ICA vs RDP over a WAN

[Patrice Lévesque]

Hi there,

Is there someone who can convience me than the ICA protocol is more
effecient than using the native RDP protocol of Windows NT 4.0 Terminal
Server, over a WAN using a Frame Relay Network of 128, 254 and 512 kbps,
depending of the remote sites.

Thanks in advance.

ICA seems to be the better protocol, but not for an obvious reason. Both
seem to use approximately the same amount of bandwidth during normal
usage - ICA might use 1-2k less.

However RDP "bursts" reasonably often, ICA is hard-coded not to burst
over a certain rate of bandwidth, I believe is 18k or around that figure.

I guess you've got to weigh those things up, and then decide if MetaFrame
is worth it....

Cheers
Nathan

Citrix used to talk a lot about how much better ICA was than RDP, but this
talk seems to have subsided. Who knows why - a cynical person might say it
was pressure from their "partner", Microsoft. Microsoft claimed they were
going to make RDP as efficient as ICA in the production release of WTS. I did
not test the beta, but I heard it was a dog compared to ICA.

In any case, some features of MetaFrame such as compression and bitmap caching
should make ICA faster even if the bandwith is is the same (~20k). For me, the
other feature of the MetaFrame client such as client side drive mapping and
printing also make it a worthwhile addition to WTS.
