limitting bandwidth?

is there anyway to limit bandwidth?

i am experimenting with different video codecs to stream over the internet and i would love if i could have control over my download speed.

i want to run tests at 56k, 128k, 300k to see how different video streams.

any ideas?

That is if it's a Linux firewall you're running.. have No idear how to do it in windows..

well, Im nobody, but I would suggest that if you are a cable\adsl subscriber; to at one point unhook from dsl, and use your reg, modemn for 56k, compare that with your reg. download. As for the speed 300k, well that would probably be only on a good day anyway.. I don`t know but let me know what you come across...

i think he means streaming out....

mmilano, ive been looking for something like that myself. Let me know if you find anything

do people still have "56k modems"?

hehe, i sure don't . . and if i did, i don't think i'd want to pay for the dial up service .. umm .. now to think of it, i don't even own a lan phone line. cell and dsl is all i need for communication =)

i haven't found anything yet rev, .. i haven't really looked too mucheither though. it would be a cool thing to invent.

it doesn't seem like it would be that difficult for someone who knows about network programming.

well we laugh at 56k, but yet still want to test video stream. So why test it, but in Ukraine those guys are still working with slow speed. Soo lets not laugh yet... ; Until the whole world catches up,, later

yeah, for the video i'm testing, i pretty much can't render for 56k because of the length of the movies, .. but i can optimize it to stream for 200-300k .. my cable line gives me 2mb+ , so it's hard to see how it will stream for people using dsl with a 256k download.

i do develop web sites and i develop for lower bandwidth, but for the video i'm doing, i don't really have an option, unless they want to wait all night.

mmilano, you have cable internet? What type of machine do you have, That sounds like good speed.

id say no; the medium you use determines how fast your bandwidth is... you could *slow* it down at the application level by just not processing it as fast but that'd just be stupid; id suggest its not possible via a program u would need a physical limiter connected to ur nic and ur connection medium

yes i have cable, even though i get over 2mb down, it's only 128k up. it's a p4 1.7ghz, .. but that doesn't really have anything to do with the speed of the conection ..

i think you're right abc, .. i wish someone made a box with a dial that i could turn to cap the bandwidth .. but then again, i probably wouldn't want to pay for what they would charge for it too.

Mike,

Check in your Virtuozzo VE under services / iptables. You *may* be able to do something there, but I am not sure.

What you are looking for is a traffic or packet shaper that will impose limits on bandwidth transfer. It can be done at the server or client (for simulations) but I'm not real sure exactly how in a UNIX or Windows environment, only at the router level.

But it *can* be done. If the iptables doesn't do it, I can do it in the hardware node of the VE, but then it wouldn't be under your control and hence worthless.
