Two-tier Service Placement Strategy in Layered P2P Network
Huaihu Cao · Jisuanji gongcheng · 2010
A two-tier service placement strategy based on the P2P overlay network framework is proposed. The optimization model is built for intra-domain Service Placement Problem(SPP) and an efficient algorithm is designed to solve the problem. Several cost calculation methods are adopted to fit different structures of the composed service. Simulation result shows the intra-domain service placement strategy decreases the cost for intra-domain composed services,and the two-tier service placement strategy decreases the total cost of composed services.
