摘要: 针对服务部署策略不完善的问题,提出P2P覆盖网络框架下自上而下的2级服务部署策略。在顶层P2P网络中部署领域,并在每个领域中部署各种服务组件。对单个领域和伙伴关系领域的放置情况进行建模,使用3种算法进行求解。仿真实验结果表明,伙伴关系领域的邻近放置策略降低了跨领域组合服务的路由开销。

Abstract: This paper proposes a two-level service placement strategy based on P2P overlay network framework. Domains are placed on the top level, and the service components of various functions are placed in each domain. The model is built aiming at the single domain placement and associate domains placement problem, and uses three kinds of algorithm to solve. Simulation result shows the associate domains placement strategy decrease the cost of multi-domain composed service.

Key words: placement strategy, domain, overlay network
