Ashburn, VA | Re: then why doesn't my 20/20 give me 20 up? said by VZFiOSYo:Circuits are being provisioned as 25/25 symmetrical yes, but upload speeds vary. Is that because a GPON OLT with 32 users is being strained at 25Mbps per user? Is the varying speed user dependent or a limit of the FiOS infrastructure? It's one thing to have somebody expect to upload at maximum speeds to each and every test site or server they are connect with, but if this is a problem with the FiOS network capacity, that is a completely different situation. Quite frankly, this is the one thing that has not been made clear to me, and I have read just about everything I can find across dozens of forums.
Why would there be fluctuations in the uploads, when before these upload speeds were rock-solid stable at the provisioned rates, minus the typical TCP overhead? | |

Because as more and more users get FIOS in a specific limited area the bottleneck is no longer the last mile, but in aggregate links further upstream. Even Verizon is not immune from the nature of the internet.

Ashburn, VA | Re: then why doesn't my 20/20 give me 20 up? That's just another guess, but it doesn't really tell whether or not the uploads are being limited by the immediate FiOS infrastructure or just the individual user configuration to wherever they happen to be uploading.
Sustained test using actual files have indicated that maximum provisioned speeds can be reached for prolonged periods of time. Albeit, these types of test are far and few between, but a few people have posted their results.
Most of the test information we see is based on speed tests to a flash site. These variances are seen with as little as 10 ms latency, which would just about rule out any congested routing issues between the user and the test site. Perhaps Speed Test.net does not have the necessary capacity to handle these upload speeds with any consistency?
If the limitations are completely within the limits of Verizon's network they may need to make some improvements. To me, this is exactly what it sounds like. Verizon can only guarantee up to 15Mbps, because they can't handle the full load of 25Mbps. That will be fine, provided that my tier can always reach 20Mbps like it currently does now. I don't want to be restricted in the same way that those paying for 25/15 might be, especially if I am thrown into the same "hit or miss" group with my uploads.
This worries me. I don't want to be a part of an oversubscribed network after enjoying the service I have had for the last 8 months. | |

| Re: then why doesn't my 20/20 give me 20 up? 2.4 gig between 32 subs? you think youll be oversubscribed? Even if all users are maxing out equally doesnt this leave 75 meg for each? 95% of users are hardly using these connections at a constant rate. Sorry , but they can give everyone 100meg service and youll very rarely see fluctuations. | |

1 edit | Re: then why doesn't my 20/20 give me 20 up? Well, I can have a Gigabit LAN to go with my 50/20 WAN. The congestion point may not necessarily be in the last mile, but just a step or two beyond. Even if 12 servers on my LAN are seeing terrific speeds while transferring files amongst each other, if just a few computers attempt to upload large files over the WAN, they will all see their file transfer speeds drastically reduced. Perhaps a similar situation is occurring with FiOS? Maybe the GPON(or BPON) OLT/ONT is our "Gigabit LAN", and there simply may not be enough capacity to handle full speeds leaving the local FTTH networks in certain regions?
Edit: I suppose the biggest issue that throws me for a loop is if the choke point is further upstream and a result of several FiOS customer all clamoring for speed in a given region, why is it that only the upload is significantly impacted, and not the downloads as well? | |

| said by VZFiOSYo:Circuits are being provisioned as 25/25 symmetrical yes, but upload speeds vary. It shouldn't for the "older", "standard" *symmetrical* 20/20 package (which was introduced a year ago, an upgrade from the even "older" *symmetrical* 15/15 package).
I consistently get 19/18 on my 20/20, and have been for a good year now. | |
