data pipe - how many users?


Assuming a decent amount of RAM, how many users could a 10240kbps data pipe support if they were mainly streaming video through a proxy server?

10240kbps data pipe at the data centre.
"Up to 10 Mbps virtual data pipe just like having your own leased line."

Hi qwertyjjj,

I don't think this is something that anyone can tell you, you would need to profile the usage. A few things that would affect your calculations could be -

Are any of the streams multicast ?
Can your proxy handle streaming media ?
If your proxy can handle streaming media, how much of the content is revisited ?

Sorry mate, no easy answer

cheers,

kbp

Just looking for a rough guide assuming all users were streaming data all at once. I realise in real life they will connect at different times to different sites, etc.

They might be multicast, I don't know the broadcaster's setup.
The proxy can handle streaming media as long as it is not caching. Caching makes it rebuffer too often.
Some of content might be revisited but many people go to different sites so not all watching the same thing.
These sites have live streaming for sports but stored video for old programs which can be requested on demand at any time.

I guess I could load test it but that's more for individual HTTP requests isn't it?

If you ran a load test with all unique streams that should give you the worst case scenario of max simultaneous connections, wouldn't it ?
