Citrix WANscaler

Overview

Citrix' WANscaler product is a hardware appliance that you install on all sides of WAN or VPN links to provide performance improvements - typically of 100-400% or even more.

This means that if you're currently bandwidth constrained, it will give you the ability to push more traffic over the same speed links, and avoid needing to buy more bandwidth from your carrier. If you're currently at the right level, you might be able to reduce your monthly recurring bandwidth charges.

The product essentially finds repetitive patterns within your data, so instead of sending the same data over and over, it sends a "marker" that tells the box on the other side to insert the repetitive data. So technically it's not compression, but the net effect is similar.

Existing bandwidth is also used more efficiently, based on the way WANScaler enhances TCP communications.  Sliding window TCP block sizes are increased from 64KB to 8MB, and latency is improved through better connection management.

Key Benefits

Expand Accelerator provides a number of benefits, including:

• Improved WAN performance, by 100-400%;
• Reduced latency over long-distance connections;
• Improved circuit utilization, reducing inefficiencies;
• Reduced bandwidth costs, a monthly recurring item, provide rapid ROI.
