Description

Peer-to-Peer (P2P) streaming has recently emerged as a promising approach to deliver video streams to a large number of users or peers. They not only download video streams but also contribute their upload bandwidth to relay the streams to other peers. Since peers participate with their own resources, P2P streaming is scalable and cost effective. However, ordinary peers are unreliable, they can join and leave the system at any time while others might still depend on their availability and resources. Satisfying strict timing requirements of a video streaming service in this context becomes more challenging. Additionally, the popularity of P2P streaming systems also makes them soon targets of sabotage attacks, such as Denial-of-Service ones. A required characteristic of a viable P2P streaming system is therefore the ability to be both robust to peers' dynamics and resistant against attacks, which we name total resilience in this study. This talk summarizes the progress in our study to improve the resilience of P2P streaming systems. First, we introduce the context and the motivations for the study. We then describe and discuss the background with general approaches in P2P streaming and the related work with specific strategies to design resilient P2P streaming systems. Afterwards, a concrete problem description is introduced and more specific research questions are presented. Finally, the approach and ideas of our solutions and some preliminary results are described and discussed. (Betreuer: Prof. Dr. Thorsten Strufe ; Fachreferent: Prof. Dr. Alexander Schill)
