Researching on Embedded Chord Routing System
Zhao Da-chuan · 2008
In P2P networks,DHTs reorganize peers into an overlay in the application level,distribute file indexes into the network,and route queries through the overlay.DHTs are robust in the face of failures, attacks and unexpectedly high loads.However,DHTs are still faced with many problems,one of which is the fact that most DHTs do not take into account physical network topology in their original design,thus resulting in high routing latency and low efficiency.Therefore,to improve routing performance is an im- portant direction for research on DHT-based P2P.several research groups independently proposed DHT (distributed hash table)systems,which include Chord,CAN,Pastry and Tapestry.This paper Devise a novel scheme to construct embedded DHT,which can not only improve the routing efficiency,but also inherit the load-balancing feature of the original DHT.To illustrate the feasibility and effectiveness of the scheme,we construct eChord upon the original Chord system.Analysis and simulation demonstrate that our scheme is very effective.
