中文摘要： 在以“光驱动”、“云使能”和“软定义”为特征的无线接入网发展趋势下，多种资源形式的共存加剧了资源管理与调配的实现难度，突显出多维异构网络环境下资源利用低效的问题，迫切需要资源调度模式由单一化向协同化方向发展。本项目针对光与无线融合接入网资源的多样性和异构性问题，探索资源协同优化理论与实现机理，首次提出以“垂直融合”与“水平融合”两种融合方式来体现资源协同的创新思想，并借助软件定义网络技术实现两种融合方式下多维异构资源的统一控制。重点攻克网络资源复杂性与高效适配、服务资源异构性与统筹规划、资源信息封闭性与统一控制的关键问题。在资源协同优化理论模型、控制平面实现机理与网络应用上取得创新与突破，为光与无线融合接入网的发展与应用提供重要的理论依据和技术支撑。

英文摘要： With the development of wireless access networks which are characterized by “optical-driven”, “cloud-enabled” and “software-defined”, multi-resource co-existing exacerbates the difficulty of implementation of resource management and allocation. The inefficiency of network resource utilization is becoming a crucial problem in a multi-dimension and heterogeneous network environment, which forces the transition of resource allocation from “single resource allocation” to “multiple resources collaborative allocation”. This project focuses on the diversity and heterogeneity in an optical and wireless converged access network, and researches on the resources collaborative optimization theories and implementation mechanisms. We propose two kinds of resource convergence modes to realize resources collaboration, namely “vertical convergence” and “horizontal convergence”. By exploiting Software-Defined Networking (SDN) technology, the two resource convergences can be implemented in a unified control manner. In this project, we mainly deal with three key problems which are the complexity of network resource versus high adaptation, the heterogeneity of service resource versus comprehensive planning and the closed resource information versus unified control. The goal of this project is to make a breakthrough and innovation on resources collaborative optimization theories, control plane implementation mechanisms and networking applications. It also aims to provide a theory foundation and technical support for optical and wireless converged access networks.
