E-Sports in schools is becoming mainstream. You can make a living at it as well. Having the right amount of bandwidth for it is essential. It doesn’t matter if that bandwidth is in-house on a LAN situation or over the Internet. Playing or even practicing suffers when a game doesn’t get what it needs. (for you readers on the other side of the coin that need to make sure other things get done without gaming interfering keep reading too :)

Believe it or not, playing games online was one of the reasons I got interested in bandwidth management!

Every FPS (first person shooter) player wants to have a gaming experience where the only reason they lose is because they met someone better than them. You don’t want to lose because you see your screen freeze waiting for the next packet to arrive to refresh the screen.

I dove into learning as much about Internet/Networking as I could so I could try and get the best setup I could for my network. I ran my own servers so I could control some of that. I never played on the same network as the server back then because that wouldn’t be fair to others. Running my own servers I could also see what else was going on with the network traffic.

I knew how much my servers needed per person to play like they should so I knew that 8 or 16 players would take a certain amount of bandwidth. I knew how much total bandwidth I had for the network. What I didn’t know was how much all the other machines on the network was using and how.

With NetEqualizer you can easily see how much every IP is using. That’s every connection an IP has and how much it is using, that’s the important part. You can tell if your mail server is getting hit hard, or the web server is uploading/downloading huge objects to some offsite IP. If needed you can put connection limits on things with NetEqualizer.

You can also provide priority over getting equalized by the NetEqualizer for your gaming server IP. Even though you have priority on it you can still have a total amount it can use hard limit on it.

In a setting where you want to play games during certain hours you can have rules that go on and come off at different times. For instance if you are in a high school that provides E-Sports gaming then it can be setup so that the administrative IPs all have priority from 8am to 2pm but after that you can take it off and let E-Sports have a bit more priority so you don’t end up getting LAG!

NetEqualizer works both ways, it can be used to give administration priority when you want it to be the most important traffic on the network or you can give programs like E-Sports more priority so your gaming does not suffer when its necessary.

NetEqualizer strives to be a set and forget type of bandwidth manager but it has a lot for the ones that need micro manage it as well. You can set hard limits on IPs, create Pools which have a certain amount of bandwidth and then stick IPs into those pools as members so all the IPs in the pool can use up to the pools specified hard limit. You can set connection limits on IPs. Also the default task of the NetEqualizer is to equalize. If placed on a network without any configuration besides telling it how much in and out bandwidth you have it will monitor all connections from all IPs it sees and when RATIO of incoming or outgoing bandwidth is reached it looks for all connections over a value we call HOGMIN and slows those large connections down so the rest of the connections on the network don’t suffer. A real simple example is if you
are on a standard VoIP call which only uses a few hundred K of bandwidth and someone on the network decides to start downloading a high def movie file from the web. Without NetEqualizer its anyones guess what will happen to the VoIP call. With NetEqualizer its predetermined what will happen. First thing it does is see if there is any reason to look for connections to equalize. If you are no where need your bandwidth ceiling then it does nothing and keeps monitoring. Both your VoIP and download should go along like NetEqualizer wasn’t there. Now if NetEqualizer sees that you are near your ceiling on total bandwidth that you told it you have then it looks for all connections over HOGMIN. Every connection that doesn’t specifically have a priority rule for it will be slowed down by a few milliseconds and this will happen for as long as the bandwidth is near saturation. When a connection is equalized we don’t just do it and leave it that way. We do it in stages so things like fragile FTP servers don’t just drop the connection. We put on a small delay and then in a second or so we check again and if it still needs equalizing and still a connection we put on a bit more and then we do the same routine one more time if things are still needing equalizing. Then we take it completely off and start all over in another second or two.

The NetEqualizer equalizes a connection from one IP to another IP. So if your web server is uploading a file to some IP and its huge then it may be equalized for that connection. The other 100’s or 1000’s of connections to your web server would not be equalized unless they were also over HOGMIN and there was a need to equalize. The same applies to any IP no matter if it belongs to your mail servers or game servers or testing servers. As mentioned above, you can set priority for things like video servers you push out to the world and know those streams would be over HOGMIN but are important enough to mandate they have no equalizing on them.

I just spent the evening advocating for my 90 year old mother, getting her through the bureaucracy gauntlet of a large teaching hospital.  The highlight of my evening was when I had to move my car from in front of the ER entrance, and upon my return the security guard refused to let me back into the ER.  I had essentially been evicted from the hospital.  I’ll spare you the details of the rest of tonight’s carnage as it is not really relevant for a technical product blog, but it did jar a repressed memory from when we were in early startup mode years ago, and I was trying to gain some market traction.

Flash back to early 2005, NetEqualizer was no more than a bundled open source CD selling for less than a decent television goes for these days. Our customers were mostly early adopters running on shoestring budgets.  Encouragement came in the form of feedback from customers. We were getting amazing reviews from smaller ISPs, who raved about how good our bandwidth shaping technology was.  My problem was that their enthusiasm was not translating into larger corporate customers.  In order to survive, we had to leverage our success into a higher-end market, where despite our technical success we were still an unknown commodity.

With time on my hands, and my industry expertise current on the Telco industry, I started writing small articles for trade magazines.  These vignettes were great for building a resume, but not so great at getting the NetEqualizer in front of customers.  With each passing week I would chat with the editor(s) from Ziff Davis and propose article ideas. Slowly I was becoming a respected yet starving feature writer. By necessity, entrepreneurs have to think out of the box, and I was no exception when I hatched the idea for my next article.  The conversation with my Editor went something like:

Me:  “Hey Bill, I have an idea for a new article.”

Bill: “Let’s hear it. ”

Me: “Well, there is big trade show next month in Orlando…  How about I head down there and write a new product review feature for your magazine? I’ll walk the floor and impromptu interview various vendors and put together a review feature with a little insider flair, what do you think?”

Bill: “Go for it! Keep me posted. We can’t pay your expenses though.”

Me: “That’s fine. In return for not getting paid, I hope to use my access as your feature writer to also start some conservations on our Bandwidth shaper, to get some feedback on our direction.”

Bill : “Sounds good, just keep it discreet.”

And so I was off to Orlando.

On trade show day I wandered the floor with my little badge identifying me as a representative of the publishing company Ziff Davis.  I walked booth to booth introducing myself and asking about what new products were being featured.

The strategy was working.  Various marketing executives were eager to tell me about their new offerings.  Once we had a little rapport going, and I had gathered the information I needed for my product review, I would attempt to work into the conversation that I was not only a part-time feature writer, but also a tech entrepreneur. Much to my surprise, most people were curious to learn about my endeavor and our start up technology.  That was until I entered the Nortel Booth.

When I brought up my alter ego personality as an entrepreneur to the Nortel Marketing rep, he blew a gasket and had me escorted from his booth by some henchmen.  It was  one of those demoralizing, embarrassing moments as an entrepreneur that you just have to push past.

Obviously, we kept going and there were many more dead ends to come. I learned just as in the hospital, whether your an advocate for your product, or your ailing mother, you must push ahead and continue to work out of the box.  And yes, I eventually did get back into the ER, and yes, it was embarrassing.

As a reference, here are links to some of the trade magazine articles I wrote back in the Mid 2000’s:

Maybe I am old school, but when I go to a news site, I typically don’t want to watch videos of the news.  I want to skim the article text and move on. I find reading my news  to be a much more efficient way of filtering the content I am interested in.    The problem I have run into recently is that the text portion of news site portals loads much more slowly than a few years ago.  The text portions are starved for bandwidth while waiting for a video to load.  Considering text takes up very little bandwidth it should load very quickly, if not for that darn video!

Solution.

I can easily tune my NetEqualizer to throttle video, and leave text alone, thus I can get to reading the text without having to wait on the video to load.  It may seem counter-intuitive, but slowing a website video down does make the page load faster.

Here is a behind the scenes explanation of how the NetEq enhances the speed of some of the popular news sites when the stories are loaded with embedded video.

• Your browser typically attempts to load multiple elements of a webpage at one time.  So I can’t really blame the browser for the text delays. Both the video and text, along with other images, all load simultaneously from the browsers perspective.
• Video by its nature tries to buffer ahead when bandwidth is available.
• With my business grade 20 megabit Internet, the video buffering will dominate the entire 20 megabits.  The text loading, even though small with respect to data, tends to suffer in the wings when a video download is dominating the link.
• Why exactly the text loading does not get equal cycles to load I am not 100 percent sure, but people who design routers have told me that the persistent video connection once started is favored by the router over other packets.
• The  NetEqualizer by its own design punishes large streams by slowing them down when your link is at capacity.    This allows the text loading a nice chunk of bandwidth to work with and it loads much more quickly than when competing with the video stream.
