Networking 101 – New Playlists

April 27, 2012 at 9:20 am PST

TechWiseTV Playlist

We updated our little corner of the Cisco YouTube page with some new playlist categories.  Now its easy to find my favorite quick hits -- Networking 101.

Couple of great new videos have been up here recently as @jimmyray_purser rolls ‘em out!

Networking 101: What is an ASIC?

Is a custom application specific integrated circuit (ASIC) really a big deal in networking devices? Jimmy Ray Purser walks us through the difference between custom and full custom ASIC designs. Watch an overview of the steps involved in ASIC design. Learn the the difference between “programmable” ASICs and how to determine the difference between various ASIC models.

Networking 101: Quality of Service

How well do you know QoS? We all throw the term around but are we all truly comfortable with it? Jimmy Ray breaks it down at the packet level and shares the one rule you must never forget.

Networking 101: Switch Latency

Understanding how switch performance is measured can make the difference with application performance. The terminology of switch latency in various switching methods and the methodology to obtain the most accurate latency measurements make it easy to play games with the numbers. Watch this episode of Networking 101 with Jimmy Ray from TechWiseTV and arm yourself with knowledge.

No Traffic with Application Visibility and Control

I love my job, but I really don’t enjoy my commute….and the unpredictable traffic. Living on the west side of San Francisco and working on the east side of San Jose, Google Maps tells me my journey is a hefty 47.2 miles and 1 hour and 1 minute (without traffic.) Holidays, rain, and accidents can add minutes and sometimes hours.

Twice a day, to and from work, I start asking the questions:

  • How busy is it on the road right now? Is the road full of tired commuters, semis, or concert traffic?
  • Which lane should I be in? If I’m in the fast lane, what are the odds of it coming to a screeching halt while I watch the other three lanes go by?
  • Do I need to detour to another interstate or highway due to an accident or concert?

Virtual Switching: Fundamentals of VSS

December 14, 2011 at 6:22 am PST

Cisco’s been doing virtualization in various forms on the network side for quite a long time. One incredibly powerful feature that I think is still amazingly under utilized is the Cisco VSS or Virtual Switching System.

The ability to make two 6500′s look like a single switch so that you can have your cake and eat it too.  Its the epitome of giving us the redundancy and availability we need while simultaneously allowing us to use the extra capacity that could normally sit unused. Easier management and configuration make this a no-brainer that more network managers should consider as ‘required’ in their design. Check out our ‘Fundamentals of VSS‘ to get yourself started.

Even more after the jump…

Part 2 of “A deeper dive into Cisco VXI finds Cisco WAAS”

Dateline Barcelona, Catalonia, Spain.  Citrix Summit and Synergy, October 2011
Hi again,
Last post I said I’d get back to you to give you, at least, my opinion of why Citrix and Cisco are partnering up.  As you might have seen from the dateline above, it’s easy to find out when you get to Citrix Summit and Synergy.  It has to do with the global and ubiquitous Cisco networks deployed by organizations everywhere.  Citrix is doing great with XenApp (last I heard, well over 50,000,000 licenses) and is poised to do even better with XenDesktop.

Continue driving the Internet of Things

So, in my last blog, I pointed out that Manufacturers, and particularly car makers, will be driving the Internet of Things (IoT) by incorporating standard networks into their machines.   I also indicated that evolving the standards is going to be critical to that adoption.

Applying standard networks (by that I mean Ethernet, IP, TCP/UDP, 802.11/WiFi, etc.) machines is going to be a distinctly different than the networking of computers, phones and the plethora of tablets and handheld devices that has driven the Internet and standard networks to date. Read More »
