Building MEMS-based storage systems for streaming media

MEMS-based Disk Buffer for Streaming Media Servers

The performance of streaming media servers has been limited due to the dual requirements of high throughput and low memory use. Although disk throughput has been enjoying a 40% annual increase, slower improvements in disk access times necessitate the use of large DRAM buffers to improve the overall streaming throughput. MEMS-based storage is an exciting new technology that promises to bridge th...

MediaGuard: a model-based framework for building streaming media services

A number of technology and workload trends motivate us to consider the appropriate resource allocation mechanisms and policies for streaming media services in shared cluster environments. We present MediaGuard – a model-based infrastructure for building streaming media services – that can efficiently determine the fraction of server resources required to support a particular client request over...

Retransmission-based error control for scalable streaming media systems

Large-scale continuous media (CM) system implementations require scalable servers most likely built from clusters of storage nodes. Across such nodes, random data placement is an attractive alternative to the traditional round-robin striping. One benefit of random placement is that additional nodes can be added with low data-redistribution overhead such that the system remains load balanced. On...

MediaGuard: a Model-Based Framework for Building QoS-aware Streaming Media Services

benchmarking, enterprise media servers, workload analysis, performance modeling, synthetic workload generator, admission control A number of technology and workload trends motivate us to consider the appropriate resource allocation mechanisms and policies for streaming media services in shared cluster environments. First, workload measurements of existing media services indicate a "peak-to-mean...
