understanding traffic managment
 
Hi,
Im on 10Mb bb size M, and, my line gets 9.98Mbps. Yet im traffic managed to 1.67Mbps?
Should i expect 2.24Mbps after traffic managment (9.98/4)?

If i got for example 6meg would i be traffic managed to 1.5Mbps (6/4) or to 25% of advertised speed 2.25Mbps (10/4)?

Cable doesn't have problems with distance vs speed. For a 10Mbps package you will get 10Mbps (providing there is capacity in your area of course).

Traffic management kicking in reduces you to 25% of your speed, or 2.5Mbps. If you're getting lower then either something is using the bandwidth or your upstream is too saturated to give the full download. Torrenting etc during traffic management is virtually impossible.

you are managed to the percentage of the advertised speeds

so just like you can get "up to" 10mbit unmanaged (which is pretty much what you are getting now, when stm kicks in you can get "up to" 2.5mbit

no, surely if your on up to 10mb and you get 9.98 then your line is capable to 9.98

when traffic management kicks in, the UBR limits your speed to 2.5mb, you will still be connected at 9.98 but will not be able to use more than 2.5, so you should be getting 2.5 exactly under management

---------- Post added at 18:10 ---------- Previous post was at 18:09 ----------

the OP says they are being limited to 1.67

to clarify, are we talking about the STM or p2p management?

well either, it doesnt matter. Just because he is getting 9.98 doesnt mean that is the max he can get, I believe the config file allows for slightly over 10mbit.

You are not connected at 9.98mbit and only receiving 2.5 if you want to use that logic. You are "connected" at 100bits which is determined by the weakest link in your hardware (probably patch cable), your modem limits you to 10mbit as determined by your config file, and when either stm or protocol shaping is in effect your get throttled accordingly.

Just because you can receive 10mbit which is 100% of your allowed throughput doesnt mean you are going to receive 100% (2.5mbit) when throttled. The whole point behind stm and protocol shaping (allegedly) is to alleviate the pressure on the network during peak periods and if everyone is hammering their connection Friday evenings as an example, you will receive whatever bandwidth is available up to a maximum of 2.5mbit, buuuuuuuuut, that might mean you only get 0.5mbit for a couple of hours.

but just for p2p, the two traffic management policies are separate

General Maximus 29-03-2011 17:47

Re: understanding traffic managment
 
yup, p2p traffic will be throttled regardless of how much you have downloaded

craigj2k12 29-03-2011 18:10

Re: understanding traffic managment
 
outside p2p limiting hours, the stm limited at 2.5mb should be hitting 2.5 exactly.

the p2p varies as all it does is send through p2p as low priority

A quarter of what you pay for

Re: understanding traffic managment
 
If it's not P2P or Usenet then a figure of 1.6 normally means over subscription as the OP is correct it should be 2.5

Just be aware though that traffic management on P2P or Usenet could result in the low figures.,.

More details from the OP are needed (times, type of traffic)

exactly, but still, 2.5 on the stm

p2p management can vary

Its not Usenet or P2P.

An Engineer came last week to adjust my power levels, so, its the UBR? Upgrading my bb would or wouldnt help?

Upgrading your BB would have the effect of giving you more before STM kicks in.
