中文摘要： 应用数学方法开展网络服务管理基础理论研究是本课题的基本立足点。针对网络服务领域的新发展，特别是云计算、物联网和下一代互联网这一大的背景，对网络服务行为基础理论开展研究确有必要。根据课题总体研究思路和技术路线，本课题主要从以下几个方面开展了相应的工作：（1）通过服务矩阵、概率服务矩阵、等价服务、服务不确定性、不确定熵等的数学定义和描述，定性、定量刻画网络服务及其行为，深入研究了服务系统及其行为的不确定性；（2）以P2P服务系统为切入点开展了节点交互行为研究，使用JXTA建立了服务系统验证平台；（3）以π28436;算为基础初步研究了网络服务行为的建模方法及其不确性分析，包括基本的能力模型、规约要求、交互操作、情境依赖建模等；（4）针对云服务，开展了云服务系统的资源调度问题，以openQRM为基础建立了基本的云服务管理平台；（5）以真实的下一代互联网CERNET2为实验环境验证上述理论研究。通过对P2P服务、云服务的真实平台建立、实际问题理论分析与解决，开展了云环境下的服务资源、虚拟设施、网络接入、云服务行为的管理和行为分析及网络服务建模基础理论研究，提高了服务可信性和可管理性，因而具有重要意义。

英文摘要： A study on the fundamental theory on network service management with mathematical methods, this is the focus topic of the project. Based on the development of this domain, such as cloud computing, Internet of things, and NGN, it is necessary to carry out the network service behavior modeling fundamental theory study. According to the overall research schedule, the following aspects of work have been carried out: (1) The definitions of the service matrix, the probability of service matrix, equivalent services, services of uncertainty, and the mathematical definition of uncertainty entropy, are proposed; Qualitative and quantitative depicting of characterization of the network service behavior are studied too; (2) The interactions behaviors of the P2P nodes have been studied with a P2P service system using JXTA protocol; (3) The network service behavior description with πalculus was studied. A preliminary network service behavior modeling and uncertainty analysis method have been proposed. The methods can model the statute requires, interaction, context dependent modeling et al; (4) About the cloud computing services, cloud services resource scheduling method has been studied with openQRM, an open source cloud management platform; (5) The theories proposed have been verified with CERNET2 environment. With P2P services, cloud computing service platform building, the key topics related to theoretical analysis of cloud services environment, resources, virtual facilities, cloud services behavior modeling, of the basic theory of network service, all these have been studied. With these methods, the credibility and manageability of network service can be improved dramatically, which are two critical aspects in network service management.
