中文摘要： 近年来，可编程网络因其在负载均衡、内容分发以及网络安全性等方面的巨大优势而受到了广泛关注。然而，作为其核心研究方向之一，可编程网络环境下的服务，尤其是多粒度服务与服务组合的问题因其学科交叉性强、建模分析难度高等特点而未得到深入地研究。鉴于上述分析，本课题将针对以下问题进行深入研究：1）在可编程网络特点的基础上参考SONs架构提出可编程网络模型；2）提出服务粒度划分方法以及相应的模型，并在此基础上设计多粒度服务在可编程网络中的优化部署方法；3）设计跨层次的可编程网络环境下不同粒度服务之间的服务组合算法，以提高服务组合效率，减少冗余链路以及冗余信息的产生；4）针对底层网络开发基于可编程网络路径选择与路由算法，以及路由重建与修复策略。本课题的研究将会为可编程网络环境下多粒度服务系统的设计提供良好的理论和实践支撑，为解决云计算技术中的关键问题提供良好的基础，具有深远的科学意义与广阔的应用前景。

英文摘要： In the latest decade, rapidly growing attentions have been put on programmable network, due to its advantages in load balancing, content distribution and security. However, the research on service, especially multi-granularity service and service composition under programmable network structure is far from mature, even though they are critical to the development and application of programmable network. This may attribute to their extreme complexity in both modeling and analysis. Based on the aforementioned observation, this project will explore several related areas in programmable network. 1) a programmable network model will be provided based on SONs framework. 2) the question of how to classify the granularities of services will be answered with a proper multi-granularity service model. Then, multi-granularity service distribution methods will be proposed based on the programmable network model. 3) a novel service composition algorithm will be designed for multi-granularity services to enhance the efficiency of the network, reduce redundant links as well as redundant information. 4) In network layer, a programmable network based routing algorithm will be developed, and problem of routing restoration will be considered. The aim of this project is to provide a powerful set of tools for analyzing and designing m
