ABSTRACT This paper presents the measurement study of locality-aware Peer-to-Peer solutions on Internet Autonomous System (AS) topology by reducing AS hop count and increase nearby source nodes in P2P applications. We evaluate the performance of topology-aware BT system called TopBT with BitTorrent (BT) by constructing AS graph and measure the hops between nodes to observe the impact of quality of service in P2P applications.   KEYWORDS Peer-to-Peer , BitTorrent , TopBT , Locality , Autonomous System Cite this paper Talha, M. , Aldhaheri, R. and Awedh, M.

ABSTRACT A solution of nonlocal EPR correlation between counter-propagating pair of polarization entangled photons emitted from a common source at S and detected at points P and Q is sought outside the EPR’s reality criterion of local causality but within the framework of time-symmetric quantum electrodynamics allowing the bi-directional signal transmission P  S Q on the double-light cone where the future and the past cones share common light paths connecting the photon source S and the detection points P and Q. ...
