There are others on here that can explain it far better than me. However, here’s a shot:
1. The Preseem system doesn’t use Deep Packet Inspection. It uses FQ-CoDel to manage the queues to ensure better experience for the customer. So they can prioritize traffic that needs instant response like clicking a link on a web page versus filling the buffer on the Netflix client. 2. Customers are soft limited to their plan amounts. By this I mean that their traffic is managed more as they approach their plan limits which reduces the abrupt web page not responding types if issues if their streaming is gobbling up their connection. 3. Customer speed plans are managed in the Preseem appliance rather than Mikrotik queues. This is significantly simpler when integrating with Sonar, Powercode and others. Very much a plug and play installation I know there is more to this technically, but I wouldn’t do a good job of diving into it as we didn’t need/want to get that deep into it. We just needed to confirm it did what they claimed. Again, we bought it for the traffic shaping, but the pleasant surprise was the troubleshooting tools with it. I think our surprise wasn’t that we got some extra tools, but how accurate and useful they were. It is hard to oversell that.

I'm guessing it looks at TCP performance? How does it do it? Deep packet inspection? Seems tough to do without overwhelming the server or increasing latency significantly.

We originally implemented it as a way to better manage the customer experience and potentially make better use of our DIA bandwidth and maybe reduce some DIA costs. I am guessing someone could build a similar product on their own with open source. However, what we have found is that we get significantly more than the customer experience management with the tool. The reporting is beyond awesome, it has become our number one tool for troubleshooting customers complaints. Others on this list can weigh in on how they use it, but our typical day goes something like this: 1) During our morning Ops call, we take a peek at Preseem's recap of tower latency yesterday. If nothing new shows up for Red towers/access points, we look at Yellow Access Points (this is a ranking of Aps/towers over certain latency thresholds) 2) If any customer calls have come in, we use the Preseem tool to see if they are experiencing latency issues. If they are, we check our SNMP based monitoring tool to see if their wireless connection to the tower has changed or if the AP is experience issues. We had a pretty major windstorm go through two weeks ago, and we found a few customers whose latency spiked and investigation into their connection showed there was an issue with their dish. 3) If latency has climbed, but the AP and upstream devices are all OK, we check into the experience of that customer to others on their tower. Is their latency spike unique, does it happen only under load, etc. More often than not, the issue is specific to them, doesn't only happen under load, and only at certain times. It is usually from streaming a show on the TV in the far back upstairs bedroom (or something like that) with a crappy connection to their wifi router in the house. We have found it to be an indispensable tool for this kind of thing. We bought it for QoE, but use it daily for monitoring/troubleshooting activities. Not only do you get a hosted reporting solution, you have access to some pretty smart folks. Just this morning our first line of support person said "If Preseem ever goes down, I will cry, it is my favorite troubleshooting tool". We were having a discussion about how you could compare QoE/Latency from a customer to other customers on the same AP, to others on the Same Tower, to others in the same DIA, etc. It is hard to explain how much it changes the way you think about the "My Internet is slow" complaint. Quite often this person will get a call about it being slow last night, and she will ask the time at which it happened and pull up very detailed information like "You were using 45 of you 50 Mbps plan with 50 ms latency". Take the time to go through the demo with Gerrit. You may not decide it is not for you, but it won't be a waste of time to understand why they are pushing it so hard.

You sound exactly like I sounded 15 years ago. The more stuff I have to deal with every day, the more I'm ok with outsourcing some of my troubles to someone else. I just paid a guy $800 to replace an exhaust inducer in my furnace. I know that inducer is $99 and goes in with 4 screws and a hose clamp, but it's more worth my time to let someone else take care of it so I can do something else. Same goes for Preseem vs the $300 Linux box. I'm not knocking your method. There's a point in the business cycle where there's more time than there is cash, and it will make sense to do some more DIY things. I'm just saying the Preseem thing has value too. -Adam On 1/31/2020 11:34 AM, Dev wrote: > I’m getting spammed like every day with the Preseem guys selling what seem > like expensive hacks of fq_codel to reduce bufferbloat.
