Re: 16/1 speeds comcast
A properly configured connection should not be adversely affected when uploading. At least not to the point where your connection is useless until the upload is complete. I have had 3 simultaneous uploads with large files to YouSendIt and continued to stream high quality music, browsed the internet, and even downloaded an ~8MB video file without any noticeable degradation.
Other scenarios had me sending a couple of emails with 5MB's of photos attached while talking over Skype, listening to Rhapsody Music services, and chatting in the lobby waiting for an online poker tournament to begin.
A jump from 768k to 1m may not seem too significant but it is a 33% increase in bandwidth.
As for Comcast's Digital Voice service, it operates on a completely different frequency range than the HSI and neither of them should cause any significant impact on performance on the other. At least that is what I have come to understand from reading about the technology.
I suppose I will find out for sure, today, sometime between 5pm and 8pm. |

Email sure does take up a lot of bandwidth doesn't it;):p |

When I was on 3/384 I could easily impact my incoming speeds. At the time I was downloading a linux distro and was topping out at 3.0 speeds, around the same time I sent a 5MB file to a friend on ICQ and watched my incoming drop from 3.0 to 1-1.5 speeds.
Now FF to today. Incoming speeds have increased over 5 fold while the outgoing has barely tripled. 3-16 speed jump is impressive yes, but in the same breath 384-1
Megabit isn't as impressive. You still have to control your outgoing and do some kind of throttling of speeds on your outgoing so you don't cut into that outgoing that cuts into the DHCP overhead that directly cuts into your incoming speed. :/
Comcast should be offering 16/2 not 16/1, that outgoing is just way too low. |

Connersville, IN | You could benifit from setting up bandwidth limits on the upload side ... That way you will have enough to go around ... Less upload speed per user but no more "choking"

Its the nature of the technology. Perhaps with the recovery of analog spectrum, newer high performance docsis standards and signalling, and small node domains, we will see what you are looking for.
Give it a few years, as network convergence (service convergene: voice,video,data) occurs across all providers, network performance and competition will increase. Cableco's are kinda sitting on their but while teclo plays catch up... case in point: FIOS vrs HSI
Note: DHCP is an addressing protocol and has no overhead that you reference to. TCP is the overhead you might be refering to and its overhead is a semi-variable constant on any network.
Im just echoing the answer to your question that has been generally passed around this forum and the industry as a whole. I wait for syncronous connections just as egerly as you all. |

| I've been dealing with Verizon so much lately. I've been on the internet for a long time....heh
They keep referring to PPPoE being better than DHCP, less packet overhead etc. Regardless of it being true or not, I would choose DHCP any day. I dislike the idea of "dialing into broadband"
Even Verizon's 15/2 plan is very lopsided. Yes we wouldn't want users sharing illegal material at the speed of light but in the same breath, it's just a matter of time/technology when one sends a copy of their mini-DVD of their grandchildren and other relatives located far away.
I had to remote assist a person on Comcast once on 384 and 768, it was so laggy/slow redraw I had to dumb down the resolution and color depth to compensate. Yet if I had to remote desktop in from work, I could do it in true color without a worry in the world.
Comcast is trying to play catch up in cities they cannot stop companies like Verizon, but in the same breath ultimately fail. Hey why would I want 16/1 or 15/1 and end up paying more long term than Verizon offers. Especially when their outgoing is twice that of Comcast.
I used to swear by Comcast, but after being treated so poorly then getting two abuse letters that by today's standards would be a drop in the bucket. One has to ask, does any HSI have a leg to stand on? Comcast can up their speeds to keep up and in the process, clog up their networks in certain cities. Then there is FTTP, which is non profitable for the short term and looks bad to investors. Then there is DSL, which is severely limited by distance to a CO or RT. All ISP's have their uncertainties, but in Comcast's case I wish they would invest more in their network than just upping the speeds and hoping for the best. |

| PPPoE is basicly the point to point protocol encapsulated in an ethernet frame (with TCP/IP below that). Because of this encapsulation layer, you actually have LESS efficientcy.
ethernet networks encapsulate data in an TCP/IP in an ethernet frame without any additional overhead. With a fixed MTU size with both meathods your going to get better performance if you not USING PPP (its just an additional layer stuffed into the ethernet payload) .
DHCP has NOTHING to do with network performance.... and is only using for automatic addressing. |

| Hey guys,
Im in LA here, was wondering if anyone can confirm getting these speeds? I was wanting to upgrade to the gamer package, and was wondering if thats a good move here in LA. Im currently in hollywood planning to move to the west side. |
