> 中文摘要: 今天,宽带社区接入基础设施仍然是下一代网络的主要研究领域之一.除了流行的非对称数字用户环路、光纤同轴混合网和ATM无源光网络,学术界和工业界正日益表现出对于以太网技术应用于宽带社区接入网的巨大关注.试图调查通常的宽带社区接入技术的本质区别,给出全面的理解.综述了通常的宽带社区接入技术,基于复用方法和传输技术发布了新出现的基于以太网技术的社区接入网和非对称数字用户环路、光纤同轴混合网和ATM无源光网络的比较研究.这个比较研究深入地讨论了宽带社区接入技术网络结构、服务模型、通信量模型和服务质量提供.比较研究将有益于将来的宽带社区接入基础设施的研究与实现.
Abstract:Nowadays, the broadband residential access infrastructure remains one of the major research areas for NGN (next generation network). Apart from popular ADSL (asymmetrical digital subscriber loop), HFC (hybrid fiber-coax) and APON (ATM passive optical network), academic communities and industry are increasingly showing great concern about Ethernet technique in the subscriber access network. This paper investigates the substantial differences among the generic broadband residential access techniques and allows a comprehensive understanding of them. The authors survey the generic broadband residential access techniques and present a comparative study on the emerging residential Ethernet-based access solutions with the ADSL, HFC, and APON techniques based on multiplex methods and transport technologies in terms of network architecture, service and traffic models, and QoS (quality of service) provisioning. The comparative study is of benefit to research and implementation of the future broadband residential access infrastructure.
