Setting Up an IPv6 Testing Plan

May 28, 2013 at 1:30 pm PST

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 IPv6, but we could just as easily be talking about virtualization or BYOD.

So now that we have the lab build up in progress, what’s next?  Read More »

Summary: Securing the Internet of Everything: An Introduction

I recently kicked off a series about security and the Internet of Everything, a pivotal topic that starts with the roots of IoE, IoT and M2M, which I explore in more depth in the first post.

Machine-to-Machine connections make up a huge portion of the Internet of Things, both general concepts for the network infrastructures that link physical and virtual objects. These abstractions come together on IoE, making it possible for devices to orchestrate and manage the world we live in, as they become connected entities themselves.

But to fully discuss security on the Internet of Everything, we must first go back to the roots of IoE itself. The technology innovations that employ M2M and IoT were actually spun off from military and industrial supply chain applications. As IP became a more common communication protocol, IoT gained more traction, helped even more by the creation of IPv6 and other advancements in wireless technology. As ever-increasing data is captured and distributed on these networks, more intelligence is generated.

Read my full “Securing the Internet of Everything: An Introduction” blog post to learn more about this embedded intelligence that is a core architectural component of IoT, and how it informs the security for the Internet of Everything itself. And stay tuned! I have more for you to come in this series, including a look into IoE security framework.

Setting up an IPv6 Lab

May 20, 2013 at 4:31 am PST

I’ve blogged (a lot) about planning for the integration of IPv6 into your network, and I even threw in some thoughts about how to go about doing the integration.  Some of the procedures discussed in earlier posts included:

Equally important is the task of setting up a lab and (in our next post) developing a test plan. Read More »

Securing the Internet of Everything: An Introduction

Towards developing a Secure Architecture for the Internet of Everything, I plan to kick off a series of blogs around this pivotal topic.

In discussing security and the Internet of Everything, the first question that comes to mind is, “Which segment of “everything” is one referring to?”. A reasonable approach has been to understand the common attributes that crosses vertical segments such as Intelligent Transportation, Smart Utilities, Industrial Automation and so on. The Internet of Things (IoT) and Machine-to-Machine (M2M) are general abstractions for the network infrastructure that links physical and virtual objects. In Cisco, we now refer to these abstractions as the Internet of Everything, IoE. The IoE describes a world where billions of objects have sensors to detect, measure and assess their status; all connected over public or private networks using standard and proprietary protocols.

Until a point in time around 2008/2009, there were more human beings in the world than devices connected to the Internet. That is no longer the case.  Read More »

Real World Demonstration of MAP for IPv6

andrewyourtchenkoBy 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. EANTC (European Advanced Network Testing Center) interoperability testing gave me such a chance. The bulk of the work happened on EANTC premises in Germany this past February. The overall activity involved many representatives from various vendors making their devices talk to each other. The goal is to test the protocols in several areas, including MPLS, SDN, and IPv6, but the highlight for me was the testing of MAP (Mapping Address and Port) -- a new protocol to enable the sharing of IPv4 addresses by several customer premise devices without keeping the state at the service provider end.

This protocol is being developed by IETF, and has two flavours, the standards-track “MAP” which uses encapsulation to transmit the packets, otherwise known also as MAP, and the experimental track “MAP-T” -- which uses the address family translation in order to send packets, instead of the encapsulation.
