In my previous blog, we looked at how Catalyst switches can be used to assess video application readiness in the network before rolling out a video based collaboration application. In this blog, let us take a look at available tools on the Catalyst switches to monitor and troubleshoot video problems in the network.
As we know, fundamentally, video traffic is different from data traffic. Video traffic is more dynamic and bandwidth intensive and even small changes in delay or loss can cause visible disruptions to user experience. Routinely, IT trouble tickets are opened by users that are faced with degraded video experience. To add to that, interactive video is real time. Any delay in troubleshooting will make IT miss the window to rectify the problem. For a firm with many locations and buildings, finding the problem can be complex and time consuming without the right tools.

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.
For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.
The main elements of the onePK software architecture are illustrated Read More »

Be it tax-credits/subsidies in different parts of the world or the recent news of California setting up a carbon trading exchange – no week passes by without the mention of “the importance of saving energy” or “reducing greenhouse gases”. Yet, with the explosion of technology and IP-connected devices; IT consumes over 25% of energy in a commercial building or office.
So why am I writing about this in a Cisco blog and what has this got to do with networking?

While I was participating in a web conference from my home office, I started thinking about how much and how fast things have changed in the last decade around communications and how we use collaboration tools in the office, at home and on the road and most importantly the number of devices available to me so I CAN collaborate over distance.
One thing that stays constant in this industry is change, especially when it comes to devices. Let’s take a walk down memory lane and see if you can remember any of these once “have to have” mobile devices. The Nokia 9000, The Motorola “Flip phone” and The “Razor”, Palm Pilot, dare I say the Blackberry and of course at the start of 2007 the IPhone came on to the market — and we all know how that is playing out — this being a rarity. More recently, Samsung is challenging Apple with the Galaxy and DROID OS is becoming more prevalent than IOS. Last I checked, there was an estimated 1.3 million Read More »
