EAGER: GENI Experiments on Mobile Gigabit Wireless Access with Core-to-Edge Network Coding

该项目旨在利用Geni深度可编程的核心和无线边缘网络来实施和评估最近提出的为移动设备提供可预测的端到端性能的方法。这些方法涉及流间和流内网络编码、多路径路由、可用带宽估计和空闲带宽利用等技术。虽然这些技术是通过模拟来研究的，但如果没有GENI的细粒度测量和控制能力，就永远不可能在运营网络上验证它们的模型和限制。如果不克服未来互联网的带宽瓶颈和移动开销，就不可能实现真正的泛在宽带网络，无论是在核心还是在无线边缘。在许多情况下，早期的无线接入部署对移动用户的端到端数据速率只有轻微的改善。这项研究的结果可能会影响美国正在进行的宽带倡议。

This project aims to leverage GENI's deeply programmable core and wireless edge networks to implement and evaluate recently proposed approaches for delivering predictable end-to-end performance to mobile devices. These approaches involve techniques such as inter-flow and intra-flow network coding, multipath routing, available bandwidth estimation, and spare bandwidth exploitation. While these techniques have been studied using simulations, it has never been possible to validate their models and their limits on an operational network without GENI's fine-grained measurement and control capabilities. True ubiquitous broadband networking cannot be realized without overcoming the bandwidth bottleneck and mobility overheads of future Internet, both at the core and at the wireless edge. Early wireless access deployments in many instances resulted in only marginal improvements in end-to-end data rates to mobile users. Outcomes from this research may influence the ongoing broadband initiatives in the United States.
