Understanding the Dynamic of Peer-to-Peer Systems

چکیده
Though a few previous research efforts have investigated the peer availability of P2P systems, the understanding of peer dynamic is far from adequate. Based on the running log of a file-sharing P2P system, we produced a more thorough measurement of the dynamic natures of P2P system. We further show that due to the methodology limitation, crawler based measurement can not precisely capture system dynamic natures as a whole. In this paper, we also emphasize some simple yet important dynamic metrics, which are omitted or neglected by previous studies because of state of the art in durability analysis at that time. By a fine-grained analysis on the preliminary findings, we reveal a series of useful implications for the design of P2P systems.

Rater Errors among Peer-Assessors: Applying the Many-Facet Rasch Measurement Model
In this study, the researcher used the many-facet Rasch measurement model (MFRM) to detect two pervasive rater errors among peer-assessors rating EFL essays. The researcher also compared the ratings of peer-assessors to those of teacher assessors to gain a clearer understanding of the ratings of peer-assessors. To that end, the researcher used a fully crossed design in which all peer-assessors ...

Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

متن کاملTAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...
