WAN Optimisation

An integrated approach to delivering optimized performance

A customer’s Wide-Area Network (WAN) is the foundation of their globally connected enterprise, enabling collaboration, communication, business productivity, and risk mitigation. The performance of their WAN is critical to everything customers do. With WAN Optimization solutions, their business runs faster and more efficiently, delivering consistent service levels and cutting the costs of their IT infrastructure.

Since their WAN is fundamental to so much of our customer’s business, WAN optimization can deliver massive improvements to a wide range of their top IT initiatives:

• Accelerate application performance up to 50X, increasing business productivity.
• Consolidate in the branch and datacenter, and see a 6-month payback.
• Optimize file sharing, web, email and even voice video – all at the same time.Leverage cloud economics without compromise.
• Protect data more completely, with less cost and effort.
• Solve problems up to 83% faster.

VoIP and Citrix
 For some companies, it is a priority to ensure adequate performance for key applications that require a fixed amount of WAN bandwidth per user. Popular examples are Citrix and VoIP, both of which can require about 15 kbps of designated bandwidth per user.

By deploying appliances on your WAN, you can reduce the bandwidth consumed by your enterprise traffic, by 60-95 percent, which can make room for other bandwidth-intensive applications. If you have 40 users in a branch office using VoIP, they might require 800 kbps just for VoIP, and perhaps another 750 kbps for other network traffic. If you have a T1 (1.5 Mbps) of bandwidth to that office, then as you add users, you’ll be forced to upgrade that link. With WANOptimisation appliances, you might be able to reduce the other data traffic from 750 kbps to 150 kbps, or even less, which lets you expand without adding bandwidth.
WANOptimisation solution can also optimize the traffic associated with delivery of virtual desktops for Citrix. This is simply enabled by automatically switching to WANOptimisationsolutions’s compression and encryption in place of the less effective native compression and encryption options in the VDI products. Also WANOptimisation solution’s data reduction can be performed in memory to efficiently reduce the bandwidth requirements giving high throughput results. Typical results show that up to twice as many desktops can be supported on the same WAN (by halving the bandwidth requirements of each), and end user response times can improve by up to 80 percent (over uncompressed traffic) making for more satisfactory performance. Further, Citrix desktops can be optimized utilizing QoS markings, to prioritize interactive activities like desktop input and display over less time sensitive operations such as printing.
