Hey Bro, Do you even LISP?
So in the last article, we discussed a bit of why a solution like LISP ( Locator/Identifier Separation Protocol) is required. To summarize, there aren’t enough IPv4 addresses to go around and there are too many IPv6 addresses to let them ‘roam’ using traditional routing methods. Available in IOS (15.1X+) and NX-OS with standards currently being developed within the IETF LISP Working Group, LISP provides a promising solution to mapping IP nodes to locations on the Internet.
If you read the last article, by now some of you are saying, “John, the devices that roam, such as mobile phones, can simply acquire new addresses on the most local network. Why do we need LISP?” It is true this is how we do it now, and it works reasonably well for most users and applications. While it would be nice to seamlessly stream as we move from one network to another, that is more of a luxury feature than a necessity.
The Case for LISP
Let’s forget about mobile devices for just a moment and consider virtual machines and cloud computing. Virtual machines (VM) themselves are increasingly mobile. If I want to do maintenance on some bare metal, I can migrate that VM to another node but if my IP address is going to change, this adds a series of complications in updating services and applications such as DNS (Domain Name Service), to point at the correct address. These name to address mappings can be cached causing significant delays between a desired move and an actualized result when the cache finally expires. Read More »

Since returning from Cisco Live! I have been working on our next big project. In this case, I will need help in my design and deployment so I have to select the company that will help me; choosing a VAR (Value Added Reseller) for the project is a very important choice. Most companies have a policy of getting three or more SOWs (Statement of Work) from partners, but once they are in you are left with several very similar documents and the main difference is price. Anyone that has been in this industry for any amount of time knows choosing your partner purely based on price is a great way to set yourself up for failure.
So how do you choose a partner? Hopefully, you have taken your stack of SOWs and have whittled them down to a manageable number of potentials. Again, hopefully they all have similar levels of experience with the type of deployment you are looking for and possibly similar prices. One of the things I ask up front is if the company is a Cisco ATP (Advanced Technology Partner). If they are, then they stay in my possibilities stack, if they aren’t then even if they stay in the possible stack they have a long hill to climb in the selection process. A company being a Cisco VAR and an ATP means they have proven expertise in an area. They also have direct access to Cisco product resources beyond the normal TAC (Technical Assistance Center) path I would have to take in opening a case and seeking support. Read More »

Most everyone has heard the phrase, “There’s no such thing as a free lunch,” a phrase referencing the fact that everything has a cost and if you’re not paying for it, someone else is. In the US today, the largest age group in our population is comprised of Baby Boomers (people born between 1946 & 1964) and that group is putting a significant strain on our healthcare system just because of the number of people and median age in this category.
That strain, in combination with the current economic climate and Medicare’s general lack of resources has produced a recipe for disaster. If the government wishes to provide healthcare to a growing number of people with increasingly limited resources, the government will have to cut back on healthcare costs elsewhere, which will likely compromise the quality of healthcare offered and/or the number of people subsidized healthcare is offered to. This post isn’t meant to be a sob story – there are a ton of technologies, both current and in-development, capable of picking up some of the slack. The real question is, are we willing to pay the price?

“I confess that in 1901, I said to my brother Orville that man would not fly for fifty years . . . Ever since, I have distrusted myself and avoided all predictions.” — Wilbur Wright, 1908
In SDN in the Enterprise: aligning with business needs I highlighted one of what some people are claiming to be the most disruptive technologies in the networking space in recent memory: Software Defined Networking (SDN), or what I like to call the continuation of the abstraction of everything. Today we’ll explore some of the ways I believe SDN will and will not change networking.
Trying to predict the future in any endeavor is fraught with danger, or at least substantial risk of embarrassment. Winston Churchill once said, “I always avoid prophesying beforehand because it is much better to prophesy after the event has already taken place,” and he was on to something. Technology predictions, in particular, seem to have a funny way of getting away from even the most intelligent and business-savvy among us. Hit the target, and you look like a genius. Miss it, and if you have a high enough profile people will remember it forever. Worse than that, however, is that in business if you miss the target you leave money on the table, or in the worst cases sink the company. Read More »

“We (Real Madrid), with our experience & ideas on how to grow in the sports and entertainment world, and you (Cisco) with your technology, innovation and revenue models… our collaboration, has always resulted in a win- win relationship…and, a proven reference in the world” – Enrique Uriel, CIO, Real Madrid
Eight years ago we embarked on a relationship with Real Madrid to collaborate in transforming the Santiago Bernabeu stadium into the “Ultimate Bernabeu,” which would deliver a fan experience unlike any other. Our first goal was to build a network that would make the stadium the safest, and most secure in the world.
That goal was closely followed by the next phase, which was to support the need for more “things” being connected to the network in the stadium – broadcasting companies, sponsors, ticketing, hundreds of partners and VIP’s such as the Royal family! The most recent goal, embarked upon three years ago, was to address the continually evolving need for fans and members to connect with the Club through technology. Together we innovated, designed, and transformed the fan experience through key Cisco solutions – StadiumVision, Connected Stadium Wi-Fi , and StadiumVision Mobile – to enable the most interactive “live” experience in the world.
