EAGER: Towards increasing the usage of new high-speed network services by the scientific community

【摘要】提案1038058针对科学界增加新的高速网络服务的使用，该提案是高风险的，高回报的，因为它解决了一个基本的网络问题，即使用“过度配置”IP作为解决拥塞问题的主要方法。虽然这种方法已经（并将继续）取得了相当大的成功，但它只是解决方案的一部分；但是，由于使用这种方法的基础是嵌入式的，因此强烈不鼓励对IP堆栈或协议进行更改。对于以长数据流和数据流为特征的数据应用程序，这种方法尤其成问题。该建议以全新的眼光看待超越普遍存在的IP数据报服务，并考虑电路/虚拟电路网络的替代方案。这项工作将使用Unidata LDM应用程序来演示和实施拟议网络的修改版本，以显示性能的改进和成本的降低。该提案将对LDM及其相关的互联网数据分发项目进行深入研究，以测试将长时间数据流从一般IP网络卸载到虚拟电路选项的可行性。

AbstractProposal 1038058 Towards increasing the usage of new high-speed networkservices by the scientific communityPI: Malathi VeeraraghavanThe proposal is high-risk, high payoff because it is addressing a fundamental networking problem which has used "overprovisioning" IP as the primary way to address congestion issues. While this approach has been (and continues to be) used with considerable success, it is only part of the solution; however, because of the embedded base of use this approach, changes to the IP stack or protocol are strongly discouraged. This approach is particularly problematic for data applications that are characterized by long data flows and streams. This proposal takes a fresh look at going beyond ubiquitous IP datagram services and considers circuit/virtual circuit networking alternatives. The effort will use the Unidata LDM application to demonstrate and implement a modified version of proposed network to show improvements in performance as well as reduction in costs. The proposal will undertake an in-depth study of LDM and its associated Internet Data Distribution project to test the feasibility of off-loading long duration data flows from the general IP network to virtual-circuit options.
