ATIS - Alliance for Telecommunications Industry Solutions
Scope
"Scope Purpose Telepresence enables people at different locations to communicate with each other in an experience that is as close to ""face-to-face"" as possible. Originally@ this service was implemented in an intra-service provider (SP) (single administrative domain) at the business level. This intra-SP success led to telepresence on an inter-SP basis@ delivered across multiple domains/multiple SPs via dedicated pipes@ bilateral SP agreements@ or various networks. To enable a successful telepresence experience in this expanded environment@ many aspects related to telepresence planning need to be considered. Two critical aspects are: Telepresence Quality of Service (QoS): End-to-end performance parameters that focus on the IP transport from the underlying networks and enterprise segments impact the service QoS. These parameters are IP Transfer Delay@ Delay Variation (Jitter)@ Packet Loss@ and Errored Packets. Telepresence Quality of Experience (QoE): Service level parameters such as video frame loss that impact the actual experience of the service viewers. The purpose of this ATIS Standard is the evaluation and recommendation of the QoS and QoE aspects of telepresence described above. The scope of this ATIS Standard is the examination of these QoS and QoE aspects@ and the development of interworking requirements to support desirable levels of telepresence quality."
