Welcome to our government blog! I hope you will become an active participant and visitor to this community. Each week, we will explore various topics that are top of mind in government. I encourage you to share, comment, and probe so that we can have genuine discussions about what is happening in this ever-changing industry.
The experts on our team, who bring together decades of experience in advanced technologies and government know-how, will be blogging about cloud, cybersecurity, security, teleworking, innovations in government , and much more. If you have a topic of interest related to government and technology that you would like to discuss, please comment on this post. We’d love to hear from you!
Yesterday partners got to enjoy lively music during the General Session, but today, it was all about magic…and the cloud. Technology magician Marco Tempest treated partners to magic tricks using lights and a display, and he was followed onto the stage by Michael Capellas, CEO of VCE, and Padmasree Warrior, Cisco’s CTO. The theme was how to impact innovation, and both Michael and Padma highlighted the Cisco technologies that can help partners to differentiate.
Michael kicked off his talk with the statement that “cloud is not marketing hype,” but in fact will be a foundational part of the IT industry for the next three to five years. Michael sprinkled interesting facts throughout his presentation—for instance, did you know that 200 million users connect to Facebook via mobile devices? Or that 60 billion instant messages are sent per day? According to Michael, stats like those demonstrate that the consumer has already adopted the cloud, and it will spread into the enterprise.
This will open up a whole new world of possibilities for partners, as the world of applications that will be accessed by lots of different devices will change. Businesses will need new applications, location-based applets, new forms of integration, analytics and behavioral analysis, new development networks, development clouds, and software as a service. And all of those will be supported by the cloud. Michael concluded his presentation with his “Fearless Forecasts.” Watch out, partners: There will be a $50 billion converged infrastructure market in three years, and private cloud will lead enterprise and public sector opportunities.

I’m really excited by this new Cisco and Librestream MMVC solution. Lots of information out on the web, and lots of questions so I thought I’d put a brief video together to give you an introduction and to see if we can get a discussion going and also to see if we can answer some of the questions for you. The video starts talking about what really matters. What are the pain-points that manufacturers and industry have today? How do they get hold of the right people to fix things if something goes wrong, and how can they say ‘I see what you mean now’ -- and really mean it?
All this matters because keeping things running matters. Being able to communicate effectively in real time using video, speech and pictures -- globally, if need be -- matters. Knowing what’s going on and having clearer visibility matters. Working out what to do next, whether it’s developing a new product or fixing an operational problem fast, matters a lot.
In the previous installment of our series of IPv6 posts, we covered some common myths regarding IPv6. In this post, we’ll talk about how the role of ICMP has changed in IPv6 compared to IPv4.
In IPv4, ICMP provides error reporting, flow control and first-hop gateway redirection. This functionality, which is also available in IPv6, is usually not essential to the operation of your network. With IPv6, however, ICMP has gained a much more significant and essential role because of new functionality that is now performed through ICMP. Fragmentation, Neighbor Discovery, and StateLess Address AutoConfiguration (SLAAC) represent essential functionality which is now performed using ICMP messages. Furthermore, many ICMP messages are designed to be sent to multicast addresses instead of only unicast addresses. Therefore, ICMP in IPv6 gains a whole new importance along with a new set of security concerns.
Last post I covered some of the basics around VM networking. But, as we all know, there is more to networking than just packet transport. One of the biggest challenges with VM networking is security policy enforcement. The fundamental nature of server virtualization introduces a new set of challenges for both network and security admin to ensure proper compliance with infosec policy because of things like VM mobility, VM sprawl and potential loss of transparency. With the introduction of the Nexus 1000V we gave network and security admins many of the security tools they were already familiar with with physical Cisco switches--this should not be a surprise, since the Nexus 1000V is a full NX-OS switch. Last summer, we built upon this functionality with the Virtual Security Gateway. This zone based firewall was specifically desinged to meet the unique challenges of VM environments.
