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:

The World IPv6 MPLS / Ethernet / SDN World Congress events wrapped up recently with over 500 industry specialists in attendance, including myself. For 3 days the buzz was on how IPv6 has advanced since last year’s World IPv6 Launch to become reality.
Day One focused on Mobile, Day Two on Bring Your Own Device (BYOD), Home networking and emerging Cloud and Core applications of IPv6 and Day Three looked at Security and Measurements.
Here is my personal summary of a few of the items that I found most compelling:
1. Mobile IPv6 based deployments are happening now. Providers such as Verizon and T-Mobile are offering real services over LTE. In addition we are seeing some emerging niche services such as the “Advanced Emergency Response Service” in Slovenia being deployed to leverage some of the emerging advanced capabilities of IPv6 in terms of QoS, policing, marking and advanced unicast and multicast routing.

There are a number of ways to deal with IPv4 exhaust and IPv6 transition, including Carrier Grade NAT and stateful Dual Stack Lite. Cisco has added another method called Mapping of Address and Port (MAP) 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 hardware as traffic grows. In fact, the MAP implementation on the Cisco ASR 1000 or ASR 9000 is just a software feature that can be enabled as needed. Read More »

Cisco Live Orlando, June 23-27, 2013, is quickly approaching and registration is open. The Security track this year includes 72 breakout sessions, 74 hours of labs and seminars, and 3 Product Solution Overview sessions, accounting for about 15 percent of all the content delivered at Cisco Live. New for this year we will have several talks aimed at the network engineer in the role of a data analyst, helping them to better utilize and understand the data that comes from their networks (BRKSEC-2001, BRKSEC-2006, BRKSEC-2011, BRKSEC-2062, BRKSEC-3031, and BRKSEC-3062).

T-Mobile USA has been one of the first carriers to widely deploy IPv6, seeking to overcome the lack of IPv4 addresses and to lay the foundation for their network for the Internet of Everything. However, one of the headaches they’ve faced is that some applications which work fine over IPv4 don’t play nicely with IPv6. That’s a real challenge for service providers, impacting their ability to migrate completely away from IPv4 and complicating their network operations.
