My last post reviewed some of the building blocks of SDN (Software Defined Networking) and positioned the protocols and APIs (Application Programming Interface) into categories so that the multitude of technologies associated with SDN can be positioned in a coherent framework. This month I’d like to…

For those that are not closely involved with IPv6, it may seem like the emphasis on migration to the new addressing scheme is waning. But while the hue and cry over IPv6 may appear to have quieted down to a background noise since 2010-2011; a closer inspection would prove that perception to be quite…

It’s that time of the year again – time for some computer and human networking at Cisco Live Milan! This year I’m taking the unusual and somewhat risky step of blogging about the network infrastructure before the event. This is because we’re going to try something interesting for the networkin…

Within the coming decade, Internet Protocol version 6 (IPv6) will be key to enabling 50 billion connections among people, processes, data, and things in the Internet of Everything (IoE). But how we get there from here is not a simple matter. I’m very pleased to invite Mark Townsley, Cisco Fellow and…

Version 6 of the Internet protocol (IPv6) is a key enabler of the Internet of Everything (IoE). People, data, and things all need IP addresses to connect to the Internet. But we’ve already run out of IP addresses under IPv4, which dictates almost all (98.5 percent) of Internet traffic today. Even wi…

In my previous blog, I talked about building out a lab to help with IPv6 integration testing.  It cannot be understated how important it is to test any new feature that is going to be deployed on the network.  This statement is true independent of the feature involved.  In this case, we are talking…

By Andrew Yourtchenko, Technical Leader, Network Operations Systems Technology Group As any geek, I find it a lot of fun to get some hands with the new technology – be it a new gadget, new product or a solution. It’s not very often that I have a chance to play with a whole new protocol.…

It was not that long ago that whenever I read an article about IPv6, it usually discussed how the IPv4 Address depletion in other countries. At that time, the adoption of IPv6 was coming from other countries that where the v4 address space was depleted, the US Government, or Service Provider. Well f…

What’s new and exciting with EIGRP (Enhanced Interior Gateway Routing Protocol)? Actually, lots…  First a bit a background on EIGRP. EIGRP is an advanced distance vector routing protocol used extensively by enterprise customers.  It is very popular because it is simple to deploy and support. Some ma…
