  • Fortinet, Meru, FortiRu Forti-WHO?

    Since last week’s open letter to FortiRu, I came to the realization that there may be some confusion related to Fortinet’s AP product line.  I decided to throw this post together so that it is easier to understand which APs are what, and which category they fall into.  Keep in mind this is a high level overview to simply point out the different AP product lines.

    Lets jump right into it…

    Fortinet offers three different management options under it’s Enterprise Secure Wifi solution; FortiGate, Cloud, or dedicated controller, and five different AP lines that fall into one or more of those management options.

    Excerpt from Fortinet Product Matrix

    Access points that can be managed via the ForiGate or the Cloud are broken down here:

    Standard 802.11ac

    Standard 802.11n

    Smart APs

    Universally Manageable APs

    The FortiAP-S313C, which was given to attendees of the recent Wireless LAN Professionals Conference, falls into the preceding category.  You can read a great blog post about the FortiAP-S313C AP written by my apple butter lovin’ buddy Lee Badman here.  Please pay close attention to what Lee says concerning the licensing for these APs.  A true game changer…

    FortiAP-S313C

    There may have been some confusion with the FortiAP-S313C stemming from the Fortinet presentation at WLPC.   The FortiAP-S313C is NOT from the Meru pedigree of access points of which I will elaborate on next.

    Access points that are managed from a dedicated controller are broken down here:

    Standard APs

    Universally Manageable APs

    AP1020
    AP832

    These APs ARE from the Meru lineage of access points which I affectionately refer to as FortiRu.  These APs support Virtual Cell/Single Channel Architecture and are still commonly referred to as Meru access points.  The APs in the Standard AP list are all carry over from the Meru purchase.  The AP1020 and AP832 are models that we use in our school district and the models that I have the most experience with.  Both the AP1020 and AP832 have been rock solid since their release to market.  It is often confused that these standard APs are only capable of operating under Virtual Cell/Single Channel Architecture.  All traditional Meru access points can operate in EITHER a multi channel OR Virtual Cell configuration.

    You may have noticed that under each section there was a group of APs referred to as Universally Manageable.  These APs can be managed using any of the three management solutions.  Just like its’ Meru predecessor, the Universal AP can be used in EITHER a multi channel OR Virtual Cell configuration depending on the chosen management solution.  I should have more to write on the “U” line of APs in the near future as we should be receiving some very soon.

    As previously stated, this blog post was intended to be a high level overview of the Fortinet/Meru (FortiRu) AP product line.  Clicking on the links and reading through the material will give you a deeper explanation into each of the access points.  As always, if there are any questions, comments, corrections, etc, please feel free to reach out to me.

  • Dear FortiRu; An Open Letter of Affection, Disappointment, and Encouragement

    Dear FortiRu,

    You and I have been together for almost seven years.  We have been many places together; local government buildings, soft drink distributors, beer distributors, small town banks, surgical tool manufacturing facilities, resorts, retirement communities, many private and public schools (too many to count), and Thomas Jefferson’s Monticello (Remember TJ’s attic?).  We have had ups and downs but to be honest it has been mostly a positive relationship.  I will admit, there was a time when I didn’t want to talk much about you and I, afraid of what others would think, but I eventually professed my affection for you publicly.  Many out there were launching arrows at you and it became too difficult to stand by and watch you take hit after hit.  You would get criticism, some just, but mostly un-just, from people that barely knew you or didn’t know you at all.  I tried to jump in and take bullets on your behalf.  People kept firing…

    It has been nearly three years since we reached a milestone in our relationship.  Some milestones are good, some not so good.  I’m not sure which one is a good reflection of us yet.  Some people probably wonder why I care so much about you.  My answer would be that after you have been with something for so long, it becomes part of you.  I feel like I have so much invested in you.  You have been great for me and my career!  There are many more fish in the sea and sometimes I think I might be better off somewhere else, but I always find my way back to you.  You have been there since I decided to really focus my attention on wireless technologies.  You have been there as my career blossomed and you have even give me opportunities that I may have not had otherwise.

    My questions for you at this point in our relationship are this; where do you see us going?  Do you think we have a future together?  Not necessarily where everyone else is going (MCA), but with something that our relationship has a FOUNDATION on (SCA\Virtual Cell)?  All those other choices out there seem so much alike.  Some are built in the cloud, offer similar features, and solid reputations, but you… you are different!  You have something special.  You have something that others have tried but have failed at.  That cute little thing you do (SCA\Virtual Cell) “may” be getting a little stale, but there are so many advantages and unrealized potential.  I was hoping so badly that the milestone I spoke of above would bring a revitalized fire, and I hope that it still might!  There have been GREAT improvements since that milestone but I just don’t see where you want to be yet.  I am concerned for you.  Do you want to be like everyone else or do you want to be unique and build on something great?  How would Dr. Bharghavan, Srinath Sarang, Joseph Epstein, and Sung-Wook Han feel about the direction you are taking?  I know you might not care what they think anymore, but they are the ones who brought you into this world.

    People ask me about you all the time.  They ask how you are doing and what you are going to do with your future.  I can’t answer those questions.  YOU HAVE TO ANSWER THOSE QUESTIONS!

    I was present recently when you talked about some things that you have been going through.  There were a lot of people around (Wireless LAN Professionals Conference 2018) and I was so excited to see you stand up and start talking.  I thought you were getting ready to have a breakthrough and let everyone know how awesome you can be… but then I was let down just as quickly as it started.  I’ll be honest, I was a little embarrassed.  People around me noticed how excited I got when I saw you and then they noticed how quickly I was let down.  You did a great job talking and the presentation was fine, but I couldn’t help but think it was a little fake.  It wasn’t who you really are.  I felt like you were just saying things you thought others wanted to hear.  People told me afterwards that they would have rather heard you talk about WHO YOU REALLY ARE, but instead you were “like all the rest of them.”  Love you or hate you, people just want you to BE YOU!

    I’ve been places and heard those other fish in the sea speak about themselves with confidence.  They keep wanting so badly to improve themselves, make themselves look good, and be accepted.  I can’t help but notice that it seems like you don’t care about everything that makes you who you are.  It seems you don’t remember where you came from, almost like you are trying to be someone else.  The world doesn’t need followers.  They (the others) all look the same to me.  I love you for who you were, who you are, and for the potential that you have.  Please don’t fall into the same line all of the others are in.  You were about being different.  Don’t lose sight of that!

    There are so many people out there that know your potential.  I know they might not always outwardly express their feelings, but they tell me.  They tell me to fight for you and tell me to be patient… and I will, but I can’t do it by myself.  I need your help.  I need you to be confident in yourself.  I need you to help me.  It can’t be a one way road like it has been.  Help me help you!

    I can’t speak for the future and what others feel, but I can speak for myself.  If I don’t see effort in this relationship, I don’t know that I can continue on.  I will still work beside you and be your friend, but I can’t guarantee that I will have the fight in me anymore.

    No matter what happens, I will always care about you.  I just hope that you can figure out who you really are.  You might already know but just haven’t told anyone yet, and that is ok, but just know that you are not helping anyone, including yourself.

    I am writing this letter to you, not because I want to break up, but because I care about you and your future.  I know you have great potential even though I don’t know exactly what the future looks like.  There are so many people pulling for you, I promise.  I hope my future has you in it.

    (Hopefully) Yours always,

  • #WLPC 2017 PHX, #SingleChannelAdventures, and Looking Back

    It has been a couple weeks since I returned from WLPC in Phoenix.  It was a great trip down to the southwest which included catching up with some good friends, listening to great presentations, learning a lot, and also presenting on a topic near and dear to my heart.  I was able to put a lot more names to faces and have some great conversation.

    As many of you know I presented on how well single channel architecture works for us.  You can find the video below:

    I have received mostly all positive feedback on the presentation.  It was a great opportunity for me to speak in front of a large crowd and give examples of how we have Meru deployed across our school district.  As well as it went, I feel like I need to explain a few things.  I have come to the realization that a Ten Talk may have been the wrong platform to discuss the topic at hand.  I understand that most people wanted more information about SCA rather than “it just works for us.”  Ten minutes was simply not enough time to discuss all of this.

    First, I understand that being a large network doesn’t equal wired\wireless networking done right.  Even though this wasn’t conveyed in the presentation, I have received feedback indicating as such.  Although we are very proud of how large and successful our network is, it doesn’t mean that large = successful.  A lot of time and effort goes into making a wireless network work well for 60,000 users on average every day.  We all know that architecture doesn’t matter if you don’t define, design, implement, and validate.

    Second, I gave some confusing information.  I realized shortly after the presentation that the stat showing that we “average ~12 connections per AP county wide” was very vague.  Some of our access points have upwards of 100 clients on them at once for an extended period of time.  Some of our access points have 10 clients total (maybe less) in an entire day.  It doesn’t matter whether there is 30+ clients on an AP during every class or another AP that sits unused for the majority of the day.  If an AP was placed in a location, it was done there with the intent that wifi could be needed at any point of an instructional day; planned or un-planned.  The opinion that there are too many APs or not is irrelevant.  Unless you have actually visited our schools and used the network, you won’t know.  The proof is in the pudding so to say.

    I know that most of us consider our wireless networks as mission critical.  The vast majority of our schools don’t have desktop computers other than in administrative areas.  Many of our schools don’t have computer labs, but employ several carts of mobile devices.  I know that most of us want NUMBERS to back up the user experience, but most of the time I don’t have time to get this type of information.  If reports of “wireless problems” are low or non-existent and teachers are able to complete their instruction using mobile devices and be successful, our mission is accomplished.  I know a lot of you won’t be happy until you see NUMBERS and that is fine.  I am going to try real hard to get some of those and put them out there.  To be perfectly honest, I don’t know if some of you will believe it then, and that is fine too.

    I understand many of the things that have been said as far as physics, airtime consumption, high density, etc.  I don’t necessarily disagree with some of the opinions.  You may be absolutely right!  The thing that is somewhat discouraging is that there are a lot of opinions based on no experience or an experience that was several years ago.  Don’t get me wrong, the first time I saw virtual port, even with my limited wireless knowledge at the time, I couldn’t believe it would work.  A lot has been improved upon since then with virtual cell and especially the equipment.  I’m not saying Meru will beat another vendor head to head every time, but I bet it will sometimes!  Does it really matter how many jigabits we can ram through the air or is it more important for a user to have an experience where they don’t even notice the wifi?  A user sits down, opens their laptop, completes a task, closes the laptop and moves on without even acknowledging the presence of wifi.  The wifi just works.  Please understand, I am not trying to discount numbers such as channel utilization, retries, available bandwidth, etc.  Those are all very important things to consider in a wireless environment.  We all look to those numbers first when trouble is initially reported.  Those are the numbers that give us a baseline to begin troubleshooting.  They are absolutely critical to a successful wireless deployment.

    Obviously interest has been piqued since the presentation.  It has been fun, most of the time, discussing various aspects concerning single channel vs multi channel environments.  I have heard a handful of different people give a handful of different explanations on what Meru’s special sauce is, and they are all different.  There isn’t a ton of information out there concerning the “magic” of Meru but if you are truly interested please watch any video by Dr. Bharghavan, founder of Meru networks.  Many of these videos are a few years old, but still offer great information.  To be honest, I need to re-watch most of them as I get tangled in the “it just works,” sometimes.  Below are a handful of videos.

    Conclusion

    For those of us who went to WLPC 2017, we heard more than one person mention that wireless networking can be done in more than one way.  We also heard that less than ideal practices may be employed against our better wireless judgement due to other factors such as politics, aesthetics, etc.  Sometimes I think we need to remember that just because someone does something different doesn’t mean that it is wrong.  We also need to remember that just because we don’t like a technology it doesn’t mean it doesn’t fit someone’s need.  I need to remind myself of this from time to time.  We deploy wireless networks, in schools, mines, warehouses, large refrigerators, outdoors; you name it, we put wifi in all kinds of places.  Our ultimate goal should be to use the knowledge we have to deploy a wireless network that gives a reliable experience to the greatest number of users.
