NeTS-NR: Next-Generation Broadband Access Networks

现代社会越来越依赖互联网来获取即时信息，宽带接入将对这一点产生强烈的积极影响。本项目将创造新的宽带接入网络架构，协议和算法的设计，分析和操作的新知识。 它将专门研究宽带接入网中的统一调度和资源分配，以及建设“开放接入网”的网络经济学。 在接入网络中，控制平面延迟很大，因为最终用户和中心局（用户通过其连接到互联网）相隔很远，通常为几公里。 因此，用于基于分组的网络的已知调度算法难以应用。因此，在这个项目中，新的知识将被创建在分层调度算法，这是“堂兄弟公平”（而不是“兄弟公平”）。需要开发公平的、支持不同服务类别的、保证服务质量（QoS）的、可扩展用户数的远程调度算法。还将创造关于网络经济学的新知识，以建立"开放式接入网络“，旨在促进多个服务提供商之间的竞争。

Modern society is becoming increasingly dependent on the Internet for instant access to information, and the broadband access will have a strong positive im-pact on this. This project will create new knowledge on the design, analysis, and operation of novel broadband access network architectures, protocols, and algo-rithms. It will specifically investigate unified scheduling and resource allocation in broadband access networks, as well as network economics for building ``open access networks''. In access networks, control-plane delays are large since end users and the central office (through which users connect to the Internet) are separated by a significant distance, typically several kilometers. Hence, known scheduling algorithms for packet-based networks are difficult to apply. Therefore, in this project, new knowledge will be created on hierarchical scheduling algorithms which are ``cousin fair" (as opposed to ``sibling fair"). Remote-scheduling algorithms need to be developed which are fair, support dif-ferent classes of service, provide guarantees on Quality of Service (QoS) and are scalable in number of users. New knowledge will also be created on network economics for building ``open access networks'', designed for competition among multiple service providers.
