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 »

Announcing the SCTE IP Challenge

By Daniel Howard, CTO and SVP, Engineering of SCTE

As you know, the Society of Cable Telecommunications Engineers (SCTE) continues to strive to provide new and unique ways to both train and challenge the cable workforce and our members.   Through our Chapters, we have been holding a very successful Olympic-style challenge for field-level employees that includes both hands-on skill assessments and knowledge-based contests, and this continues to be a big hit with our members and the industry.  But one thing I kept hearing in meetings with cable executives, managers and at SCTE chapters was the need for SCTE to provide resources and involvement opportunities for the IP engineers and computer scientists in our workforce who manage an increasingly larger portion of the overall network.

I’m therefore proud and excited to announce the new SCTE IP Challenge that we developed in partnership with Cisco as a response to this need.  This new interactive event was created to drive awareness of the importance of foundational IP knowledge among the cable workforce, and it is designed to promote the benefits of IP expertise in the cable industry, as well as leverage thought leadership around IPv6 in particular.
