The guys from No Strings Attached Show just published their podcast we sponsored featuring Jim Florwick yesterday and already the verdict is in: Jim Florwick is awesome.
For those of you who haven’t had the chance to download the podcast yet (What are you waiting for?! Download podcast) or you have a few extra minutes to scan a short blog to decide whether or not you want to download the podcast, I asked Jim what his key takeaways are when it comes to high density design.
Here are Jim Florwick’s 6 tips for HD network design (for the REAL meat, tune into the podcast):
- High density client environments are quite common with today’s users being very connected – today’s users are always connected. With planning, this can be managed quite successfully. Understand the limitations, be aware of how legacy requirements will affect the outcome, and set expectations accordingly. Efficiency is key and removing some of the blockers (legacy) first is essential.
- 802.11ac represents another quantum leap forward in technology and will eventually allow a much richer user experience. It is a transition that must be managed and balanced against your current mission requirements. Evaluate channel/bandwidth requirements carefully. Monitor the mix of client devices operating in your environment and update frequently. Read More »

In my last post, I discussed the importance of a strong network foundation. Let’s get a little deeper into this now. The strategies depicted in the diagram below have been developed over nearly two decades of Cisco Services experience in the field. These outline what MUST be addressed in order to successfully and fully optimize your investment. Omission of any one will induce risk into the project. I will highlight this as we pass through the strategies.

Another year, another CiscoLive. This was the last year in the London venue, and since it was the third time we did it, we had a chance to incorporate learning from the previous two years. As a result, I would say the network was quite a success.
The key element of the design, led by Mark McKillop, was the balance between showcasing the latest technology and maintaining the simplicity of the network. This year we had a mixed L2 + L3 core design. This design helped decrease the impact of various parts on each other. The L2 core was in place for the “special-case” requests, which a routing-based infrastructure could not help with. Read More »

Do you think hybrid clouds look like your granny’s network too? Well, that may be extreme, but there is no doubt that hybrid clouds are networked in ways we saw things connected a decade back. Consider a recent example I came across while discussing cloud adoption at a large global enterprise headquartered in the US. Their Asia office wanted to deploy a regional application for local use. It was impractical to deploy it at one of the two large data centers in the US since user experience would be sub-optimal due to latency issues. Hence they chose a local cloud provider to host the application. Sort of a hybrid cloud situation. So what? Read More »

I’ve been in the wireless industry a long time. Like a really long time, ie., twenty years or so. Hard for me to believe, but there it is. It’s been a heck of a great ride for me and my family. One of the most memorable experiences I had was to spend half of a day discussing the relationship between string theory and wireless propagation with a small group of physicists.
That discussion has continued on in one form or another for some years now. Though I don’t engineer many wireless systems these days, I still enjoy a hearty discussion on RF theory about as much as I ever did. One of the current threads in that discussion pertains to complex adaptive systems (CAS). The ultimate complex adaptive system is the human brain. Definitely recommend you read an incredible book called, “The Shallows” by Nicholas Carr which illuminates how our brains are affected by the time we spend online. Fascinating.
