NeTS: Small: New Abstractions for First-hop Networking in Cloud Data Centers

该项目旨在提高未来数据中心计算服务器和网络的性能，使越来越多的性能敏感型应用程序能够在每台服务器上共存。为了让服务器上的多个应用程序以高速驱动网络接口卡（NIC），本研究的目的是重新考虑在服务器网络堆栈的各个层中采用的机制，并创建新的接口和抽象层之间和应用程序。这项研究将提高云计算基础设施的可扩展性、利用率和效率，使提供商能够支持更多的应用程序和租户，同时保持其当前的基础设施足迹。该项目旨在为服务器操作系统和网络接口卡（NetworkInterfaceCards，简称NIC）开发新的算法和编程抽象，以改善出站网络流量的调度。这些算法将克服当前的性能瓶颈，并将提高多个应用程序以高速驱动NIC的能力，其雄心勃勃的目标是维持线路速率，同时满足应用程序延迟/吞吐量/公平性目标以及基础设施范围的利用率和效率目标。PI计划将拟议的研究纳入威斯康星大学麦迪逊分校的课程。PI将组织各种针对网络工程师、本科生和来自代表性不足群体的高中生的“网络编程训练营”。

This project seeks to improve the performance of future data center compute servers and networks, enabling a growing number of performance-sensitive applications to co-exist on each server. To allow multiple applications on a server to drive the Network Interface Card (NIC) at high speed, this research aims to rethink the mechanisms employed in various layers of the server networking stack, and create new interfaces and abstractions between the layers and for applications. This research will lead to improved scalability, utilization, and efficiency of cloud computing infrastructure, allowing providers to support many more applications and tenants while maintaining their current infrastructure footprint. This project seeks to develop new algorithms and programming abstractions for server operating systems and Network Interface Cards (NICs) to improve scheduling of outbound network traffic. These algorithms will overcome current performance bottlenecks, and will improve the ability for multiple applications to drive a NIC at high speed, with the ambitious goal of sustaining line rates while meeting application latency/throughput/fairness objectives as well as infrastructure-wide utilization and efficiency objectives. The PIs plan to integrate the proposed research into courses at UW-Madison. The PIs will organize various `network programming bootcamps' aimed at network engineers, undergraduate students, and high school students from under-represented groups.
