Abstract

Real-time media streams with (m,k)-firm are increasing and attractive as it proposes an alternative quality of service (QoS). In order to meet these ever increasing demands, the problem of scalability should be considered under limited resource. The problem is ignored in the existing solutions all along, because these solutions maintain a separate queue for each stream and per-stream state information. In this paper, we extend the work made in[Ji Ming Chen, Zhi Wang, Ye Qiong Song, and You Xian Sun. A scalable approach for streams with (m,k)-firm deadline. In Proceedings of IEEE Workshop on Quality of Service for Application Servers (2004 October)] and propose loss-rate balance (static) and stream number balance (dynamic) Class Selection Algorithm (CSA) for real-time media streams with (m,k)-firm, which is scalable while offering dynamic performance close to that of existing solutions. The effectiveness of static CSA (S-CSA) that captures the trade-off between scalability and QoS granularity is evaluated through extensive simulation studies. It is also shown that the S-CSA is as effective to guarantee QoS in terms of dynamic failure rate as the dynamic one.
