Based on the online dialog on Easy Virtual Network (EVN) that I’ve seen, it appears that some people still have questions. We thought our story was as simple to understand as EVN is to use, but there is a need for clarification. Here’s a bit more information about what EVN is and what it isn’t.
One online comment was, “It’s a Cisco proprietary version of MPLS for the enterprise.” No, we believe in MPLS. It’s supported on a number of Cisco platforms and is used by many of our customers. MPLS is the most scalable and perhaps the most capable means of network virtualization. But it’s also overkill and far too complicated for many enterprises.
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?
I am back from a week at Cisco Live London where I presented to a packed room on Enterprise IPv6 Deployment. I added much more emphasis on Internet Edge design this time around and it was VERY well received. The comments were very positive, as were the questions in the room, regarding the Internet Edge as the primary starting point for the majority of the attendees. You can check out details on my IPv6 Internet Edge content at my previous blog post.
In addition to IPv6 in the Internet Edge, IPv6 security was a hot topic as usual. Excellent Cisco speakers such as Eric Vyncke provided attendees at Cisco Live very detailed guidance on securing their networks when using IPv6. One thing that we have come to realize, not just for security, but also for all areas of IPv6 deployment, is that we cannot assume too much regarding the knowledge level of people attending our sessions.
I recently went to New York for the National Retail Federation Conference and I took a picture of all the devices (excluding my laptop) that I carried with me for use at the hotel, in the booth, and while I was at 30,000 ft.
As I think back about working with multiple devices (both issued to me and owned by me) during the week, here are some areas that impacted IT.
Cisco Live! It’s always an exciting time – real customers, sharing real world experiences, looking for news that will make their networks stronger, faster, more capable, more efficient. And for this Yank, visiting ExCeL London in the heart of London’s Royal Docks for the first time, it’s a special treat.
There are a number of announcements coming out of Cisco Live this week – two that build on the story we’ve been telling about the Catalyst 6500… a new 40 Gigabit Ethernet module and 160 Gbps per slot performance in existing Catalyst 6500 E-Series chassis.
