Key Points about F5 Citrix Solution
 Loadbalancing XenApp and XenDesktop
–
–
–
Pre-built deployment templates and deployment guides for XenApp and
XenDesktop
TCP optimizations and SSL offload improve user experience and provide server
offload
Provides High Availability to Web Interface and XML broker infrastructure
 Remote Access to XenApp and XenDesktop
– Transparent implementation that requires no special Gateway Direct
configurations
– Single policy and configuration setup, and SSO for all clients: desktop
ICA, PNAgent, Receiver
– Eliminates the need for Secure Ticket Authority for remote access
– Eliminates the need for Citrix Access Gateway for remote access
– Removes troubleshooting complexity and consolidates all remote access
troubleshooting to a single point only – F5.
– Accelerates ICA data delivery of WAN links

Optimizing ICA traffic for WAN users
• F5’s unique TCP Express stack is key to offering best
possible TCP performance on the market.
• ICA protocol is TCP-based – thus it most directly benefits from
TCP Express optimizations
• Customer testing showed F5 ICA proxy be able to sustain
near full T1 link utilization for a single ICA connection with 200
ms latency and 1% packet loss.
