StreamSocial: A P2P streaming system with social incentives
A World of Wireless, Mobile and Multimedia Networks, International Symposium on
By Osama Abboud, Thomas Zinner, Eduardo Lidanski, Konstantin Pussep, Ralf Steinmetz
Issue Date:June 2010
P2P Streaming has attracted much attention recently with promises for more revenues and better load distribution. In parallel, social networking has changed how people interact using the web. One interesting use-case for next generation IPTV is Social TV. ...
Adaptive server allocation for peer-assisted Video-on-Demand
Parallel and Distributed Processing Workshops and PhD Forum, 2011 IEEE International Symposium on
By Konstantin Pussep,Osama Abboud,Florian Gerlach,Ralf Steinmetz,Thorsten Strufe
Issue Date:April 2010
Dedicated servers are an undesirable but inevitable resource in peer-assisted streaming systems. Their provision is necessary to guarantee a satisfying quality of experience to consumers, yet they cause significant, and largely avoidable cost for the provi...
Impact of Self-Organization in P2P Overlays on Underlay Utilization
Internet and Web Applications and Services, International Conference on
By Konstantin Pussep, Simon Oechsner, Osama Abboud, Miroslaw Kantor, Burkhard Stiller
Issue Date:May 2009
Peer-to-Peer (P2P) systems gained popularity and are responsible for a large share of today's Internet traffic. Nevertheless, their dynamic nature and the intended lack of control through central instances make their behavior unpredictable and, therefore, ...
Underlay awareness in P2P systems: Techniques and challenges
Parallel and Distributed Processing Symposium, International
By Osama Abboud,Aleksandra Kovacevic,Kalman Graffi,Konstantin Pussep,Ralf Steinmetz
Issue Date:May 2009
Peer-to-peer (P2P) applications have recently attracted a large number of Internet users. Traditional P2P systems however, suffer from inefficiency due to lack of information from the underlay, i.e. the physical network. Although there is a plethora of res...
A Peer-to-Peer Recommender System with Privacy Constraints
Complex, Intelligent and Software Intensive Systems, International Conference
By Konstantin Pussep, Sebastian Kaune, Jonas Flick, Ralf Steinmetz
Issue Date:March 2009
A recommender system can be used to suggest users potentially interesting content based on their previous consumption behavior. Such services already became common in centralized systems, such as Amazon, and approaches exist for decentralized recommender s...
Modelling the Internet Delay Space Based on Geographical Locations
Parallel, Distributed, and Network-Based Processing, Euromicro Conference on
By Sebastian Kaune, Konstantin Pussep, Christof Leng, Aleksandra Kovacevic, Gareth Tyson, Ralf Steinmetz
Issue Date:February 2009
Existing approaches for modelling the Internet delay space predict end-to-end delays between two arbitrary hosts as static values. Further, they do not capture the characteristics caused by geographical constraints. Peer-to-peer (P2P) systems are, however,...
Embracing the Peer Next Door: Proximity in Kademlia
Peer-to-Peer Computing, IEEE International Conference on
By Sebastian Kaune, Tobias Lauinger, Aleksandra Kovacevic, Konstantin Pussep
Issue Date:September 2008
At present, the probability of selecting
On NAT Traversal in Peer-to-Peer Applications
Enabling Technologies, IEEE International Workshops on
By Konstantin Pussep, Matthias Weinert, Aleksandra Kovacevic, Ralf Steinmetz
Issue Date:June 2008
A widely used technique to overcome the shortage of unique public IP addresses is Network Address Translation (NAT), which hides several hosts behind a single public address. This method works smoothly with client-server architectures; however, it causes s...
Overlay Bandwidth Management: Scheduling and Active Queue Management of Overlay Flows
Local Computer Networks, Annual IEEE Conference on
By Kalman Graffi, Konstantin Pussep, Sebastian Kaune, Aleksandra Kovacevic, Nicolas Liebau, Ralf Steinmetz
Issue Date:October 2007
Peer-to-peer and mobile networks gained significant attention of both research community and industry. Applying the peer-to-peer paradigm in mobile networks lead to several problems regarding the bandwidth demand of peer-to-peer networks. Time-critical mes...
Media-aware networking for SVC-based P2P streaming
Found in: Proceedings of the 21st international workshop on Network and operating systems support for digital audio and video (NOSSDAV '11)
By Dominik Stingl, Konstantin Pussep, Osama Abboud, Ralf Steinmetz
Issue Date:June 2011
There are currently two concurrent trends in the Internet. First, the number of Internet users and their connection speeds are increasing rapidly. Second, Internet-based applications are dominating how people receive information, communicate, and entertain...
Advanced prefetching and upload strategies for P2P video-on-demand
Found in: Proceedings of the 2010 ACM workshop on Advanced video streaming techniques for peer-to-peer networks and social networking (AVSTP2P '10)
By Aleksandra Kovacevic, Konstantin Pussep, Markus Mueller, Osama Abboud, Ralf Steinmetz
Issue Date:October 2010
The peer-to-peer (P2P) paradigm has recently shown promise in enhancing performance and decreasing costs of classical client/server Video-on-Demand (VoD) systems. Since current P2P VoD designs began with BitTorrent concepts and its school of thought, littl...
Load balancing for multimedia streaming in heterogeneous peer-to-peer systems
Found in: Proceedings of the 18th International Workshop on Network and Operating Systems Support for Digital Audio and Video (NOSSDAV '08)
By Aleksandra Kovacevic, Kalman Graffi, Konstantin Pussep, Ralf Steinmetz, Sebastian Kaune
Issue Date:May 2008
Multimedia streaming of mostly user generated content is an ongoing trend, not only since the upcoming of Last.fm and YouTube. A distributed decentralized multimedia streaming architecture can spread the (traffic) costs to the user nodes, but requires to p...
