We have recently begun a project to support off-shore developers through VDI. The developers will be coming from overseas through a VPN to a third-party data center in southern U.S., then using the View Client to attach to their VDI instance. I was asked the recommendations on bandwidth for their connections, but haven't been able to find anything concrete that states something along the lines of "for best user experience you should have x-level connectivity or xMBps". Also of concern will be latency. Does anyone know of any technical guides for this information?
Page 19 of this doc has some starting points. It's on Cisco's site, but it's from Teradici. Your mileage may vary.
