Abstract
There has been an increasing need to make the Internet architecture capable of meeting the diverse service requirements of newly emerging applications such as multimedia conferencing and e-Commerce. This thesis addresses the following question: Is it possible to deliver latency-sensitive applications (LSAs), e.g., streaming audio and video, with satisfactory quality of service (QoS) in large-scale network without compromising scalability and bandwidth efficiency? We have proposed an innovative distributed control architecture, the Clearing House (CH), and a set of adaptive mechanisms to address these issues. Our design rationale is influenced by discussions with two major U. S. Internet service providers and driven by a realistic model of application-level performance requirements. Towards this end, we focus on Voice-over-IP (VoIP) as an example workload and perform subjective experiments to quantify the impact of packet losses and delays on perceived voice quality. Our results show that packet loss rate should be below 1% and per-hop delay should at most be 5 ms to 2 guarantee high-quality VoIP delivery.
