View Full Version : Avoid Traffic Management
Worked this out earlier today and thought it would be fun for others to give it a go.
If you download more than 3Gb between 4pm and midnight (XL BB) you get capped to 5meg speeds.
What speed would you have to cap your downloads to, to avoid being a victim of traffic shaping?
lol vm will love you when you phone support my guess is less then 3gb (do i win a prize).
grats btw your one of the lucky people if you can manage to download 3gb between those times.
what would your maximum speed have to be?

He means what do you have to cap your actual download speeds to to not be capped through those 8 hours.
It's too much maths for me right now to work it out, if someone doesn't come up with an answer I'll answer it later.
Oh, and are you on 10mbit or 20mbit?
you would have to limit it to 750kbps download and it should be done by traffic shaping hours play it safe so around 60-70k download would do (theres the speed you guys are LIMITED too during traffick shaping hours in vm eyes:)).

109 kilobytes/sec
3gb over 8 hours=
3072 / 8 = 384 meg/hr =
384 / 60 = 6.4 meg/min =
6.4 / 60 = 0.1 meg/sec =
0.1 / 1024 = 102. (109.22666666666667 without the rounding)
:clap:
which, if my sums still work out, is just over 4% of your available bandwidth :Yikes: (20meg)
(500 Posts) :) [not any more] :(
If you are interested though, if you ignore the traffic shaping you can download a total of 21.66 gig between 4pm and midnight)
(3 gig at full speed in the first 21 mins, then 8.58 gig over the next 4 hours, and then 3 gig at full speed again, and then 7.08 gig over the remaining 198 mins until midnight)

Considering even the 2 meg when STM'd allows 1meg down your figures are rather unrealistic.
If you're saying thats the speed you'd have to limit yourself to to avoid being STM'd then whats the point? Why bother throttling your own speed for 8 hours, in an attempt to avoid STM ,to a lower speed than STM gives you anyway? You're better off getting STM'd

Gavin, by those figures there is a higher probability of being STM'ed for up to 12 hours, depending on what time before midnight the last "over 3 GB" occured.
Hey listen daffy someone here asked what speed you would have to download at WITHOUT triggering the stm thats the speed unrealistic or not.

I obviously misunderstood your post so i apologise

Hi.
This is an interesting subject (although it has the hassle factor of having to think twice about various references - but more on that later, when I indulge myself in a little pedantry...)
The daft thing is that I, in a knee-jerk response, was limiting myself to a 60 kBs download speed for 5 hours, to avoid being capped to 305 kBs for five hours: I've since worked out that I'm better off leaving it to run wide open.
But there is just a hint from VM of more vicious reprisals if the TM limits are not observed, or habitually ignored. (Will they send a SWAT team to smash my modem?)
Now to the nit-picking.
"If you download more than 3Gb between 4pm and midnight"
Firstly, it's GB, not Gb.
Secondly, it's 9.00 p.m., not midnight.
I know, it's the thought that counts, not the numbers,
but reading the posts on this board (and others) shows an almost universal ignorance (or ignoring) of the correct abbreviations: people seem to happily swap their b's and B's, m's for M's, their g's and G's... It's important!
For example:
Someone asked "are you on 10mbit or 20mbit?".
Assuming this is a reference to speed (eg 20 mbit per second) at that speed it would take around 450,000 hours - 51 years - to download a typical 3.5 MB mp3!
k = kilo = x thousand
M = mega = x million
m = milli = thousandth (ie, 1/1000)
Moving on:
b = bit
B = byte (In general terms, and for this discussion, 1 byte = 8 bits)
So,
mb = millibit 1/1000 of a bit (if ever used, other than by mistake)
kb = 1000 bits
Mb = 1,000,000 bits = 1,000 kb
kB = 1,000 bytes (approx 8,000 bits)
MB = 1,000,000 bytes (approx 8,000,000 bits; 1,000 kB)
And so on...
A big grumble I have about VM so-called "Technical Help" is the way they all seem to mix up their megabytes with their megabits - this very morning, someone was telling me that my service was a "Ten megabyte broadband connection..." I wish! In other words, they don't know what they are talking about!
If we don't use the correct terms, we will never be able to seriously argue (or discuss) any service issue we may have.

:welcome: to the forums. :)
Totally agree about the units thing!
The original post was from 2007 though, so at that time 4pm to midnight were the hours involved. VM have since modified them...

PS to above:
“someone here asked what speed you would have to download at WITHOUT triggering the stm”
According to my calculations (best to check it for yourself), for both up and down,
To Reach: 200 MB in 5 Hours, the approximate Rate = 11 kB/s
To Reach: 500 MB in 5 Hours, the approximate Rate = 28 kB/s
To Reach: 700 MB in 5 Hours, the approximate Rate = 39 kB/s
To Reach: 1000 MB in 5 Hours, the approximate Rate = 56 kB/s
To Reach: 1200 MB in 5 Hours, the approximate Rate = 67 kB/s
To Reach: 1400 MB in 5 Hours, the approximate Rate = 78 kB/s
To Reach: 2000 MB in 5 Hours, the approximate Rate = 111 kB/s
To Reach: 2400 MB in 5 Hours, the approximate Rate = 133 kB/s
To Reach: 3000 MB in 5 Hours, the approximate Rate = 167 kB/s
To Reach: 6000 MB in 5 Hours, the approximate Rate = 333 kB/s
So to avoid being capped, stick below these rates. But remember: to limit yourself to, say, 60 kBs, for 5 hours, will avoid being limited by VM to 305 kBs, for 5 hours (10 Mb connection).
Cheers,
s.

Hi, again - Oops - didn't notice the 2007 thing - I just saw the 05-07 part.
Oh dear.
s.
i'd like to nit pick a bit,
mbit & mbps don't follow the m = milli standard, they've always both meant megabits per second.
secondly, VM technically offer 2.048mbit, 4.096mbit(10.24mbit), 20.48mbit services
finally, i expect VM's limit is actually 3GiB, ie, 3221225472 bytes not 3000000000 bytes :p:

Hi.
Good points. (And nit-picking is always fun! :)).
I was trying to generalise (without being too general - and avoiding the differences twixt transmission and storage terms, etc.).
I agree that m can be (and is) often accepted to indicate 'mega' (I mean - who ever heard of a millibit, anyway?) but in the interests of general uniformity (most ISO standards regard m as meaning 'milli') I prefer M for mega. (My main grumble is the use of b for B, and vice-versa.)
As for, eg, 3GiB being 3221225472 bytes not 3000000000 bytes, I think I used the word "approximately" often enough... However, VM don't use the term GiB in the TM thresholds and limits.
(Yikes - let's not get into bibits, Kibibits or Megabibytes...etc. I reckon that most people - and my old brain - are confused enough as it is. I've had to drag my mind from the sink of Bauds! :dozey:)
Regards,
s
I love this unit pedantry. Thing is the GB is so commonly used (eg by an OS) when they really mean a GiB...

Apart from using a DL meter is there a clever way of limiting downloads speeds using windows or some other settings for the network card?
The reason I ask this is that I'm interested in a rock steady gaming ping not affected by third party STM traffic interrupts.
Guys (and girls), ive done all the maths for you- its here in this thread
http://www.cableforum.co.uk/board/12/33634678-stm-rates-vm-expect-you-keep.html
For the OP on XL, during the evening its 1.33 meg or you trip STM.
