Worth Reading
For whatever reason, we seem to have moved into the “summer doldrums” a bit early this year. Emails seem to just not being answered for weeks — if ever — several friends have emailed me in the last week or two ago asking if it was just them, or if the IT industry was going crazy. All that said, though, there is still a lot going on in the world of IT.
Geoff Huston — if you don’t follow the rantings of Geoff, you really should — makes a point I wish I’d thought of first. The Internet of Things isn’t necessarily a security risk so much as it’s just a stupidity risk. He uses the example of millions of smaller home based devices being shipped with hard coded IP addresses that impact time and DNS servers to make the point that once things are deployed, they don’t tend to be touched. “If it ain’t broke, don’t fix it.” He calls it the Internet of Stupid Things.
Along those same lines, I saw an article this week about how Microsoft is threatening the end of the world (or some such) because they’re ending support for Windows 2003 server. The Continue reading
Nuage Announces Underlay/Overlay Event Management Platform
During the ONUG event I met with Dimitri Stiliadis, the Co-Founder & Chief Technology Officer of Nuage Networks, who was excited to tell us about the latest product release, the Virtualized Services Assurance Platform (VSAP).
Virtualized Services Assurance Platform
The history of Nuage products has been fairly straightforward; they began with a virtualized networking solution targeted at data centers. More recently, Nuage Networks announced an expansion of that product into the branch office space. What was missing though, was a good way to monitor and manage the complex environment that was built, from underlay to overlay, from the WAN all the way to from virtual switch. When failures occur, they can be difficult to track down or, worse, you are flooded with alerts and left to figure out which ones are actually important, and which ones are the true root cause. To that end, Nuage Networks’ VSAP aims to provide visibility of the network and event correlation so that you can see what might be affected by a given network event.
VSAP is composed of two main components:
Route Monitor
The Nuage Route Monitor uses route protocols to peer with the production network in the data center, backbone, and anywhere else Continue reading
Wi-Fi Design and Capacity Planning Webinars, May 19th and 21st
Please consider attending webinars I'll be hosting on Wi-Fi design and capacity planning next week with Aruba Networks. I'll be talking about the key aspects to WLAN performance and the approach that I take to integrating coverage and capacity into a holistic design, as well as tools you can use to monitor WLAN performance after deployment to maintain a high-performing network and plan for growth.
These won't be traditional marketing webinars. If you're like me, you get invited to (and avoid) many webinars because they are too sales oriented and lack relevant engineering content. This isn't that. The goal of these webinars is to provide practical, real-world concepts and methods to help you design better Wi-Fi networks. Everyone deserves better Wi-Fi, right?

Why and Where Ring topology is used ?
Ring topology is used mostly for economical reason. It is very common topology in the service provider access, and it is not so uncommon in Aggregation and Core ( Backbone ) networks as well. Long haul links are expensive thus in order to provide last mile connectivity in the Service Provider access domain, nodes might… Read More »

Push and Pull Based Control Plane Mechanisms
Control plane packets are used to build a communication path between the networking devices. In some cases control plane is used to advertise and learn the endpoints. Imagine a network which consist of these networking devices, in order to crate a graph or tree among them for bridging or routing purpose, control plane protocols are used.… Read More »

Build Your Development or Lab Environment with Ravello Systems
When preparing for my Simplifying Application Workload Migration workshop (coming in webinar format in autumn) I tried to find a solution that would allow me to recreate existing enterprise virtual network infrastructure in a cloud environment. Soon I stumbled upon Ravello Systems, remembered hearing about them on a CloudCast.net podcast, and got in touch with them to figure out whether they could help me solve that challenge.
It turned you might use Ravello Systems’ solution to implement disaster recovery, but I got way more excited about the possibility to use their solution for labs or testing. To learn more about that, listen to Episode 32 of Software Gone Wild.
