Here is what I've found using ICA and Citrix. Haven't done testing with RDP but my guess is that the numbers will be a bit larger: An average ICA Session using Office products (Excel, Word and Outlook) and an Oracle database, average session bandwidth is 10K with the minimum being 0K (idle session) and bursting to 100K+ during login and printing. This was done taking 1 minute average and 1 minute peak for the ICA connections. What you really need to do is monitor your RDP connections using a monitoring device (PacketShaper) to determine how much bandwidth (minimum) is required to establish, maintain, and guarantee the connection to Term Server. You probably don't want performance to suffer in a DR scenario. With Citrix ICA: 400 Connections * 10K per connection = 4MB bandwidth + 500K for printing and overhead (DNS, WINS, ICMP)...3 T-1's? If the bandwidth is not controlled, then this formula doesn't work.

I'd love to know. Thanks. DB. 1 Average User : Total Bytes : all for 60 min period. Min 0 Max 1976 Average 259 1 very active user Total Byte : 60 mins... Min - 0 Max -27058 Average - 1278 ---------------------- I'm doing some DR research.. I'm trying to workout how much bandwidth my RDP users are utilising - 400 of them.. so I can cost up another pipe (leased line) into another building for DR resilience. I'm taking the default application that the users use and have been monitoring (with perfmon) the performance object "terminal services Session" and selecting the "total bytes" counter for all the instances. I monitor the users for 1 hour slots .. Should I be looking for some other counters ?.. All the documentation I've read seems to indicate that RDP is more hungry than ICA.. but the average user is using 2Kbps and my manic power crazed guinea-pig tester (me) can only get to 10Kbps average .. I'm using the remote desktop client (from a win XP client) with full screen and bitmap caching turned on.
