Most Net Techs that I have talked to have heard of quality of service (QOS) but few actually understand what it is. Some have no idea what QOS is supposed to do, while others think that it is the end all be all solution to constrained bandwidth. I am here to tell you that you are all most likely wrong. Instead, QOS is one of the many tools at the disposal of the Net Tech to manage the bandwidth that he/she has, and ensure that critical traffic is able to get across the network with minimal delays.
About a year or so ago, myself and another warrant who was out here helping out with a rotation were looking at the configs for the unit trying to understand what exactly was going on with the QOS. It took us several hours to really understand it. This got me thinking about putting together a small white paper to hand out to net techs to try and explain it to them, and get them to understand what it does, and more importantly what they need to do to make it work. My short paper turned into about a year long project and a 19 page paper. During the process of researching everything, I discovered that I was wrong with a lot of the things that I thought I knew.
My original intent was to post the entire paper here and then leave a pdf copy for everyone to download but after spending just 30 minutes trying to get it all input into WordPress and formatted correctly, I got frustrated and gave up. So instead, I am writing this brief introduction, and just posting the paper here for you to download and look at.
So what are you downloading? Well, the main file is “QOS WIN-T Inc 1A”. It is a 19-page document that explains in a fair bit of detail what QOS is, how it is implemented in WIN-T Inc 1A and what you as a net tech need to do. The next file is a Visio file that lays out step by step an example of QOS at work. The description of the what is going on is included in the first document but the Visio file really helps to lay it out. The final file included is a QOS bandwidth calculator. I didn’t make the calculator, although I have modified it a little bit. Unfortunately I am not sure who made it (I got it somewhere along the road) but whoever did….Thanks
Please note, this paper applies to WIN-T Inc 1A only although a good chunk of it applies to 1B also (I just haven’t taken the time to sit down and figure that all out yet). I plan on writing more about this in the future. If you have questions or additional comments, please send them my way so that I can fix anything that I may have overlooked.
Due to some concerns by a number of people, I have decided to temporarily remove the documents from my site here and posted them to MilSuite. As much as I hate MilSuite for a number of reasons, for right now it is the only way I can store FOUO documents.
