Los Angeles Unified School District – iPads for Everyone!

September 18, 2013 at 3:11 pm PST

Earlier this year, Los Angeles Unified School District announced a $30 Million deal with Apple to distribute iPads to every single one of their estimated 650,000 students. This marks a milestone in public education as the first ever school district to deploy this kind of device to each and every student. Over the past several years there have been many pilots and test classes involving the oft-named ‘one to one’ approach to technology in the classroom; one device for each learner, however there has not been a rollout of this scale, childern using ipad

How does this shape the future of education for LAUSD students, and more importantly, how does this reflect on the evolution of the classroom for the 21st century student? Read More »

IoE: Dead or Alive on Wireless

September 12, 2013 at 2:51 am PST

When we examine the average wireless client on a network today, we see a few options. There is the smartphone, the tablet, or the laptop. Even the Apple TV and Roku are often based off of similar technology and chipsets. All of these devices connect to a wide range of services, often consuming large amounts of bandwidth: we stream music while we browse; we video chat with friends, family, and coworkers across the globe; catch up on our favorite shows or sports teams. Occasionally, we do all of these things at the same time.

Our current wireless networks are built to handle this type of traffic. With 802.11AC, it is clear that we will be ready for anything that our standard client will encounter in the near future.  But what happens when the standard client model is broken?  The increasing shift to an Internet of Everything (IoE) forces us to face this question about the future of wireless clients.

There are lots IoE devices already on the market, and the next couple of years will see developments not that dissimilar from those during the “internet revolution” of the late 90′s. Finally, the average user will have the access and the ability to afford the smart homes we have been dreaming of for the past thirty-plus years. Read More »

Solving the Network Location Problem with LISP Part 2

September 4, 2013 at 11:32 am PST

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 »

Choosing a Cisco Partner for an Advanced Technology Project

August 28, 2013 at 12:13 pm PST

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 npeople meetingumber 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 »

Is Affordable Healthcare Worth The Cost?

August 21, 2013 at 9:25 am PST

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?
