| Research Abstract |
We developed mathematical models and performance analysis methodologies to evaluate the quality of service (QoS) of large-scale content discovery and delivery systems. In terms of those models, we evaluated the transmission delay and packet/frame loss probability as performance measures. We also evaluated the effectiveness of packet-level forward error correction (FEC) which plays a key role for quick recovery from possible packet losses caused by buffer overflow and transmission error while carrying real-time traffic and one-to-many traffic.
