Everything from internal and external Web apps, SaaS, HD video, software updates, mobile apps and even digital signage are traversing the network eating up valuable bandwidth. Analysts even predict that average enterprise bandwidth requirements will increase by up to 50% per year while 60% of WAN budgets are flat or declining.
In addition most enterprises seem to subscribe to doing more with less – particularly when it comes to IT – so upgrading enterprise network bandwidth across locations every few years just isn’t viable – both from a budget and agility perspective. That is not to mention that a lot of enterprises can’t upgrade their bandwidth even if they wanted to due to branch location. Read More »
