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.

端到端的高性能网络必须继续发展，以与计算生态系统保持同步。尽管社区在高性能计算方面继续取得了长足的进步，但传输科学家产生的大量数据的能力未能相应地增加。当科学家花时间处理数据流动，或者由于缺乏及时访问数据而受到限制时，科学进步的潜力就会受到阻碍。如今，有许多应用程序社区在TCP/IP中著名的绩效问题苦苦挣扎，以便完成他们需要做的实际工作。该提案将支持Phoebus的持续发展和部署，Phoebus是一项协议和服务实施，以改善端到端转移到迫切速度。 phoebus提供了一个网络“镶嵌”，该网络使用附加的协议和功能层增强网络拓扑。 Phoebus在最终主机上利用无处不在的TCP/IPv4实现，同时提供适配器以转化为广泛区域的各种替代协议，包括即时创建虚拟网络。许多数据密集型应用程序可以使用phoebus而不进行修改，也无需进行任何系统级别的更改。Phoebus使用称为XSP的会话层协议，用于可扩展的会话协议，用于端到端通信，并在网络不同阶段上使用各种传输层协议实例。在许多情况下，可以通过简单地使用基于网络条件和属性调整的现有协议来提高性能。同样，当可以做出有关基础网络的更多假设时，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WAN加速器。该项目将与各个应用程序社区一起使用，以根据需要修改其软件，以利用Phoebus和XSP。这将使创建自动调整的数据移动服务，以及创建电器以充当动态电路网络的“坡道”。因此，更广泛的影响将包括显着改善科学应用的数据传输性能。智力优点是在作品创造性的方法中发现的，即使WAN加速度的概念适应高延迟延迟环境的高型带宽高。
