Toward Self-Managed Media Stream Processing Service Overlays

On-demand media stream processing service provisioning on top of a service overlay network (SON) has emerged as a promising approach to providing quality-aware and failure-resilient media streaming services. Although previous work has addressed different problems in media streaming, it is still an open problem to manage SON under dynamic stream environments. In this paper, we propose a novel model-based adaptive SON management framework that can achieve better QoS-aware media stream processing services than unmanaged SONs. We first describe a statistical SON model that can capture the popularity of different service functions and the interaction patterns between different services. We then present the model-based SON management framework and use the SON topology manager as a case study to illustrate the main idea. We are implementing a prototype of the self-managed SON framework and our initial experimental evaluation shows promising results of our approach.
