hello,

i need to understand the bandwidth usage for each RDP client connectting to
remote application server.
i know this value can change from the settings i do on the RDC by i need to
understand the approximative level (min-max).

thank you very much
 
Bandwidth requirements depend on many factors: which applications
your users are running on the TS (graphics intensive applications
like CAD programs are bandwidth killers), how much printing is done,
etc.

Minimum bandwidth for a useable RDP Session = 26.4Kbps
800x600 @16 bit color - 26.4Kbps per session
1024x768 @256 colors - 24.6Kbps per session

each increase in screen resolution or color depth requires about 3-4
Kbps more bandwidth. Printing, flash animations, etc also require a
consideral amount of bandwidth. I would calculate with at least
56Kbps per concurrent user.

I've been doing a lot of testing of ICA Bandwidth used over my WiFi Bridge
and have determined the following:

1. Normal typing in Word, Outlook... uses very minimal bandwidth, i.e.
5-10Kbps
2. Opening apps, maximize/minimize/restore windows... 15-35Kbps
3. Apps that have graphical UI when opening, 25-50Kbps to
open/minimize/restore
4. Flash animation in IE, 50-120Kbps+

These numbers will be similar to RDP, but ICA uses some fancy image
compression (SpeedScreen) and Flash/Video buffering that RDP doesn't do. I
limit my sessions to a maximum of 176Kbps, with 56Kbps designated for printer
bandwidth, so printing of a 100 page PDF doesn't drown my connection or make
their session unusable.

So 26.4-56Kbps are good average numbers to use, but printing,
animation/flash/video/complex imaging can increase this number by several
times, so take thes into account when planning.
