  1. Hi, thanks for the links! I will definitely have a look. Also, I understand your unspoken guidance. (like, get out of the weeds dude :-)) All I really have to do is reveal that I thought about it and took a cursory look. I won't let it become a lifestyle. I promise.
  2. Thank you! The only "knob" i can find to turn on "packet size" in the switch gear is "allow/ don't allow Jumbo Packets." I have not found any "settings" to influence packet size in the TV interfaces. I suspect there are knobs to turn on the boxes with full blown Operating Systems but they are not really the devices that concern me at the moment.
  3. Hi, Looking for a good reference book on networking but, There are lots of networking books for sale, and mountains of research papers - all of which concentrate on some part of networking. I am not sure what part of networking might hold the answers to the questions I have. I'm hoping to limit my search by first asking here. Looking for - anything published that looks at bits and bytes in terms of 'work?' Perhaps some characterization of work versus overhead? I checked my test data csv file and our conversion here at TMN is pretty much a straight "divide by 8," which makes perfect s
  4. I'm interested in this. And, no need to apologize. As far as one party screwing up what what the other one does, that is what they do. The people who elect them count on them to do that. I would love to talk about personal freedom and human rights but at the moment I really would like to hear about the open internet. I am actually writing something about that, so please - how is the open internet being taken away? (Sincere question) I can definitely use some ammo. thanks, --John
  5. Got it. Equinix, naturally. As it turns out, there is a difference in both upload and download speed when selecting different mirrors. I had to run a LOT of tests to see it, but I withdraw my question.
  6. Thanks SpenceTeeth. And I noticed CA3LE hit the "LIKE" button so I'm assuming ca3LE agrees with you. But dude(s), "pay no attention to the man behind the curtain?" (Wizard of Oz) Really? 23-3/4 hours per day I totally agree with "not to worry." The devices on this local net are all running well. But for the 15 minutes per day that I'm thinking about this stuff-- the result is either 1) erroneous, or 2) it reveals an upload limitation beyond what I currently know about. I suppose you could say, that's what I do "out of boredom." :-) But, that would not quite be true. That also
  7. As part of today's testing, I ventured out into new territory by changing the mirror location. Until today, all single path testing has been done with the Dallas mirror server. After selecting all the various US based mirrors, an unexpected and perplexing story unfolded. Download: I get the same speed test results using any mirror in the US on download speed tests. Upload: On Upload speed tests, I get my ISP capped limit (40Mbps) from Houston to Dallas, and I get approximately 15Mbps consistently from Houston to any other mirror in the US. I have not tried the mir
  8. Having more experience now with TestMy, I realize the significance of the ISP is not as I had believed earlier. The ISP rank is formed by the tests the TestMy members (and guests) are running. My connection to suddenlink, for example, (aka suddenrage) is pretty fast so I can drive the Suddenlink rank up by running a bunch of download tests. I can watch it change because it updates very quickly, unlike the member rank tab on the suddenlink page which updates, seemingly, only by special request. Again, the ISP rank is a result of whatever people are doing at the moment. Thus the results should b
  9. Hi @mudmanc4, I would have to read a couple of books or go take a course just to understand what you just asked me. So, no. Time permitting, I may. I have often read manuals where Port Forwarding settings are identified. They tell me what do do, were I to desire to forward a port. However, I have yet to find anything that tells me why I would want to do such a thing, or what the typical (or intended) use of it is. Just curious, sidebar: off topic, what do you have on your head in that picture?
  10. I don't know. I'm not certain that is going to reveal what I'm looking for, but it could still be interesting. I think it depends on what the so called router does with the traffic. If all of the traffic is sent to the ISP's routers to determine what to do with it, then the test result may be of interest. All of the hardwired ports on that box are bridged. It has one port named the modem port which is an actual gateway port. It should send local traffic to the local bridge but that is not a guarantee. I'm no routing expert, but the 192 addresses are assigned the local bridge interface, but the
  11. Ultimately, my purpose for testing, and the original reason I got involved with TestMy was/is in preparation for self-hosting one of my domains. My facility is combined residence/business. I pay the ISP the residential non-commercial rate. The domains are currently hosted at BlueHost. After reading about NAT, it seems that it may cause issues for my self hosted domain, Rather than try to itemize all the ways NAT would interfere, I decided to that getting on IPv6 would be a good idea. My ISP, which is Suddenlink/Altice, is silent about IPv6 on their site. I am (time permitting, and it take
  12. I spent a lot of time getting Upload tests to run at the full ISP speed. Until I figured a out correction that got rid of the mid-var, my Uploads had terrible speed (5Mbps). This caused me to associate mid-var with bad speed. But look at this download test result graph. This time the mid-var works in my favor. I am referring to the upward bump in the middle.This test was run on a connection limited to 400 Mbps (ISP tiered cap). Although it is preceded by a downward bump, the downward bump never went under 400.
  13. I have not yet been able to read anything about NAT without getting a foul taste in my mouth. Thanks for the info.
  14. I may need to revise that remark. Lately I am seeing instances of data points on my results graphs that are much faster than the ISP speed limit for my account. What tends to happen it is a bit of oscillation above and below the speed limit, finally converging on a more or less steady set of data points, and indicating a lot of middle variance. I have not changed anything. This is new. But, it the speed limit was set by setting fixed modem clocks, data would not be able to go faster than the modem speed. Thus, I remain open to the idea the ISP is measuring something else. (queue length/time,
  15. Sean, thanks, I really wish I understood what you have said here. Are you saying an ISP (via their DHCP server) will issue the same IP address to many different customers ?
  16. Background My ISP speed is clamped at 400 Mbps Down, though I have been routinely getting 430+ Mbps. I have a 1 gig infrastructure in house. The direct-attach router ports are consumed by L2 switches and one Wintel computer. I execute TMN tests (Loc 1=multithread, Loc 2= normal) from the Wintel box. Reconfigure for new test plan I am about to introduce two more locations (TMN Identifiers -Loc's 3/4) which will be a pair of laptops. When attached to available L2 switch ports, each of the laptops produce TMN download test results near identical to the Wintel box I ha
  17. This results on this tab seem frozen in time. Fastest ISPs-->Suddenlink-->member rank (tab)
  18. Interesting. So, if their own "blessed test" is a meg off, I think you already have a case to present. I don't know whether you already have <?> Are you mandated by CenturyLink to use that specific router? I am really not happy to suggest spending money, who the heck wants to do that. But, an ISP only believes one configuration is legitimate when discussing your issues - and that is for your systems to be attached directly to a modem. In your case, you cannot do that since it is all built into one integrated entity. If you were inclined to separate the modem from the switching and W
  19. In this context, jitter is a statement of deviation. In fact, engineers/techs who only work on tcp/ip networks will also use the word synonymous with "late packet arrival." I have never looked at what exactly the n% means but lower is better and I think 2% is probably ok.I saw something about it on Wikipedia, but It gives me a headache to think about it simply due to my objection to the word being used in this context at all. In all other areas of engineering it describes a deviation from a fixed expected rate. I would love to hear somebody tell me how a packet switching network has or ev
  20. know what happens when you run the ISP test, if you are so inclined. By the way, fixing the middle variance did make a big difference in my overall TMN results, especially on the upload side. sorry for two posts, I hit the wrong button or something while trying to undo the caps lock
  21. RMcQ, yes, TestMy.Net is a great resource. I never see any ads so no telling how they get paid. Possibly selling the test results. Or maybe collecting from the ISPs for a better service resource than they have Who knows. Anyway, back to the topic, does centurylink have a speed test of their own ? If so, it is likely an Ookla based test. The results of those have to be used carefully, but they can provide an interesting data point. I ask, because you have a 5% middle variance. I spent some time fighting middle variance and it was the ISP Ookla speed test that gave me the hints I needed t
  22. Interesting question. There are several ways to do it. Each has less or more merit depending on the goal. Given that an ISP's goal is the managing speed limits on a per customer basis, and the fact they tend to discuss (and sell) "speed" in terms of bits-per-second, my guess would be they are throttling at the signalling level versus measuring and capping a "byte flow" inside their switching gear. If I am right about that (and that's a big if) then the modem at their end, that your modem talks to, would set the max transmission speed. I really don't think it would be practical for them t
  23. Hi, sorry for your troubles. I can totally relate to what you have been through. Just curious, if you don't mind ... the gear that they brought to your house, is it mandatory to use their equipment? Asked another way, do you have a choice of using your own internet access equipment? (modems, routers, switches , whatever) Second, the Hughesnet equipment, what are the brands/models they use ?
