Gartner Press Release "The worldwide hosted virtual desktop (HVD) market will
accelerate through 2013 to reach 49 million units, up from more than 500,000 units in 2009, according to Gartner Inc.
Worldwide HVD revenue will grow from about $1.3 billion to $1.5 billion in 2009, which is less than 1 percent of the worldwide professional PC market, to $65.7 billion in 2013, which will be equal to more than 40 percent of the worldwide professional PC market."

Desktop Virtualization Refers to the separation of the physical endpoint from
the logical desktop Endpoints may be variety of devices; applications are
hosted where ever the best user experience is offered (locally at endpoint or data center)
Access from the endpoint to the logical desktop is delivered through the network

Borderless NetworkNetwork Strategy
Display protocols are proprietary
Display protocols attempt to deliver media streams, text, and bulk transfer in a single or set of connections
WAAS increases WAN user density from 2X to 8X
Network Intelligence to disaggregate data types so the network can appropriately differentiate
Offer a seamless migration to web
© 2010 Cisco Systems, Inc. All rights reserved. 29
Borderless NetworkDisplay Protocol Channels
Display protocols operate at the session layer
Display protocols were intended to remote applications and not desktops
Desktop interactions require that some local client services be extended to the remote virtual desktop
Channels provide a means to extend remote virtual desktop services
Channels cannot leverage network services like QoS, security, stream splitting, or multicast

WAAS can optimize both VDI (ICA, RDP, MMR, USB) and non-VDI traffic and represents more comprehensive solution
WAAS can be deployed in different form factors : hardware appliance, network module in ISR, IOS feature in ISR, as a software aplication running on SRE module, as a virtual appliance in vSphere. and as an application running on laptop.
WAAS compression ratio and performance is better than most competitor offerings
WAAS licensing is also more favorable and reduces TCO of large scale deployment.
