Performance Objectives for Multiple Services in OBS Networks

In this paper, with the representative examples of services, including telephony (conversational audio), HDTV and IP services, according to the parameters from ITU-T Recommendations, we present a series of detailed QoS performance objectives for OBS networks, including one-way delay, delay variation, packet loss ratio and others. We hope that our research could be helpful for the further researches in the QoS schemes of OBS networks.
