The Impact of Peer-to-Peer Networks on the Management of Internet Service Provider Platforms
by Gerhard Hasslinger, Deutsche Telekom, T-Systems, Technologiezentrum Darmstadt, Germany

Since the year 2000 peer-to-peer (P2P) applications became a main driver of increasing Internet traffic volume and established a new paradigm to launch services in a distributed self-organizing environment. P2P file sharing networks presently contribute 50% - 80% of the traffic on broadband access platforms in Europe and USA. The peer-to-peer principle offers flexible support for multimedia communication in Internet communities with many additional functionalities as compared to client server systems. Therefore computation power, storage and access bandwidth of the peer terminal equipment can be made available to a community enhanced with distributed architecture concepts for data replication etc.
The tutorial starts from an overview of peer-to-peer protocols, their communication and network structures and addresses emerging peer-to-peer applications beyond file sharing. A main focus is on the ambivalent role of P2P networking for Internet service providers, who presently see file sharing as a main user demand in broadband Internet access, although with unresolved issues of digital piracy. In addition, they expect to face competition from services being offered via P2P overlays on IP networks, which may spread over next generation networks including mobile environment in a trend to an all-IP expansion.
Methods for detecting and analyzing P2P traffic in IP platforms are presented together with approaches to cope with overheads and an inefficient assignment between the P2P overlay and the IP network layer. The effect on traffic management and engineering is discussed and, last not least, even if file sharing has no strict demands for quality of service (QoS), the current application and traffic mix has major influence on the appropriate QoS architecture to support an increasing variety of services in IP networks.

The contents is structured in four main parts:
1. Peer-to-Peer Applications, Protocols and Network Topologies
2. Internet Traffic Growth & Profiles: Analysis of a Dominant Peer-to-Peer Load
3. Cross Layer Issues: Broadband IP Infrastructure and P2P Overlay Networks
4. Quality of Service Aspects for P2P & Other Applications in a Multi Service IP Platform
