Enterprise Networks: Practical Differences in LAN and WAN SDN Deployments

In my last blog I introduced challenges Enterprises are facing in their WAN deployments and the definition of ONF SDN. While the broad definition of ONF’s SDN architecture implies many theoretical answers to these challenges, we need to be pragmatic. Let’s take a look at the practical differences in LAN and WAN networks that affect how you’d deploy SDN on each.  Read More »

Enterprise Networks At CiscoLive Video Interviews Continued!

Hi All!  For this video my trusty film crew and I are still here in Orlando for CiscoLive 2013 and got in some great interviews!  In this episode I learn about Smart Connected Vehicles (and why you shouldn’t hack them),  meet with Chris Tillett (@christillett) of Halifax Media Group and find out why the new Cisco ISR 4451-X is the router for him, I get to sit in and program the Delorean time machine we had in our booth, and JOHN CHAMBERS GIVES ME AND MY TRUSTY FILM CREW A THUMBS UP.  Yes, that needed all caps, because it is awesome and I didn’t even realize it until the episode was posted!  Also, I tested the tensile strength of the CiscoLive sign.

Enterprise Networks at CiscoLive Day1 Recap

Hi Everyone! My trusty film crew and I are here at CiscoLive! Orlando. It has been great so far with the launch of the new Cisco Catalyst 6800 Series, Cisco 4451-X, Cisco ASR 1000-AX, and Sup8E for the Catalyst 4500!  Over the next few days we’ll be doing interviews with some of the awesome people here at Cisco who helped create these technologies, as well as other people doing interesting demos, and some with unique perspectives.

To kick things off, we get a little sittly with the 6800 and I got an interview with Shawn Wargo on what’s exciting about Instant Access.  Enjoy and let me know what you think.

Introducing An Entirely New Direction in Branch Offices

Introducing 4451-X Frickin Awesome 400Thinking about remote site networks in a totally new way.

This week Cisco announced a new member of the Integrated Services Router family.  The ISR 4451-X might not seem that unique at first glance.  Here’s Cisco releasing another new router that adds to their already extensive branch router portfolio – the ISR G2.  However, the newest ISR really is a #GameChanger when it comes to building a modern, future-proof network designed with business critical applications in mind.

That isn’t just marketing fluff in this case.  The ISR 4451-X was designed from the ground up with rich network services and application delivery in mind.  It really is the first platform conceived and built from the very beginning with a laser focus on application experience in a remote branch office.  Maybe we even need a new name because in some ways it really is changing what it means to be a “router.”

The Concept

When we started thinking about designing a new high-end branch router, several things were happening simultaneously with our large Enterprise customers.  First, the role of applications was changing in the network.  With modern business-critical applications being delivered across the wide-area network are now critical for keeping the front doors open, the network is now more critical than ever to businesses of all types.

Let’s Clear Up Some Misconceptions – Is SDN Relevant to the Enterprise WAN?

June is summer weather in the San Francisco Bay Area, but quite different from the June I was used to in Boston. A common misconception around Mark Twain and his relationship with San Francisco summer is that he never said “The coldest winter I ever spent was a summer in San Francisco.” But he did say: “Cold! If the thermometer had been an inch longer we’d all have frozen to death.”

June is always exciting here and in Europe. NBA playoffs are on and the Giro d’Italia just ended with the Italian Vincenzo Nibali winning it emphatically. The San Antonio Spurs have been so good but King James brought the Heat back from a certain death in Game 6. Game 7 decides it all!

Equally exciting is the buzz in networking circles, especially in the Bay Area, around Software Defined Networking (SDN) and how it is potentially commoditizing networking infrastructure. However, just as we cleared up that misconception about Mark Twain, I’d like to clear up some points around WAN challenges with cloud migration and how SDN might be applied to overcome these challenges.

In this blog post I will discuss the challenges in the Enterprise WAN and relevancy of SDN in overcoming these challenges.  In part 2, I’ll cover how the Cisco ONE Enterprise Networks Architecture addresses these WAN challenges. Read More »
