Networking 101: DNS Revealed

June 1, 2012 at 5:49 am PST

Two great new ‘Networking 101’ videos now available.  This series is great for anyone needing a quick refresh or touch up on the basics and these two both focus on DNS.

DNS is key to making the Internet accessible to us humans. It’s how we can connect to techwisetv.com without needing to know anything complex from anywhere in the world. How does it know how to do this? DNS can be a complicated topic but understanding the basics does not have to be.

Taking it a step further, DNSSEC is a suite of IETF specifications designed to guarantee the authenticity of data obtained from the domain name system (DNS). Although not designed for confidentiality of the data, this protocol is a great answer for many of the ills that threaten the simplicity of the Internet. Chief Geek Jimmy Ray Purser arms you with how it works and why deployment is not growing as fast as it should be.

Fundamentals of 802.11ac

May 12, 2012 at 7:44 am PST

We released our latest in the Fundamentals series earlier this month and it is trending quite well.  The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!

Three good stories worth covering, the first two on security!

BYOD Security with Bill McGee

Get more info on the Cisco Security BYOD components, one of which I (humbly) recommend is our ‘Fundamentals of ISE’ (The Cisco Identity Services Engine)

Our second story in security is easily one of my favorites and not just because it involves a lot of friend from Austin.  Cisco’s Security Intelligence Operations…

Fresh Video from the Interop Show Floor in VEGAS!

May 9, 2012 at 5:20 am PST

Chattin with Prashanth at Interop Vegas

Having a lot of fun this year at Interop 2012. We are shooting and editing in a much tighter workflow so that we can publish these things same day and thank gosh!  The stories are numerous and oh so timely.   Follow along as I attempt to recap our first full day on the show floor.

Meet PAM

Jim Frey recently wrote a white paper called Closing the Loop for Effective Network Operations Management and he stopped by to chat about some of the key points made.

As he describes it: Cisco has developed and introduced Prime Assurance Manager with one essential goal in mind – to provide end-to-end operational monitoring visibility, spanning data center to and through the branch, as a means for facilitating efficient operations and proactively protecting network-delivered applications and network availability, network performance, application performance, and end user experience data across both wired and wireless environments, coupled with troubleshooting and reporting features.

Jim is going to be going even deeper with an hour long seminar on May 15.

Yair Dolev was our guest for the topic of ‘Intelligent Automation for the Cloud’ now in a cool starter Edition!
