SDN and NFV Use Cases in EPN

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 start looking at some use cases where some of […]

SP360: SERVICE PROVIDER

Have Global IPv6 Deployments Really Slowed Down?

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 false. […]

Quitting the Legacy IP at Cisco Live Milan

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...

Moving to IPv6: Rebuilding the Heart of the Internet Without Missing a Beat

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 recognized industry expert on IP, […]

Demystifying IPv6

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 with all of the […]

Setting Up an IPv6 Testing Plan

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 about […]

Real World Demonstration of MAP for IPv6

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. […]

Enterprise Networks and the Drive for IPv6

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 fast forward only […]

Cisco Opens Up EIGRP

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 major attributes are: EIGRP does not mandate many network design […]
