Peer aggregation using marks with dynamic and multilevel organization

The topology mismatching is one of major factors that cause the low efficiency in P2P system and the consumption of large quantity of network bandwidth, while peer aggregation is a kind of practical way to make topology matching. This paper firstly introduces a multilevel marked system. According to the marked symbol, peers can progressively find theirs neighbor peers in a better way to achieve the goal of aggregation. Then we build a simulation environment to analyze its performance, the experimental results show that this method can implement peer aggregation rapidly and well adapt to the turbulence caused by peer failure.
