Web100: Facilitating Effective and Transparent Network Use

该建议旨在创建TCP自动调整，以便TCP应用程序充分利用可用带宽，而无需专家进行离线手动调整。工作的一部分是TCP管理信息库（MIB）的设计，首先确定性能瓶颈在哪里（接收器，发送器或网络路径本身），然后使用该信息在用户进程（autotuning）级别执行自动和动态TCP调优。这项工作的主要应用重点是使用FTP进行科学批量数据传输。优化FTP代码的实现是这项工作的一部分。 在进行开发工作的同时，该项目还将提供大量的用户支助服务和与供应商联络。开发将基于商用英特尔硬件和Linux操作系统，然而，目标是让其他操作系统供应商在其内核中采用并整合TCP自动调优。

This proposal is aimed at creating TCP autotuning so the TCP applications take full advantage of the available bandwidth without the need for off-line manual tuning by the experts. Part of the work is to the design of TCP Management Information Base (MIB) first for identifying where the performance bottleneck is (receiver, transmitter or the network path itself) and then use that information for performing automatic and dynamic TCP tuning at the level of the user process (autotuning). The primary application focus of this effort is on the scientific bulk data transfer using FTP. Implementation of an optimized FTP code is part of this work. In parallel with the development effort the project will also pursue substantial user support services and vendor liaison. The development will be based on the commodity Intel hardware and Linux OS, however, the goal is for other OS vendors to adopt and incorporate TCP autotuning in their kernels.
