This paper proposes the emerging Telecollaboration (TC) business system environments supported by Video over IP applications, thus contributing the measurement of user experience. Initially, a simple but comprehensive analytical model for Video over IP is presented for the development of Quality of Service (QoS) indices. We then characterize the model with few illustrative units that provide an integrated context for estimation and mapping of the quality and quantity measures of Video over IP in the ubiquitous Internet. This includes application of Pittsâs software methodology, whilst addressing the second-order network performance statistics in the context of jitter (such as delay and packet-loss variation). Finally at the network level, the behavior of source, queuing, multi-service requirement mechanisms and a set of flows, connections and aggregates are measured to justify the quality inherent usability aspects of video quality. It is expected that the proposed modeling overcomes the degradation of video quality, which is seen as a fundamental problem that often occurs due to the multi-user packet switched network. Our results also suggest that the experimentally validated analytical modeling of Video over IP is of considerable value in promoting the TC initiatives.
