基于chord算法的p2p文件系统。A p2p file system based on chord.

# ... generate 10,000 events; one event every 714 ms on average
# - a join event is generated with prob 10/(10+10+20+100) = 1/14
# - a leave event is generated with prob 1/14
# - a document insertion is generated with prob 1/7
# - a document query is generated with prob 5/7
