BitTorrent Session Characteristics and Models
نویسندگان
چکیده
The paper reports on a modeling and evaluation study of session characteristics of BitTorrent traffic. BitTorrent is a second generation Peer-to-Peer (P2P) application recently developed as an alternative to the classical client-server model to reduce the load burden on content servers and networks. Results are reported on measuring, modeling and analysis of application layer traces collected at the Blekinge Institute of Technology (BIT) and a local ISP. For doing this, a dedicated measurement infrastructure has been developed at BIT to collect P2P traffic. A dedicated modeling methodology has been put forth as well. New results are reported on session characteristics of BitTorrent, and it is observed that session interarrivals can be accurately modeled by the hyper-exponential distribution while session durations and sizes can be reasonably well modeled by the lognormal distribution.

The paper reports on a detailed study of the BitTorrent content distribution system. We first present a measurement infrastructure designed to allow detailed, message-level capture and analysis of P2P traffic. An associated modeling methodology is presented as well. These tools have been used to measure and model the BitTorrent protocol, which is observed to exhibit exponential characteristics ...
متن کاملUnveiling the BitTorrent Performance in Mobile WiMAX Networks
As mobile Internet environments are becoming widespread, how to revamp peer-to-peer (P2P) operations for mobile hosts is gaining more attention. In this paper, we carry out empirical measurement of BitTorrent users in a commercial WiMAX network. We investigate how handovers in WiMAX networks impact the BitTorrent performance, how BitTorrent peers perform from the aspects of connectivity, stabil...
متن کاملLarge Scale Analysis of BitTorrent Proxy for Green Internet File Sharing
Addressing energy efficiency in P2P services has the potential to make the Internet greener since they comprise a major source of the Internet data traffic. In this paper, we consider approaches for green Internet file sharing. We develop simulation models of proxy-based energy efficient BitTorrent as well as legacy BitTorrent on PeerSim P2P simulator, and explore their characteristics on large...
