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 […]

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 […]

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: Assessing the network infrastructure, operating systems and applications in use Assembling a team to handle the integration […]

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 […]

By Steve Simlo, IPv6 Product Manager, Cisco Network Operating Systems Technology Group As IPv6 gains more and more ground within the Internet we are starting to see recognition amongst the wider community that technologies such as Carrier Grade NAT (CGNAT) have some significant drawbacks from a service and scalability standpoint. Some of the issues were […]

We first talked about the Mapping of Address and Port (MAP) method to handle IPv4 exhaust and the transition to IPv6 last week. MAP is based on two IETF drafts currently in the process of standardization in draft-ietf-softwire-map (MAP-E) and draft-ietf-softwire-map-t (MAP-T). The real advantage with MAP is that it’s stateless and doesn’t require additional […]

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 […]

The Internet of Everything fuels our daily lives, but leads to some new challenges in the networking space. Join us for this week’s episode of Engineers Unplugged as Damian Karlson (@sixfootdad) and Tom Hollingsworth (@networkingnerd) discuss the pros and cons of IPv6, firewalls, and the failure of 1970’s math. Watch and see: Welcome to Engineers […]
