Telepresence Test Solution

Telepresence’s success is based on the ability to conduct live meetings, from remote sites, over IP networks. Telepresence is feature rich, one of these features is the ability to stimulate the attendees senses, by the delivery of high quality video and audio components.  More sophisticated systems go further to deliver a complete in the room presence or sensation.

Testing Telepresence is a complex challenge, especially if the goal is to measure each and every individual end-points Quality of Experience. A suitable solution for these complex multi-flow tests is diversifEye. At a minimum each Telepresence end-point has 4 unique flows; video in - out and audio in - out. Today, diversifEye is the only test solution available  that provides stateful emulation of Telepresence end-points with performance measurements on each and every associated flow.

Telepresence Interoperability Protocol (TIP)
Included in diversifEye's Telepresence test functionality is the industry's first Telepresence Interoperability Protocol (TIP) testing suite. diversifEye's enhanced product line offers multivendor Telepresence customer end point emulation and quality of experience analysis.

Shenick's software offers the first opportunity to test TIP, covering signaling and media for HD/SD video, voice and data. Shenick diversifEye measures performance and quality of experience (QoE) on each and every TIP client in real time.

Telepresence Infrastructure testing
A successful Telepresence meeting is reliant on zero media faults and zero network interruptions. Telepresence utilizes high quality audio and video flows, the multiple flow approach per end-point is a key aspect to Telepresence.

When selecting Telepresence infrastructure the selection of the management system, the end-point codec type and network link performance are crictical to the success of the deployment.

Meetings begin when a multiple of individual end-points connect to a central meeting management server. These servers manage many aspects of the call including the video and audio distribution. However, prior to commencing a call the unique remote end-points need to authenticate usually through a SIP registration server. Other components in a Telepresence deployment include meeting schedulers. The following is a sample of the test functionality required when testing Telepresence:

•  Stateful: Test end-points must communicate with 3rd party servers
• TCP/UDP Aware: Capable of negotiating network control signals and requests
• SIP Aware: Respond to SIP protocol requests
• Application Aware: Test end-points should receive and transmit video and audio i.e. (4 x media flows)
• Per flow Aware: Measure performance on each of the associated voice and video flows
• Codec Independent: Test end-points can use a number of different codecs
• Multiple Clients: The number of test points needs to be scalable

 
Shenick's diversifEye is the only solution available today enabling testing with such granular functionality. diversifEye's per flow architecture enables emulation of not one but many stateful, fully interactive Telepresence end-points which are network and application aware.

A critical feature to testing Telepresence (provided as standard in diversifEye); is the ability to measure performance on each and every one of the 4 unique media flows associated with each and every emulated test or end-point.

diversifEye's emulated Telepresence end-points can join real or live meetings and measure performance on all available media flows. In addition, diversifEye may be utilized to inject traffic into the system in a bid to disrupt the meeting, further testing the security and reliability of the deployment.
