Linking media servers & course management systems

Dynamic Class-Based Queue Management for Scalable Media Servers

Real-time media servers are becoming increasingly important due to the rapid transition of the Internet from text and graphics based applications to multimedia-driven environments. In order to meet these ever increasing demands, real-time media servers are responsible for supporting a large number of clients with a heterogeneous mix of Quality of Service (QoS) requirements. In this paper, we pr...

Minimizing Memory Requirements in Media Servers

Poor memory management policies lead to lower throughput and excessive memory requirements. This problem is aggravated in multimedia databases by the large volume and real-time data requirements. This study explores the temporal and spatial relationships among concurrent media streams. Speci cally, we propose adding proper delays to space out IOs in a media server to give more room for bu er sh...
