bandwidth requirements for terminal server and PDF

Hi List,

Those of you using terminal server (specifically Win2K terminal services
without Citrix) what is your opinion on a safe estimate of bandwidth usage
per user ?

Generally it seems to be 10-12 Kb/s per user dependent on the usage that is
suggested and JD Edwards seem to add a little safety and suggest 12-15 Kb/a
per user - has anyone got any tangible measurements of their bandwidth usage
?

There have been various threads on the list over time on the amount of
traffic generated by PDF output - do you think that the figures quoted above
are inclusive of the estimated PDF traffic or should this be allowed for
separately ?

Be grateful for anyone's experiences with this.

Regards

Andy :

It depends on :

a) Screen resolution and colour depth. Try to use 16 or 256 colours modes,
and 800x600 seems to be the optimal resolution. If you stick to these video
modes, 10 or 12 kbps should be enough.
b) PDF printing. Printer traffic is WAN intensive, dedicate at least 15 or
20 kbps for Printing output, if possible don't use print resolution above
300 dpi, the better the resolution, the larger gets the spool file that will
be transmitted.
c) Screen interaction. These technologies rely on screen caching, if the
user always goes to the same couple of screen the WAN performance will be
better that if keeps jumping across dozens of different applications.

Andy,

We use 15K per connection as our standard. This has come from measurements from the US to Europe/Asia Pacific, over the last 2 years.

As far as PDF traffic, I presume you mean print traffic. We do not allow the users to print from Adobe (Citrix). We force them to use JDE's print button, and route the printing through our AS/400. This allows us to prioritize the print traffic to just above Web traffic. Otherwise the print traffic travels as Citrix. (True story: I have received help desk tickets with the comment 'It takes a long time to print 4000 pages', this ticket came from a remote site in Europe, they were printing on a HP 4Si)

Our prioritazation scheem is: 1) Citrix traffic; 2) Other traffic; 3) Print traffic; 4) Web traffic.

Alternatively, if you wish to prioritize packet types across the network - Packeteer (http://www.packeteer.com) provides products that were tested long ago with JD Edwards. The best use of a packeteer unit is to prioritize Citrix packets above print packets - which can be performed since they are on different ports.

Hi.
I test printing from WTS (NT4 TSE), but all results in russian (See attachment file):

We use Citrix Metaframe.
