Service Field Placement Problem Based on P2P Network Framework

A two-tier service placement strategy based on the P2P overlay network framework is proposed. Fields are first placed on the top layer overlay nodes, and then the service components of various functions are placed within the field according to some strategy. The optimization models are built for the single field placement problem and fellowship fields placement problem respectively. And several algorithms are introduced to solve these problems. The simulation result shows the fellowship fields placement strategy decrease the cost of inter-field composed service.
