Virgin's 50Mb broadband arriving December 15? - Page 13

does COD 5 use tcp or udp for its data exchange,and at what average rate ?

torrenting at 92Kbit/s still leaves something like 75/80Kbit/s for random single person web browsing, if thats pulling CF type pages, thats plenty for allowing full return Acks. assuming the new 1.75Mbit upload rate and the UBRs/cards not over subed yet

and OC VM are going to allow small (or perhaps not so small right now)micro bursts well above the set rate in average trial usage....

downloading and uploading at the same time (torrenting) would have a negative effect on the speed though.

as per the ratio i spoke about above, you take them both in to consideration, we are talking about the used upload rate here, due to the download rate being far higher OC....

unless the torrent download, the COD5 AND the random web page pulling were anywere near the 48/50Mbit download rate at the time, then we are only concerned with the used upload rate, if its within the set rate for the average time then download will not be effected from the CM/UBR POV.

the VM techs and people that only see the 50Mbit/s headline without understanding the requirement for ballanced upload ratio, were insisting that the old 1.5 Mbit/s upload rate was good enough to pull full 50Mbit/s tcp downloads, and good enough for them as they dont upload

(you do ,every time you pull something using tcp)

its not good enough for 50Mbit/s download, as maxing out the download will require 1.87Mbit in return tcp ACKs....

its got nothing to do with torrenting as such , you could use UDP for torrents and remove most of the tcp ACK ovehead for instance, its everything to do with using any TCP related apps to the max speed your package is allowing you to use and pay for and the ACKs that requires in upload rates.

is the 1.87 figure involving ack supression? seems a little high.

popper · 12-12-2008, 22:51

back of the envolope generic windows ack settings, and ethernet frames, not allowing for any special settings or overhead in cable DS additions to the frames or any other potential additions , generic ethernet best case to be fare....

Roll on 2009.

Could not agree more!

they have no idea when it will be and the one was from techincal support
think he was from secondline support as he knew more that the usual people
that answer

There will be a big fanfare on Monday.. So not alot of people in VM know about it yet.. However it was made viewable from internal intranet sites on Friday.

Absolute Tosh! There will be around a dozen areas launched this side of Christmas then up to 50% of areas in Q1 then remainder by beginning of Q3 09.

The Beeb seems to have a low opinion of VM's Warrington customers.

"The service will be rolled out throughout 2009 and it is thought that Warrington will be the first place to be upgraded because of the density of Virgin customers in the area."

Roll on tomorrow thats all I can say

Lets hope Hemel Hempstead (Luton UBR) is not left till last.........

I need my 50MB FIX!!!

(Anyone with the low down on the rollout, a PM would be nice

)

If they follow the 10Mb rollout plan then Luton was about 3/4 way down the list

Zhadnost · 14-12-2008, 12:01

Well hopefully we will see the initial rollout plan tomorrow.

C'mon Southampton (something I've never called before).

General Maximus · 14-12-2008, 12:01

that is what I am worried about as well. Lincoln was about 2/3 of the way down as well. It would be nice if they did the people who were last last time first this time just to make things fair.

I saw that earlier...and now it's gone from the BBC Technology page (but still accessible from the above link). Maybe someone at Virgin saw it and told the Beeb to take it down?
