In my last blog, I talked about the new 15 IOS code and discussed the reason why they jumped from 12 to 15 in their code—well, my theory of why they did anyway. I also started a discussion about the new licensing they will be using, plus, their newest Integrated Services Routers Generation 2 (ISR G2). But right now, the types of licenses that Cisco will be providing with their new routers are what I really want to focus on.

Types of Licenses

First and foremost, how does this change what you need to buy? Answer… That depends on exactly what you need from the router. And to answer that question at all, you just really need to know about the types of licenses that will be available regarding them.

Okay, Licenses are first categorized by their time frame, or how long they are good for.  Check out the following figure—the time frame is either specified as permanent or temporary as shown by the top green boxes:

Permanent Licenses

Just as you would think, a Permanent license is good for the life of the device on which it is installed.

Temporary Licenses

A Temporary license can be used for evaluating new capabilities or an emergency situation. A temporary license allows a feature set to be used for 60 days of actual usage. When the 60-day period expires, the device will continue to operate normally until reloaded. After the reload, the device will default to the original functionality before the temporary license was enabled. Only the actual time that the temporary license is enabled counts towards that 60-day limit. The Cisco Technical Assistance Center (TAC) can provide an extension license for longer trials or other circumstances. Or, you could opt to just never reboot your router, and you’re golden!

Technology Package License

A technology package license is similar to the current image and licensing types that you are used to (i.e. advanced IP services, advanced security, etc.). however, instead of the many types that you have now, there are now just four:

• IPBase – basic entry functions
• DATA – includes MPLS, ATM, Multi-protocols, IBM support
• UC – unified communications, VoIP, IP Telephony
• SEC – security, IOS Firewall, IPS, IPSEC, 3DES, VPN

Software Licensing Framework

Alright, last thing before we tie this post off. We mentioned the Cisco Licensing Framework and Cisco Software Activation. This is the primary control part of this whole scheme to “help the customer track hardware, software, add services, upgrade images, and transfer licenses easier”. Oh, and it ensures that Cisco gets paid for every little thing too.

So let’s go through the whole process here. You go out and by a new ISR G2 router, it works the same way if you own one already and are buying new features as well. Ok, so you have it or buy it, first thing you get with the purchase is a Product Authorization Key (PAK). The PAK is an 11 digit alphanumeric key.

With the PAK you access the Cisco Licensing Portal, www.cisco.com/go/license and provide the PAK, serial number, and Product ID of the device. hA license file will then be generated for that specific device and that device only. You can download the file or have it emailed to you. Finally, you have to install the license file onto the router. This is much more complicated and time consuming than anything we’ve ever had to do before. However… Cisco doesn’t want to discourage you and make you complain….

So, to further “help” you in keeping track of all this licensing and to make it easier for you download and install the licenses. Cisco has made a handy application that you can install on a management workstation. This program is called Cisco License Manager (CLM). It is does some similar discovery functions and operates a lot like the Cisco Configuration Assistant (CCA).

Cisco’s 12.x code has definitely proven to be a very stable operating system. But since change is a given, Cisco has gone through a lot of revisions, and it’s finally time to morph into the 13.x code. But no… wait! 13 is bad. Buildings don’t have a 13th floor, and even if they do, elevators don’t go there! 13 is a superstitiously cursed, unlucky number here in the U.S.

Friday the 13th has been cursed since the 16th Century because that’s the day that the King of France attacked and attempted to jail all of the members of the secretive society, the Knights Templar. Reading folklore tells us that a vast fortune disappeared at that time too, and no, the Masons didn’t bring it to the U.S. nor did Nicolas Cage find it a couple years ago.

Yet, strangely enough, the also secretive and private Swiss banking system began around the same time all this vast fortune from the Knights Templar disappeared. Okay, so I’m not a historian, I’m a Cisco networking guy, so I really don’t how much truth there is to any of this, (if any), but it’s sure some sweet fodder for great stories and movies.

Cisco appears to feel a bit superstitious too… they skipped the 13.x code and went to… 14.x code? Nope. Not 14 either, because 14 happens to be a really nasty number in parts of Asia. So to keep anyone from getting the willies, Cisco’s jumped to the new 15.x code! The actual reason for skipping versions 13 & 14 code is of course, nothing but a rumor, but it it’s a fun way to start to this blog. And just as with secret societies and bank accounts, no one’s talking!

(more…)

Alright, let me make sure everyone knows this fact straight away: No matter how lofty your personal goals may be, the first hurdle we’ve all got to jump on our way to networking stardom is to conquer the all-important Cisco® CCNA test and get that certification. And all should agree that this must be achieved prior to talking the other professional level certifications, like CCNP, CCNP Wireless, CCSP and CCVP. But is it really? Is it actually the gatekeeper it’s believed to be?

It is true that the CCNA exam is a notoriously difficult test that can present a serious road block for some, but once you’ve nailed it, you can then get to work collecting all those other valuable certifications. And of course, we all know that Cisco certifications are the industry standard for networking professionals, but don’t you just sometimes wonder what Cisco is actually up to when it comes to all those different certification tracks? I know I do!

I blogged regarding the CCNA Concentrations (CCNA Wireless, Security & Voice) in an earlier post, and most of that information is still definitely valid, however, there have been some slight changes that I need to tell you about to clarify some increasingly common misconceptions. I get asked questions about this subject nearly every day, so here’s your intel…
(more…)

If you’ve been paying attention to what the latest must have certs from the Cisco world are, then you’ve definitely heard about the happening new CCNP Wireless track. If you haven’t, no worries, I’ll get you up to speed right here: The latest, greatest professional level cert is the CCNP Wireless Certification that sits squarely between the almost as recently announced CCNA and CCIE Wireless Certs. (Why it isn’t called the CCWP is presently beyond me, but I promise to fill you in as soon as I find out. I mean, that’s what I’d call it, wouldn’t you?)

Anyway, so you know, the CCNP was just unveiled this June, but the exams won’t be available until late July 2009. This means that if you’re skill-set is already pretty solid, it would be a really good idea to get yourself on Cisco’s wireless certification path ASAP to keep your edge. For those of you that currently may not be as high up on the I.T. food chain as you’d like, this freshly-minted wireless certification trio is exactly what you need to get you to the top!

The new Cisco Wireless career path looks something like this:

Although there are no laws against aiming way high and going straight for the CCIE Wireless exam, know that there still isn’t, (as of this writing), a single person who’s come close to succeeding at that.

Why? Well, the CCNA Wireless course and exam combine to present an unusually tough challenge as a first step certification, and the next step — the CCNP Wireless Cert — is so packed full of leading edge technologies, passing the exams is a nicely notable achievement in itself.

These factors make going for the gold and hitting the legendary and formidable CCIE Wireless course/related exam without getting your CCNA and CCNP Wireless certs first, is about as wise as attempting to ace the MCAT and get into med school in 6th grade.

Just because you can take these exams doesn’t mean you should, because doing so without the proper preparation and knowledge is basically a great way to waste your hard earned dollars. These exams are hard enough when you’re armed with the knowledge that you’ll lock in during the class, so don’t waste cash by skipping these vital prerequisites! After all, this is a big reason why the CCNP Wireless was introduced in the first place—to bridge the knowledge gap and increase your odds of success in attaining the ultimate— your CCIE Wireless Certification!

Okay, so here’s a preview of some of the technologies covered within this new CCNP Wireless track: (to see the exam objectives and course outline for the CCNA Wireless, click here)
The CCNP Wireless is made up of four more modules taken after the CCNA Wireless. They look like this:

Lastly, here’s a brief description of each of these courses and what they cover:

• Implementing Cisco Unified Wireless Mobility Services (IUWMS) v1.0
  The IUWMS course is designed to give students a firm understanding of how to integrate mobility services into the network as well as tune and troubleshoot the WLAN and implement indoor enterprise mesh networks. Plus you get to play with the very new Mobility Service Engine (MSE) devices.
• Implementing Cisco Unified Wireless Voice Networks (IUWVN) v1.0
  The IUWVN course is designed to give students a firm understanding of how to integrate VoWLAN services into the WLAN and be able to implement VoWLAN, QoS, and high-bandwidth applications into the wireless network.
• Conducting Cisco Unified Wireless Site Survey (CUWSS) v1.0
  The goal of the course is to provide students with information and practice activities to prepare students to technically plan and conduct a wireless site survey. The student should be able to design the RF network and conduct a post installation assessment to ensure compliancy.
• Implementing Advanced Cisco Unified Wireless Security (IAUWS) v1.0
  The goal of the course is to provide network professional with information to prepare them to secure the wireless network from security threats via appropriate security policies and best practices, as well as ensure the proper implementation of security standards and proper configuration of security components such as ACS and NAC.

Note: While there is no exact order you must complete the courses or exams, I highly recommend taking and completing the Site Survey course as a first step. This course/exam provides the material best suited after the CCNA Wireless course/exam and will ensure you have a sure-footed foundation for the other three courses/exams needed to achieve the highly desired CCNP Wireless.

There you have it! The four courses needed for the CCNP Wireless certification. As I already mentioned, the exams for each of these courses will be available in September.

I am teaching a CCNA Wireless class in Dallas soon. Hope to see you there!

The year to focus on winning the battle, not the war!
I’m not saying to give up on big dreams–no way…We need those to keep us motivated! I’m just saying that grasping every opportunity— however small— will be an important key to success this year. Yes, we all know the media can hype things now and then because freaking us out is really good for ratings, but it’s not exactly breaking news that our country/the world is undergoing a pretty challenging period fraught with an unprecedented type of financial debacle that has, and will likely affect all of us. Possibly, dramatically!

But we can’t just respond by shrinking in fear and curling up in a ball. Instead, this is a time for taking action and facing our problems directly. Rethinking our priorities and remapping our life-strategy is critical now, and by overcoming each obstacle— each battle— we can and will ultimately succeed and win our personal wars. For many, one very important battle to win relates to that hugely important asset known as our job. We need to take some serious strategic action to protect this and secure our professional well being. In a world where speculation seems to be everywhere, I can assure you that one very wise, safe and sound place to invest is in furthering you and your career!

That’s because if we focus on bettering ourselves during these challenging times, we’ll be poised and ready to score the best top-drawer positions that will inevitably become available when— even as, things begin to turn around. History tells us that most often the best times follow the worst, and this means that making the right moves during hard times can and most likely will result in greater rewards than you’ve dared to even dream of later!

So, how can you best ensure that you keep your job and income, find a new one— maybe even a better one? Take a moment to envision the end of 2009 and how you will get there.

I’d say to stick to the fundamentals and take a conservative, long range approach toward your career by acquiring some solid training and adding to your present skill-set. For me, I have my sights on more training and the CCIE Wireless certification.

Each merit, capability and talent you can gain is a battle won in the ultimate goal of winning your war over lost or reduced income and/or employment! By arming yourself this way, you will be able to get a job, keep or significantly advance your current position. You may even become flexibly equipped to change careers and re-enter the workforce in a more dynamic, lucrative sector. The key is to concentrate like a winning racehorse that unwaveringly looks forward toward the goal without getting distracted by the thundering hooves of negative chatter and influences. Stay motivated, stay in training, and stay focused on the prize!

Another way to look at this process is like going for a base hit in a baseball game. After all, four of these make a run, and a few more of them added up together can win the game. What I’m saying is that something that looks like a small opportunity, like a base hit, can lead to a big win— a job, advancement–even a shiny, new career! You really can win in 2009, but to do so, you’ve got to stay motivated and forget about that home run – that’s so 2005! Instead, turn off the T.V. search for, find, and apply yourself to the one, most promising opportunity you have today— it’s there. It may be just a base hit, but it very well could lead to getting you some serious game. As one opportunity evolves into another, you’ll gain momentum, and even more importantly, fulfillment and increased motivation— things that are much more powerful than influence and money. And ironically, you can’t possess either influence or a sustainable income without being motivated!

One opportunity you have in front of you today is GlobalNet Training— a source of the kind of powerful knowledge that can equip you with everything you’ll need to succeed in the prosperous and ever-growing field of I.T. Except for attitude— that part is up to you. However discouraged you may currently be, it’s got to be you that chooses action, empowerment, and success over defeat and ruin. GlobalNet Training meets the full range of I.T. training certification needs— all the way from Introduction to Networking, to Cisco and Microsoft Certification, Security, and my personal favorite, Wireless networking. Armed and equipped with solid, certified skill-sets like those we offer, even the world of 2009 and beyond can truly be your oyster!

So, let’s get some major game going, get motivated, trained and ready to build our best lives beginning now in 2009— one base hit gained, and one battle won at a time!

All the Best!

It’s not exactly breaking news that so many of us are either struggling to keep our current jobs, or battling with intensifying competition to secure a new one. And as this recession deepens, contending with trials of keeping and/or finding a good job are only certain to intensify.

Not so long ago, as long as you behaved well, showed up for work reliably, and did what was expected of you, your job security probably wasn’t anywhere near the top of your list of concerns. But those days are unfortunately gone— people now need to do more than just the basics to ensure and sustain their employability. In this present climate, you need to stand out and stay ahead of the ever increasing pack of candidates that are vying for any and all available positions. This has always been a good idea in the quickly evolving networking field, but now, it has become a vital necessity!

In I.T., one  great way to really shine and prove just how valuable you are is to earn certifications. I’ve heard so many stories of people with certifications beating out rivals with years of experience on them for the very reason that they were certified and their competitor wasn’t. I’ve even hired people because of this reason alone myself!

However, I do have to say that holding just any old network cert won’t get you where you want to be. Just as a holding degree from an institution like Yale tends to be a lot more impressive than having one from some no-name academy, getting your certification from some brain dump just won’t gain the innate respect and validate your worth to a potential employer like being certified by a well-reputed, authorized, industry standard training facility will.

You can be successful! Let me help you find your path.

You can contact me on my forum or through my training company at www.globalnettraining.com.

Cisco just announced new certifications in the market and they’re super exciting! Of course, a lot of you are already writing me about when my books will be out… All I can say is I’m pounding the keyboard as fast as I can and that yes, I wish I could figure out some way to do that while sleeping too! But since I haven’t figured out how to do that yet, just hang in there-at least I’m not on strike!

Anyway, I actually want to talk to you a bit about the old network certification path first, starting with the CompTIA certifications that led to the CCNA. Referring to the figure below, a newbie to the networking field would start off by studying, learning, practicing on LANs and probably some hosts and servers as well. After that, they’d possibly take the CompTIA Network+, Security+, Server+, A+, etc:

Moving right along, with the foundational background of the CompTIA certifications in hand, our newbie’s next logical move would be to dive straight into the Cisco CCNA — either through the Certified Entry Network Technician (CCENT) or by just taking the CCNA exam (640-802). Of course, all this assumes that the Newbie has made a career choice and opted for the “Networking” path.  Makes sense…

Once you’ve nailed your CCNA, you’re good to go for the professional level certifications like, Cisco Certified Network Professional (CCNP), Cisco Certified Security Professional (CCSP) or Cisco Certified Voice Professional) (CCVP) as shown here in the next figure:

But let’s say you still want more. At this point, all paths lead to the veritable PH.D. of Cisco Certs-the Cisco Certified Internetworking Engineer (CCIE). People really don’t have to subject themselves to the special torture of the lower level certification process CCIE gauntlet, but getting through it alive and well definitely has benefits. (At the very least, you get major props and bragging rights!)And, although many people have tried many paths (many times), the most popular way to tackle this monster is step by step: CCNA, CCNP, then the CCIE Routing and Switching (R&S) lab. Over 50% of the pushes for the CCIE summit take this route!

But as I said, Cisco has tweaked things and changed its various professional paths to networking nirvana. Yep…Cisco even put a new one on the radar — it’s all pretty cool!

For instance, if you were going with the foundational CompTIA certifications, you can still take:

1. Your basic CCENT/CCNA Routing and Switching Cisco foundational certifications.
2. The CCNA, CCNA Security, then the CCSP, and finally the CCIE Security.
3. The CCNA, CCNA Voice, the CCVP, then the CCIE Voice.
4. The new, most exciting one of these is the new CCNA Wireless Certification path. Start with your CompTIA foundation, grab your CCNA, and then head straight for the CCNA wireless. In the near future you’ll go to the Cisco Certified Wireless Professional (CCWP) and then on to the CCIE Wireless.

Cisco has my full attention here — are you with me?

(Note: The basic CCNA, either through the two test method of ICND1 or ICND2, or the one test method of the 640-802 exam, is a requirement before any other CCNA certifications.)

Let me show you what Cisco’s new approach to certification looks like:

Okay-you can see that yes, it’s true, there are now four paths, and you get to choose any of them from beginning to end-sweet! (Again, the advanced Wireless certs are not announced yet – hopefully soon.)

So which path is for you? Since they’re all awesome, I’d say, “take them all!” But that’s just me. I bleed Cisco blood, what can I say? Seriously, you really can’t go wrong with any of them, which is why the changes Cisco has made are so exciting. So many options — so many ways to succeed!

Oh, and just so you know, I’m going to be teaching all of these new courses soon at GlobalNet Training, inc, in Dallas, Texas-the exclusive reseller of my “Cisco Authorized Todd Lammle BootCamps” *.

Cheers!

*All courses are delivered by Internetworking Training, inc. a Sponsored Organization of FastLane.

Cisco has just announced that the CCNA 640-802 exam price is now $250, effective immediately!

Like getting the CCNA isn’t hard enough, now if you fail it, the cost, both financially and emotionally is a huge toll!

Well, let’s just make sure we pass our exams the first time….

Cheers!

Okay, Yes… The rumors abound suggesting our great Internet, as we know it today, is going the way of the Dodo. We could get on that boat and talk about the end of the Mayan calendar and the Nostradamus’s predictions too, or we can take a more sober approach and look at this issue not hysterically, but in an informed and logical way!

First, I’ll acknowledge the threat is real. Certain large corporations would love to become even larger and not only control our Internet access, but charge us for that “service” in the name of protecting our children from danger and impropriety and saving us adults from viruses and identity theft. Can’t happen you say? I’m telling you it can… Check out this little beauty that was, well, leaked from a supposed large, well, known marketing company about a month ago and is now making its way around the still free Internet (click the image to get the full-sized version):

As an analogy, think about way back when T.V. was free, and there was nothing you bought with that TV except, maybe an antenna. There were only a few channels on the air, though as time went on, more became available—for free. Now I pay somewhere around $130 a month now for HDTVs with satellite connections and a package of about 500 channels. Times have indeed changed… This was unfathomable 20, maybe even 10 years ago, and if I’m not mistaken, coming right up in 2009, there will be no longer be any free TV (analog signals) at all!

So what does this have to do with the Internet? A lot…Most people were getting onto the Internet in the mid 90’s, with many more going online into the late 90’s. Some people still weren’t on the Internet until the 2000s or so, but now, pretty much everyone is. Many of us absolutely need to be online simply to work. How did that happen? Well, let’s look at how this all progressed… First we paid the telephone co. for dial up, and then moved up to some broadband provider, and then, hmmmm… Now you can get one company to provide phone, video and data services…aha! Now we’re talking. Can you see where I’m going with this?

So, yes, theoretically, your Internet access could become controlled by your ISP and /or large corporations selling access packages at different levels/plans depending on your need/desire for access to get to various sites. But it may not turn out that we’re all doomed to this ugly fate. I’ll back the fact that the issue of preserving Net Neutrality is very real, but know that it’s has own league of Big Business behind preserving it! Google, for one, is developing free tools to enable big cable company’s customers to detect when their connections have been throttled, or when their access has been modified in any way. I’ll provide a link to an article detailing all this that came out June 15th in a bit, but for now, to quell your fears I want you to know that there’s a ton of effort happening right now to get laws passed that will block cable companies from this kind of censorship.

The F.C.C. itself has promised to take a serious look into charges that big-time cable and other large companies are planning to attempt an access heist on us. The article also mentions that in May there was a bill re-introduced to Congress asking to redraft the present U.S. Antitrust laws with language that would prevent network operators such as Comcast and AT&T from, I quote, “blocking, impairing, or discriminating against “lawful” Internet content, applications and services, or from charging extra fees for “prioritization or enhanced quality of service.” End quote.

So while plans for an access controlled, “pay per view” Internet may well be being laid, and the threat against Net Neutrality is definitely genuine, to me there’s a distinct possibility—even probability—that Net Neutrality will come out the winner! Check out the links below to the articles I mentioned and quoted and let me know what you think:

Google prepping broadband-monitoring tools
FCC: We’ll investigate Comcast-BitTorrent flap
Democrats revive another Net neutrality proposal

Repeat after me: “IPv6 is my friend”! And keep that up because it´s true! But I´m not going to formally introduce you to all its benefits just yet because going there would turn this blog into a full-fledged article. I´ll be going there really soon though, so stay tuned! For now, just know that IPv6 will be a hugely important part of your future, and let me continue my rave on why using Vista and Server 2008 are going to do great things for your networking career.

In my last post I discussed chimney and receive side scaling—stuff that new multiple processor servers are likely to come with. So now I want to move on to telling you about how the new stack provides optimization on both the receiving and sending sides for the hosts on your network. I´ll finish up by telling you why on earth all this Microsoft stuff I´ve been chattering about in these two posts is so very strangely important to you as a Cisco network admin! Here´s a couple good reasons:

Receive Window Auto-Tuning and Compound TCP (CTCP).

??????
• Receive window auto tuning optimized receiver-side throughput and upgrades the old TCP Windowing we used for receive flow control. This little beauty will allow us to have very large MTU´s.
• CTCP optimizes sender-side throughput and is most noticeable in high-latency, long round-trip time (RTT) networks (like wireless and cellular, or inter-continental links).

Receive Window Auto Tuning is enabled by default on both Vista and Server 2008 and CTCP is only enabled on Server 2008. Personally, at least right now, I see no reason not to enable CTCP on all your hosts, but Microsoft doesn´t advise doing this for some as yet unknown reason.

Okay, before I get to describing the good news part of all this Microsoft stuff, I need to explain something first: Receive Window Auto Tuning tries to send so much data so quickly that you can often watch network problems pop up as fast as noxious weeds. We´ve all heard multitudes howling about Vista creating wide variety of evils, so I´m pretty sure we´ll hear even more complaints as Server 2008 rolls out. But the thing is, it´s actually not Vista´s fault, or even Server 2008´s fault. Nope—it´s your fault! Why? Simple… You need to upgrade your network. This is the part I love about Vista and Server 2008, and it´s also the reason I´m writing a blog about Microsoft on my Cisco training web site! I see this as a true opportunity and so should you—an opportunity to get certified in these things so you will be poised, ready and able to cure the broken networks epidemic we´re about to experience!

Say you´re not surprisingly having problems with your network going up/down, application unreliability, on-line storage problems, and other disturbingly weird issues after you installed Vista. Steel your nerves and resist the temptation to revert back to XP—it´s not your solution. Yes, you can temporarily disable receive window auto tuning, but remember, if you do this, you´re pretty much satisfied with saying “I have a network issue that I can solve temporarily by disabling receive window auto tuning—viola!” You don´t want to do this permanently because it´s total denial, (which is unhealthy), and worse, it prevents you from accessing and enjoying all the bennies that new networking stack has waiting for you! Instead, roll up your sleeves, toss out the crate of tissues and: Upgrade your network to gigabit links for your hosts and switch ports as well as all your router interfaces add ten gig links and TOE cards with RSS capability for your servers, then watch your network rock the house! Oh, and don´t forget to take a (gracious) bow and accept that promotion! The new networking stack can optimally make use of all this bandwidth wealth. The older stack just didn´t have what it takes—it just was not smart enough to understand how to take advantage of it. Interestingly, this means bottlenecks will no longer clog at our hosts and servers, but on our network interfaces and routers instead.

I was in the U.K. last week and came across some fascinating facts: I read that there simply are “not enough certified network individuals with enough network experience and so, it´s estimated that by 2012, the Internet in the U.K. cannot exist as it currently does. For the U.S. that time frame is only slightly extended to 2015”. So basically, in order to keep enjoying our precious internet, we have no choice but to fully embrace the new networking stack and we need to get our networks upgraded, and do so ASAP! Sure, you can disable most of the features to make your networks work temporarily, but call me odd—is it really a solution if it means losing a proven 40 to 400% increase in throughput on your network when with a just few adjustments you´re good to go with the new networking stack instead? Do you really think that you can force your company to stay with XP forever? Sheesh… I remember many companies telling me that they would never consider using wireless networks! HA! That´s laughable today, although sure, I do know some super-high security networks that still don´t allow wireless, but can you imagine a network that exists completely without it? Probably not—at least very rarely and they´re definitely not the norm. In 5 years, it´ll be the same situation regarding IPv6 and Windows 7, due out in 2010 (which means 2011).

So to sum things up, take my advice and make sure you understand how to configure a Cisco router and switch, how to upgrade your network ports to gigabit, and how to implement TOE boards with receive side scaling support on your servers. Get Cisco certified and start planning this migration/network upgrade now; it could save your job!

Oh… Just this one last thought: The top ten jobs of 2015 haven´t even been created yet, and in as little as five years, you´ll be running products on your network that are now just a twinkle in their inventor´s eye! Where and how successfully you´ll fit into this future directly and completely correlates to how well you position yourself for these changes now! Stay current—stay ahead, and best of luck to you.

Cheers!
