Nighttime slowdown again in Verizon Fiber Optics http://www.dslreports.com/forum/r22594428 en Sat, 05 Dec 2009 01:49:16 EDT Sat, 05 Dec 2009 01:49:16 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22659266 Tollhouse : this may sound like a dumb suggestion....

but back last year when i was a phone tech/floorwalker (supervisor) for Verizon at the new contract center here in WV, we'd occasionally get customers that would have these issues and after going through the 'standard' bevy of troubleshooting steps, we'd escalate to an NT internally and they'd rebuild the circuit for us just to rule out a bug in the circuit (and this fixed the issue 99% of the time, as it usually just was a wierd glitch/bug).

Have you tried asking tech support to contact an NT for a circuit rebuild? It takes the NT like, 2-5 minutes to do it once he/she has confirmed all other possible steps have been taken.]]> http://www.dslreports.com/forum/remark,22659266 Mon, 06 Jul 2009 00:29:29 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22647938 Hispanic : 11:23pm

Here is some general info on the behavior of FiOS VOD.

»Re: [VOD] FiOS on demand hogs 15Mbps for 720p

Verizon definitely does some back end stuff with the bandwidth and VOD, and maybe they have their wires crossed, in a manner of speaking?]]> http://www.dslreports.com/forum/remark,22637693 Wed, 01 Jul 2009 00:13:39 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22637516 Hispanic : Interesting.. So if someone with Fios is watching a Vod, their download speed will decrease similar to what i'm getting?]]> http://www.dslreports.com/forum/remark,22637516 Tue, 30 Jun 2009 23:18:37 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22637492 jmn1207 : It just seems as if the same amount of bandwidth lost is about the same as a typical VOD program. If you are experiencing a prolonged, but stable, decrease in download performance, I wonder if something could be misconfigured at the OLT/splitter? It's even more suspect, to me anyway, since you don't have TV service.

Perhaps this can be ruled out without having a tech come out? I'm just throwing something out there. I'm probably way off the mark, but your problem is weird enough to warrant odd ideas. :)]]> http://www.dslreports.com/forum/remark,22637492 Tue, 30 Jun 2009 23:12:53 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22637355 Hispanic : It seems to only occur late during primetime.

That's about all I can suggest you try on your end beyond putting in a ticket with Verizon and pursuing things that way. Maybe they can have someone take a look at it during off-hours when it's occurring.

Last night I took the dlink completely offline and put the actiontec in its place to isolate the router issue. I had the same results with the actiontec.

As far as speedtesting, I only mentioned the laptop because I wanted to try different/shorter ethernet cables which would allow me to bring my router right next to the ont and plug my laptop's nic into the router. I know it isn't a problem with the cable after that testing.

I had the same thought as MacAlert. I find myself wondering if someone isn't occasionally somehow leeching off your connection. The symptoms you're describing seem too typical for cable service, but atypical for FiOS.

It's been well documented that WEP is just a little better than worthless when it comes to securing wifi. Next time the slowdown happens, why not turn off off wifi in the Actiontec and see if that pops your speed back up?

Or, take a look at the Actiontec status screen and see if there's anything you don't recognize on the My Network page.]]> http://www.dslreports.com/forum/remark,22614507 Fri, 26 Jun 2009 10:57:01 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22614433 Hispanic : Deblin, thanks for your help. I will just keep a close eye on things. I posted in the verizon direct forums and someone is helping me.

MacAlert, no that is not a dumb question. But the wifi on the dlink is secure with wpa2 (n-only) and the actiontech has wep security by default so that's not the issue.]]> http://www.dslreports.com/forum/remark,22614433 Fri, 26 Jun 2009 10:45:51 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22613939 MacAlert : This might sound dumb, but is anyone else accessing your WiFi?]]> http://www.dslreports.com/forum/remark,22613939 Fri, 26 Jun 2009 09:23:32 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22613816 deblin : So the router thing was just coincidence? Bummer...

I think you need to get tier2 support involved and somehow have them monitor things when it's going bad. Which is going to be tough since it's happening off-hours :(

Compare the two sequence graphs you see attached.

Ideally, the sequence graph should be a perfectly straight, continuous line at ~a 45 degree angle. Note that the actiontec graph is just this - after the initial TCP window ramp.

Then look at the dlink image. See how it's wavy and sort of "squiggly"? This indicates some sort of RTT delay, be it packet queuing, packet loss causing retransmissions, etc.

Bottom line, the actiontec graph looks healthy, the dlink looks quite unhealthy. Even when you were pulling ~20Mbit/s from my with the dlink, it's still erratic and the reason it probably didn't affect things as much is because the latency between our two hosts is probably quite low.

Even tcptrace's generated throughput graph via xplot looks funky.

But you did say the speeds were closer to 20 Mbit right?

I'd definitely say the next time the slow downs crop up, drop me an IM and I'll put that test file back in place and you can test again.

It could be that the problem lies on your route to the internet at large, but the path it takes to me is different and not subject to the problem. If we can determine that, it'd rule out your local equipment and ONT I'd think.

From your IM, I see that you're on the 96/8 network. Have you tried releasing/renewing your IP until you land on a different IP block?

We estimate your uplink as having 68 msec of buffering. This level may serve well for maximizing speed while minimizing the impact of large transfers on other traffic. We estimate your downlink as having 2100 msec of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large downloads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large downloads at the same time.

Network bandwidth measurements: Upload 16 Mbit/sec, Download 1.4 Mbit/sec

Your Uplink: We measured your uplink's sending bandwidth at 16 Mbit/sec. This level of bandwidth works well for many users. Your Downlink: We measured your downlink's receiving bandwidth at 1.4 Mbit/sec. This level of bandwidth works well for many users

Minor Aberrations

•Network packet buffering may be excessive
•Your computer's clock is slightly slow

If you're willing, I can put a test file up on my web server (on a 25/15 FiOS connection) and let you grab that, and capture it from this side to see if I can find any anomalies that show up from the server side.

If you want to try that, shoot me an IM with your IP so I can filter the PCAP accordingly and I'll IM you back the url to snag.

I do see the checksums are wrong, but that's usually just because TCP checksumming was offloaded (not sure if Windows does this or not), which I've seen on older Realtek cards.

@ Hispanic: Suggest you run it just long enough to get a good capture on packets when your timing is down. Downloading the full 1 gig will be a very large pcap file. Look for file size that will give you 10 or 15 seconds capture.

I think there's a limit of how much DSLR will accept as an uploaded attachment.

ip.addr == 167.206.5.41

Then click apply.

Then you should be able to click on the capture menu, then start (you might be prompted to pick an interface. If so, somewhere in the preferences/config you can pick which interface to capture on. I'm not entirely sure where that's done in the win32 wireshark).

And you did say that multiple different speed test sites also show the same slow downs, right?

One other useful bit of information would be whether this is a digital transition or analog.

What I mean by that is: Does the connection go from 20 Mbit to 9Mbit at nearly the flip of a switch, or does it slowly degrade from 20 down to 9 over the course of an hour or two/etc?

I take it you've tried unplugging ALL internet-connected devices during these times and testing individually from each connection while the rest are off to rule out some sort of malware phoning home at this time or something?

The next logical step for me would be to run wireshark or similar and collect a packet capture while you're downloading from the ftp1.optonline.net FTP server and posting up the pcap dump from that so we can take a look and see if the connection looks like it's congested or if there are dup ACKs, retransmissions or what.

...since the OP's upstream tests were good, downstream ACKs are not being delayed, and therefore downstream congestion is not an issue.

The downstream ACKs require/consume very little bandwidth. Far less than the downstream throughput the OPer is getting, so of course down stream ACKs are unlikely to be impacted enough to cause upstream slowness.

I'm inclined to think maybe the OPer has something running unaware. Or maybe if the OPer has FiOS TV the STB is doing something weird. Also if this is with WiFi a whole host of things could be in play.

Another thing that is interesting is the 0 ms ping in one test and then 10 ms ping in the next.

But in speed tests aren't the upload and download performed at different times? So one should not have any impact on the other?
Yes, the download and upload tests are performed separately. That is not what deblin See Profile was talking about.

For each block that is transferred (up or down), there is an ACK that flows in the opposite direction. If there is congestion in the direction the ACKs are flowing, the ACKs are queued and not sent as quickly as possible. This throttles the sender until the ACK is received. There is more involved, but that's the general idea.

What deblin See Profile was trying to point out was that since the OP's upstream tests were good, downstream ACKs are not being delayed, and therefore downstream congestion is not an issue.]]> http://www.dslreports.com/forum/remark,22600937 Wed, 24 Jun 2009 01:07:28 EDT Re: Nighttime slowdown again http://www.dslreports.com/forum/remark,22600660 N O Y B :

Is it overcrowding?

Given your upstream seems to be running fine and that the upstream on the BPON/GPON is lower than what's available on the downstream, I doubt it's a case of congestion. If it were, I'd expect your upstream to be affected just as much. Why? Because if the downstream were saturated on the *PON, you'd have a situation similar to what happens with ACKs being queued on the downstream side when your upload is saturated. In other words, your downstream would be limiting your upstream. But that's not the case, based on your speed tests...

I'd definitely give verizon support a call and/or post in the direct forum to see what's going on.
