End-to-end high performance networking must continue to develop to keep pace with the computing ecosystem. While the community continues to make significant strides in high-performance computing, the ability to transfer the vast amounts of data generated by scientists has failed to increase commensurately. When scientists spend time dealing with data movement, or are limited by lack of timely access to data, the potential for scientific progress is hampered. Today, there are many application communities struggling with the well-known performance problems in TCP/IP in order to do the real work they need to do.This proposal would support the continued development and deployment of Phoebus, a protocol and service implementation for improving end-to-end transfers to gigabit speeds. Phoebus provides a network "inlay" that augments the network topology with an additional layer of protocol and functionality. Phoebus leverages the ubiquitous TCP/IPv4 implementation on the end hosts, while providing an adaptor to translate to a variety of alternate protocols over the wide area, including creation of virtual networks on the fly. Many data-intensive applications can use Phoebus without modification and without making any system-level changes.Phoebus makes use of a session-layer protocol called XSP, for eXtensible Session Protocol, for end-to-end communication and uses various transport layer protocol instances on different segments of the network, as appropriate. In many cases, performance can be improved by simply using existing protocols tuned based on network conditions and properties. Similarly, a high performance TCP alternative can be used when more assumptions about the underlying network can be made.Phoebus is essentially a WAN accelerator for research and education networks. This project will work with various application communities to modify their software as necessary to make use of Phoebus and XSP. This will enable the creation of an automatically tuned data movement service, as well as the creation of appliances to act as "on-ramps" to dynamic circuit networks. Broader impact will therefore include significantly improved data transfer performance for scientific applications. Intellectual merit is found in the work's creative approach to adapting the concept of WAN acceleration to a multi-prototcol high bandwidth high delay environment.

端到端高性能网络必须继续发展，以跟上计算生态系统的步伐。虽然社区在高性能计算方面继续取得重大进展，但传输科学家产生的海量数据的能力并没有相应增加。当科学家花费时间处理数据移动，或者由于无法及时获取数据而受到限制时，科学进步的潜力就会受到阻碍。今天，有许多应用程序社区正在努力解决TCP/IP中众所周知的性能问题，以便完成他们需要做的真正工作。这项提议将支持Phoebus的继续开发和部署，Phoebus是一种用于将端到端传输提高到千兆位速度的协议和服务实现。Phoebus提供了一个网络“嵌入体”，它为网络拓扑增加了一层额外的协议和功能。Phoebus利用终端主机上无处不在的TCP/IPv4实现，同时提供适配器以在广域范围内转换为各种替代协议，包括动态创建虚拟网络。许多数据密集型应用程序无需修改即可使用Phoebus，无需进行任何系统级更改。Phoebus使用称为XSP的会话层协议进行端到端通信，并根据需要在网络的不同网段上使用各种传输层协议实例。在许多情况下，只需使用根据网络条件和属性调整的现有协议即可提高性能。同样，当可以对底层网络做出更多假设时，可以使用高性能的TCP替代方案。Phoebus本质上是研究和教育网络的广域网加速器。该项目将与不同的应用程序社区合作，根据需要修改他们的软件，以利用Phoebus和XSP。这将允许创建自动调谐的数据移动服务，以及创建充当动态电路网络的“入口”的设备。因此，更广泛的影响将包括显著提高科学应用程序的数据传输性能。将广域网加速的概念应用到多协议、高带宽、高延迟环境的创造性方法中，体现了这项工作的智慧价值。
