摘要：
As advanced Internet services, networked virtual reality (NVR) applications impose certain quality of service (QoS) requirements, due to rich multimedia content and perceived "real-time" interactivity. Two different representations of QoS are needed at the user/application level and at the communication level, which our approach attempts to relate using as a reference an interconnection model for NVR applications. We present the design and development of a multi-user virtual audio chat application and a performance evaluation based on QoS requirements. Objective and subjective methods for determining QoS have been addressed, and our results analysed for the purpose of possible QoS improvements. (C) 2002 Elsevier Science B.V. All rights reserved.
