Analysis of Enterprise Media Server Workloads: Access Patterns, Locality, Dynamics, and Rate of Change

Abstract: The main issue we address in this report is the workload analysis of today's enterprise media servers. This analysis aims to establish a set of properties specific for enterprise media server workloads and to compare them with well known related observations about web server workloads. We propose two new metrics to characterize the dynamics and evolution of the accesses, and the rate of change in the site access pattern, and illustrate them with the analysis of two different enterprise media server workloads collected over a significant period of time. Another goal of our workload analysis study is to develop a media server log analysis tool, called MediaMetrics, that produces a media server traffic access profile and its system resource usage in a way useful to service providers. Notes: A shorter version of this paper is to be published in ACM NOSSDAV 2002, the 12th International Conference on Network and Operating System Support for Digital Audio and Video, 12-14 May 2002, Miami Beach, Florida.
