ITR-M: Technologies for Dynamically Extensible Networks

该项目旨在创建支持动态扩展网络的先进硬件和软件技术。可扩展网络服务平台（NSP）支持硬件和软件插件的动态插入，这些插件作为分布式应用程序的网络驻留助手。为了实现最大的影响，可扩展网络需要复杂的控制机制，使应用程序开发人员能够指定如何配置应用程序会话，同时允许网络灵活地将单个会话映射到可用资源并适应单个用户偏好。该项目将开发和演示可扩展的高性能nsp，并将创建一个软件网络扩展系统（NES），以根据需要自动配置应用程序会话。除了变得更加灵活之外，网络还必须变得更加健壮，以便支持高级关键任务应用程序。假设网络路由器在用户为更大的社会利益而合作的良性环境中运行已不再合理。国家网络基础设施面临越来越多的挑战，因此有必要设计能够可靠运行并提供卓越性能的系统，即使在极端交通条件下也是如此。该项目将开发管理系统资源的实用设计，以确保即使在最苛刻的高性能环境中也能稳健地运行网络。

This project seeks to create advanced hardware and software technologies for supporting dynamically extensible networks. Extensible Network Services Platforms (NSP) support the dynamic insertion of hardware and software plugins that serve as network-resident assists to distributed applications. To enable the greatest impact, extensible networks require sophisticated control mechanisms to enable application developers to specify how application sessions may be configured, while allowing the network the flexibility to map individual sessions onto available resources and to accommodate individual user preferences. This project will develop and demonstrate scalable, high performance NSPs and will create a software Network Extension System (NES) to automatically configure application sessions on demand. In addition to becoming more flexible, networks must become more robust, in order to support advanced mission-critical applications. It is no longer reasonable to assume that network routers operate in a benign environment where users cooperate for the larger social good. The growing challenges to the nation's cyber-infrastructure make it necessary to design systems that can operate reliably and deliver excellent performance, even in the presence of extreme traffic conditions. This project will develop practical designs for managing system resources to ensure robust network operation, even in the most demanding, high performance environments.
