Wyse Launches Virtual Desktop Accelerator (VDA) To Deal With Latency on RDP/ICA Connections (?)

Thursday, 09 July 2009 by Michel Roth

Wyse has launched the newest addition to the TCX famility of products: Virtual Desktop Accelerator (VDA). It should be able to imporve the user experience of RDP and ICA sessions for users connecting over a (pretty bad) WAN.

Wyse VDA addresses limitations of existing data centers, which are currently constrained by proximity. Today, an application or service, hosted and delivered from data centers is typically within 100-300 miles of the end-user recipient. Without this proximity, the user experience suffers from network latency, packet loss and other inefficiencies found in longer networks. Because of these issues, businesses are forced to maintain multiple data centers to handle all geographies. Wyse VDA virtually eliminates these geographic constraints by accelerating network protocols up to three times in order to greatly enhance remote end-user productivity and experience in virtualized settings.

Wyse Virtual Desktop Accelerator will accelerate popular virtualization architectures such as Citrix® XenApp™, Citrix® XenDesktop™, VMware View and Microsoft Terminal Services.

Wyse VDA addresses challenges faced by companies attempting to use cloud computing or virtual clients located around the globe but find the user experience unacceptable due to network distance. Working without specialized hardware, Wyse VDA complements existing remote desktop protocols, including Citrix® ICA®, Microsoft RDP, and VMware View ,accelerating the experience to LAN-delivered levels. By reducing the impact of network latency, Wyse VDA eliminates the sluggish performance often associated with virtual desktops connected to remote data centers or public clouds. Remote users will, for the first time, experience the same level of network quality as local users. These benefits also extend to local geographies, whether end users are located only a few miles from a data center, are in the next state or the next country. Latency and packet loss inefficiencies are mitigated without any impact on end user experience. Wyse VDA also can help enterprises with business continuity and in disaster recovery scenarios. In standard operation scenarios, end users are located close to the data center. With Wyse VDA, if those data centers are in a disaster situation, the enterprise can easily connect the effected end users into alternate data centers without compromising their experience. Wyse VDA does not interfere with the security and encryption of the underlying remote display protocols. Wyse VDA works standalone or as a compliment to existing hardware WAN accelerator solutions adding value to customer deployments by providing acceleration specific to remote desktop protocols.
