8 Private Questions (in german)


From 2008 to 2011 I was working on EU ICT project SmoothIT that aims in shaping the overlay traffic (such as P2P networks, or Content Delivery Networks) to reduce the inter-domain costs of Internet Service Providers (ISPs).

There I was involved into research, development, and management activities around the ISP-friendliness of P2P applications. My responsibilities included besides the scientific activities: software development, coordination of working groups (including the workpackage "Development and Implementation"), presentations at project reviews.

Research Areas:

Peer-to-Peer Systems

I mostly address the scenario of hybrid systems for video-on-demand streaming. Here peers re-distribute content to offload content servers. Special care must be taken to address the requirements of various players:

  1. Content providers who try to save bandwidth costs (and reduce the peak load on servers),
  2. Users who want to have stable and reliable streaming experience at low costs,
  3. Network providers who want to limit the P2P-induced traffic on costly inter-domain links

Some of the mechanism applied in this context are:

  • P2P-based caching
  • Adaptive server and cache allocation for constant quality with minimized distribution costs (Paper link)
  • P2P networks based on  set-top boxes (modems, digital receivers) for more reliable and manageable peer contribution (ongoing work)
  • Locality- and Underlay-awareness in P2P Systems (Paper link)
  • Decentralized recommender systems with privacy constraints (Paper link)

Current Work:

I'm currently writing a paper about energy-awareness of Peer-assisted systems based on set-top boxes

Research Topics

  • Energy-awareness of STB-based P2P Networks
  • Adaptive Resource Allocation for P2P Streaming
  • Incentive-based Traffic Management of (P2P) Overlay Traffic
