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 hardware as traffic grows. Read More »
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 Mark McKillop, was the balance between showcasing the latest technology and maintaining the simplicity of the network. This year we had a mixed L2 + L3 core design. This design helped decrease the impact of various parts on each other. The L2 core was in place for the “special-case” requests, which a routing-based infrastructure could not help with. Read More »
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 Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:

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 »
