One concern that a member of the audience had with VDI was how much bandwidth it consumes. Citrix's Cockerill responded that bandwidth isn't too much of an issue.
"We've done some testing and to do an average hour's work with opening apps and maybe looking at video, running XenDesktop at 1280x1024 will consume about 15 kbps," Cockerill said. "The bandwidth consumption of our ICA protocol is very low and we keep optimizing it."
VMware is working on similar bandwidth optimization techniques. Chen said that in the second half of this year his firm will roll out new WAN optimization technologies for VMware VDI products.
The effort will revolve around ensuring that the only items that are refreshed on the user desktop are the items that change.
Red Hat is in a similar position where they are working on optimization technology.
"What we've done over last 6 months and will continue until we launch later this year, is adding in compression and tuning," Ferris said. "We're aware of the issue and it's been the number one focus for us."
While optimization may be coming to all of the VDI vendors, one thing that isn't in the cards anytime soon is standards for VDI.
"I can't see standardization any time soon," Cockerill said. "That's a big part of our differentiation and how we deliver the user experience."
Red Hat's Ferris though has his own ideas on how standards might potentially evolve.
"At Red Hat we're big fans of open source," Ferris said. "Open source could help to establish standards."
