Network Operations Centers can be somber places. I’ve seen quite a few during my last two decades in technology. To monitor and manage a vast network is equal parts nerve racking and mind numbing boredom as you stare at wall-to-wall screens, waiting for an alarm to go off.
Over the years, networks have grown to be more and more complex because there are so many interdependent factors that affect their behavior. These factors include traffic flows, network typologies, network protocols, hardware, software, and most importantly, the interactions among them.
More frightening, the steps required to do these very complex network-wide changes are in many cases still manual. In most enterprises this is done box-by-box one at a time – both time consuming and error prone. On top of that you’ve got to make sure that you’ve calculated for variance with lots of different flavors of swtiches and routers in the field. For example, to leverage a powerful feature such as Performance Routing (PfR), which can double your capacity, each WAN router must be properly configured and the overall WAN architecture adapted to the applications requirements. This can take many man-hours to implement, troubleshoot and optimize – which explains why most IT organizations spend 80-90% on operations, leaving little time for much needed innovation. Add in security, QoS, and mission critical applications and within seconds you can see this akin to kicking a sleeping beast. Once we move to the massive number of devices that are expected for the Internet of Things (IoT), then it simply becomes an unsustainable exercise in failure. Read More »

Missing CiscoLive? Learn what’s new!
According to the Open Network User Group (ONUG), a consortium of IT leaders including Bank of America, Fidelity Investments, JP Morgan Chase, UBS, and Gap, among the top priorities to reduce network expenses was WAN management, coming it at #3.
This should not be a surprise with the growth of bandwidth demands from cloud, mobility and rich media applications like video. In fact, 68% of IT decision makers expect their WAN demand to grow. However, few (1 of 4 IT organizations) will have addition budget to pay for it.
Next week, over 5000 IT leaders will be meeting at CiscoLive Milan to find out how to prepare their organization for the opportunities ahead, and build a next-generation network. One essential element is building out a next-generation WAN.
For attendees making their way to the show, here are few sessions and demonstrations to note in your show planner.

Tuesday of CiscoLive Milan (#CLEUR for the Twitter among you) the keynotes will be wall to wall Rob with Rob Lloyd at 9:30 followed by Rob Soderbery at 11:15. These should be pretty interesting and give you a good foundation to where Cisco is headed overall and specifically in our core networking.
Opening Keynote with Rob Lloyd,President of Development and Sales, Cisco
Tuesday, Jan 28, 9:30 – 10:45AM
Hear from Rob Lloyd on how Cisco and the ecosystem of Cisco’s partners are uniquely positioned to connect the unconnected with an open standard and an integrated architecture from the cloud to end devices. Rob will share his vision of the Internet of Everything and examine the industry trends and technologies that are making that vision a reality.

Over the weekend I had a brief twitter chat with someone who mentioned he had been wondering ‘what the heck is IWAN?’ (I’m paraphrasing here) and hadn’t been able to find anything on it. Besides asking the obvious -- why he hadn’t asked me or @CiscoEnterprise about it -- I thought I’d put together a brief on IWAN. Here, you’ll find the top 7 items to get you started learning about IWAN. Also, just wanted to put in a plug for Cisco Champions for Enterprise Networks - you can still nominate yourself or a colleague and one of the perks is that we’ll be making sure to do briefs and/or deep-dives on our solutions with Cisco Champions so you’re in the know.
First, what is the “I” in IWAN? Intelligent. (The I doesn’t refer to “i” as the Pods, Pads, and Phones and should be written upper case, not lower.) We’re calling the capability to use both internet and MPLS for your WAN as Intelligent WAN (IWAN). This idea comes as a result of the confluence of the forces hitting *right now* you’ve probably already heard about that I’ll may over simplify. Skip to the pretty list if need be or check out this intro to the CVDs that has 5 great use cases for IWAN on pages 2 and 3. Read More »

You want to do what?
Enterprise networks are special. They require bomb-proof design, micro-second convergence and service-level agreements so good that the WAN will only be down for half a second every year scheduled six weeks ahead of time for midnight over a holiday weekend. That’s what we’re taught from the time we’re young Network Engineers sitting on our parents’ knees. An Enterprise network is something special they taught us. We should never consider running our mission-critical traffic over the dirty, unreliable Internet! Such talk would be blasphemy akin to looking for a date at a funeral. It might work for some, but our network is special and must be treated that way.
So what is all of this talk then, coming from Cisco no less, of using Internet links to run an Enterprise-class network? Cisco recently introduced the Intelligent WAN (IWAN) solution that promotes exactly this sort of “illicit” behavior. So what’s changed?
