Cisco WAAS deployment over VSAT WAN links

[Christopher Kofon]

Hi.

I would just like to know if you can implement Cisco WAAS on a WAN running on 128 VSAT llinks and if the performance improvement will be very significant. Significant enough to make me change my mind from upgrading the link?

Thanks

I think the answer is "it depends."

Assuming you have high latency of 500ms+, then any WAN accelerator will help dramatically with email, FTP, cifs, etc due to tcp optimization and compression at least. However, realtime traffic such as voice will not benefit due to already encoded data using udp.

Hi Tod.

Thank you very much for your reply. It was very helpful. I am currently researching into the viability of Cisco WAAS as an optimization tool that will increase bandwidth and reduce costs. I wanted to know if you could help suggest any useful document that could help in my research.

Thank you again.
