The best way to deliver Cisco’s Jabber® client from Citrix XenApp and XenDesktop is with the Cisco Virtualization Experience Media Engine (VXME). Jabber is Cisco’s flagship Unified Communications client, supporting presence, instant messaging (IM), desktop sharing and audio-video conferencing. The key to delivering Unified Communications clients like Jabber at scale in a desktop virtualization environment is to offload the media processing to the user device whenever possible by installing a media engine alongside the Citrix Receiver. Video processing is particularly CPU-intensive so offloading it from the XenApp/XenDesktop server to the user device is a great boost to user density. This optimized architecture also ensures that there is no degradation of audio-video quality since it avoids “hairpinning” (a.k.a. “tromboning”) of the media traffic through the XenApp/XenDesktop server. The only traffic to go over the ICA virtual channel between the Jabber client and the VXME is signaling information; audio-video traffic travels peer-to-peer between the user device and the other party to the call or to the conference bridge in the case of a multi-party call.

The Cisco Virtualization Experience Media Engine works with Jabber for Windows 10.6.1-10.6.x to enable users to send and receive phone calls within virtual/published desktops. The VXME is a Citrix Receiver plug-in that detects the virtual environment and locally routes all audio and video streams directly from one thin client to another or to a telephone, without going through the XenApp/XenDesktop server.

Cisco has just released version 10.6 of the VXME for SUSE Linux and Windows. This new release supports the entire Dell Wyse SUSE Linux thin client portfolio and brings alignment between Cisco’s SUSE Linux and Windows platforms. In response to demand from our mutual customers, Cisco has expanded OS and thin client model support in this release. Deployments have been rising significantly over the past several months as organizations are virtualizing their environments at an accelerating rate. Cisco and Citrix have collaborated closely to ensure that VXME supports the latest Jabber capabilities and delivers an uncompromised user experience.

Here are some highlights of the new 10.6 release, courtesy of Sandeep Prasad, Product Manager at Cisco for the VXME:
