摘　　要：当前网络中间件服务部署方式僵化单一,难以支持未来多样化的网络服务需求.针对此问题,本文从可重构信息通信基础网络中引入元服务的思想,提出一种支持在控制层进行定制编排以及在数据面按需部署的服务路由机制.该机制将服务路径构建问题建模为多约束最优化问题,并针对性设计了分布式选择探测算法,通过对探针的分布式选择处理进行最优服务路径的构建.仿真结果表明,相较于现有算法,本文提出的服务路由机制在付出较小探测开销的情况下,有效提高了路径服务质量以及服务请求成功率.The current way of service deployment using network middleware is too rigid to support the future demand for a variety of network services. Aiming at this problem,this article puts forward a service routing mechanism supporting the customized scheduling in the control layer and the on-demand deployment in the data plane,which is based on the introduction of atomic service from the reconfigurable information communication basal network. According to the operation of this mechanism,this paper models the service routing problem as the multiple target optimization problem under the multi-restrictions,and designs the distributed selection probing algorithm,which constructs the optimal service path through the process of distributed probe selection. Compared with the existing algorithms,the results of simulation showthat the service routing mechanism improves the success rate of the service requests and network resource utilization and reduces the service deployment costs.
