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 »

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.

We’ve been actively promoting the adoption of IPv6 at various venues -- back in January at Cisco Live London, and a few weeks ago at the V6 World Congress, which focused on the adoption of IPv6 in mobile networks.

Our next big venue is Cisco Live in Orlando, Florida June 23-27, 2013 and I want to take the opportunity to reflect on how IPv6 is becoming an increasingly important component of the event agenda, infrastructure and look forward to some of our future ideas for Orlando.

I have personally participated in Cisco Live for over 15 years as a speaker but this was my first time as a member of the IPv6 Team. For those of you who do now know I am the Product Manager for IPv6 in Cisco’s Core Technology team that we call Network Operating Systems Technology Group.

My observations on what I saw and heard in London were as follows: Read More »

For those of you familiar with the movie “This is Spinal Tap” the volume on SDN has been turned up to 11 for some time. However, too much of the sound is around the technology and not on the benefits to network operators. In fact, Cisco views SDN technology and our Open Network Environment (ONE) as an opportunity for service providers to monetize and optimize their existing assets. In other words – leverage existing investments as much as possible and build SDN and programmatic Cisco ONE capabilities on top of them. Read More »

Cloud adoption is accelerating at an impressive pace. To gain a deeper understanding of the current rate of change, and the dynamics of cloud’s evolution, the Cisco Internet Business Solutions Group (IBSG) engaged with wide-ranging groups of IT executives and decision makers—first in 2010, and then again in 2012. Our in-depth interviews focused on five industry verticals: government, manufacturing, financial services, professional services, and retail.

In our interviews, we encountered many examples of cloud implementation projects, which we call “adoption dynamics,” because they are nearly always part of the enterprise cloud adoption process. While there is no prescribed order, enterprises often begin with smaller, well-defined projects that fall into six categories:

1. Consolidation of IT resources into cloud-based architectures for true cloud transformation
2. Next-generation workspace
3. Simple back-office business processes
4. Software development
5. Agile and scalable web presence
6. Transformation of computer grids and analytics

Today: Different Industry Verticals Share Common Adoption Dynamics
