中文摘要： 在大规模光组网过程中，多种网络资源与交换技术相互交织和叠加，加剧了全网业务控制与资源管理的实现难度，凸显了"大规模组网控制复杂与网络资源利用低效"的问题，迫使光网络由"刚性控制"向"柔性控制"，由"闭合控制"向"开放控制"发展。本项目立足光纤通信组网与控制领域前沿和国家战略发展需要，针对上述大规模异构组网应用过程中的关键科学问题，提出了一种软定制光网络新型体系结构（Software Customized Optical Networks, SCON）,重点研究面向灵活控制的软定制理论与实现机理，攻克可软件定制的业务处理、控制机制、传输设备等研究难点。本着网络控制体系柔性化、开放化的观点，借助网络元素灵活可编程控制思想，将网络元素调谐过程与面向业务的动态组网有机结合，采用系统分析、组网建模、协议仿真等多种手段，实现业务动态需求与开放式控制接口的最佳适配，为软定制光网络的发展奠定理论基础。

英文摘要： In the process of large-scale optical networking, the crossovers and overlaps of various network resources and different kinds of switch technologies have been making the implementation of unified service control and resources management difficult. And the complexity of the control of large-scale networking as well as the network resources utilization's inefficiencies is forming a crucial challenge which we have to be faced with. All of those described above force the transition of current optical networks from "rigid control" to "flexible control" and from "closed control" to "open control". The project here, focuses on the forefront of optical communication networking and control technologies with regards to the national strategic development requirements,put forward an innovative solution which is so-called Software Customized Optical Networks (SCON for short) to against those key science problems mentioned. Software customized theories for flexible control are mainly researched and three diffcult key points will be overcome, which are service processing,control mechanism,and transport equipment.In order to soften and publish the network control architecture and further the state of current network elements to be flexible and controlled via programming, we will concentrate on comprehensive combination of the
