Lecture 2: Peer to Peer Systems

چکیده
There are currently one billion mobile devices (e.g. phone, PDAs etc) worldwide, a figure which is rising rapidly. On the other side of the scale, predictions indicate there will be 490 million Internet users by the year-end 2002 and over 765 million by year-end 2005. Each user in this massive network has the CPU capability of more than 100 times that of an early 1990s supercomputer and surprisingly, GartnerGroup research reveals that over 95% of today's PC power is wasted. The potential of such a distributed computing resource has been in some ways demonstrated recently by the SETI@home project [1], having used over a million years of CPU time at the time of writing.

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...
