*Just* based on what you've told us, two things:

1. Depending on the applications (i.e., Citrix vs. non, file transfers, etc.) 512K doesn't sound big enough for 30 users. If they're ONLY using Citrix or SAP or something, maybe 512K will work.

2. My first suggestion is to look at a 2811, again, depending on how the 512K is delivered, etc.

Hi ptrivino,

The applications are: RDP (termianl services), file transfers, smtp; but the priorty is RDP.

2801 should be a option? is the smaller?

Here's a thread I found on RDP bandwidth requirements - http://support.citrix.com/forums/thread.jspa?forumID=90&threadID=68787&tstart=0 - which is good, I never knew myself.

So, if you can set it down to 26K, times 30, is 780K. If everyone is on at the same time, you're already 50% oversubscribed.

And sure, a 2801 is fine too, just depends on how much interface expandability you want.

I've between 12 and 18(20 max) RDP connection, but for the channel also pass a SMTP, file transfers, etc. I want to give priority a RDP traffic and VoIP (two channel for now).

You think that the model 2801 can do it?

Thanks again

I am very confident that the 2801 can handle that workload. My only concern is the BW available - 18 RDP sessions still eats most of your 512K. Figure VoIP bandwidth for 2 calls at G.729 is still *around* 50-100K (depending on what type of WAN ckt), it's a tight squeeze.

But if 512K is what they gave you, just be prepared to monitor the BW usage closely.
