A cost effective migration path to a fully packet based hybrid fixed/mobile backhaul infrastructure

本研究的目的是开发和演示无源光网络（PON）宽带接入技术与“第四代”（4G）移动无线宽带接入技术集成所需的关键要素。该方法是设计和分析基于以太网的多业务网络架构，该架构跨越并集成了基于光纤的PON和4G无线接入技术。在智能方面，所提出的架构寻求在有线和无线接入网的统一控制和管理方面集成PON和4G无线接入技术。这给集成问题增加了许多具有挑战性的维度。与主流的集中式PON和无线接入网（RAN）架构相比，本文提出的融合接入网方案不仅需要支持完全分布式的PON-RAN集成架构，还需要支持统一的控制平面，对固定光网络和移动无线网络资源进行管理和控制。这就需要以分布式方式运行的新型综合有线和无线无线电控制算法和程序。就更广泛的影响而言，拟议的集成网络方法有可能提供比现有技术和特性更具成本效益的解决方案，从而实现优雅的过渡、快速接受和近期部署。广泛可用的高数据速率网络接入在弥合“数字鸿沟”方面具有重要的社会效益。该项目的综合教育和研究计划的目标是加强纽约城市学院和纽约大都会地区各种代表性不足的社区的招聘和推广。

The objective of this research is to develop and demonstrate critical elements necessary for the integration of passive optical network (PON) broadband access technologies with "Fourth Generation" (4G) mobile wireless broadband access technologies. The approach is to devise and analyze an Ethernet-based multiservice network architecture that spans and integrates fiber-based PON and 4G wireless access technologies.With respect to intellectual merit, the proposed architecture seeks to integrate both PON and 4G wireless access technologies in terms of unified control and management of both wired and wireless access networks. This adds a number of challenging dimensions to the integration problem. In contrast to mainstream centralized PON and radio access network (RAN) architectures, the proposed converged access networking scheme must support not only a fully distributed integrated PON-RAN architecture, but also a unified control plane that manages and controls both fixed optical and mobile radio network resources. This calls for new integrated wireline and wireless radio control algorithms and procedures that operate in a distributed manner.With respect to broader impact, the proposed integrated networking approach has the potential to provide a significantly more cost effective solution than existing technologies and features that could lead to graceful transition, rapid acceptance, and near-term deployment. Widely available, high data rate access to networks has important societal benefits in bridging the "digital divide." The project's integrated education and research program has the goal of enhancing recruitment and outreach to various underrepresented communities at the City College of New York and in the New York metropolitan area.
