This thesis examines the performance for multimedia distribution and information sharing of social-networking web sites, with a focus on user networks in Facebook. We used real user network data from Facebook together with a synthetic Facebook network in the performance-testing experiments. We tested performance for multimedia distribution and information sharing using three different types of overlay networks: Facebook; structured peer-to-peer (ring topology); and unstructured peer-to-peer (mesh topology). The experiments used Network Simulator 2 (Ns-2) to simulate the network topologies. The results show that structured Peer-to-Peer has the best performance in terms of information transfer, and Facebook has the best performance in regards to average throughput. This thesis shows the strengths and weaknesses of online social networking while sharing information and multimedia content.

Multimedia Distribution

The term peer-to-peer (P2P) was originally used to refer to network protocols where all the nodes had the same role and there were no nodes with specific responsibilities to act as the administrators or supervisors of a network (Ye, Makedon, & Ford, 2004). However, with the evolution of Internet as the dominant architecture for applications, contents, and services, applications and services have gradually migrated from the client-server paradigm to the edge services paradigm and now to the P2P computing paradigm. Therefore, nowadays, the term P2P refers to a class of systems and applications that use distributed resources to perform some function in a decentralized manner, where every participating node can act as both a client and a server (Ye et al., 2004). This article provides an overview of P2P computing, being focused on the types of multimedia distribution services and cooperation models in P2P systems. These models are classified regarding the functionality, the degree of decentralization, and the degree of structure of the information system.

Peer To Peer

Zusammenfassung. In der Gesundheitsversorgung von Menschen, die mit chronischen Krankheiten leben, wird soziale Unterstützung durch «peers» immer bedeutsamer, d. h. durch Personen, die aufgrund ähnlicher Krankheits- und Alltagserfahrungen in einer vergleichbaren Lebenssituation sind. Welche Potenziale, Chancen sowie Grenzen hat «peer-to-peer healthcare» im Kontext von Selbstmanagementförderung? Der Beitrag diskutiert dies anhand von Erfahrungen mit dem Stanford Kursprogramm «Gesund und aktiv leben».
