NeTS: Small: Collaborative Research: Boosting Inter-Domain Scheduled Dynamic Circuit Services (SDCS)

在云计算的新兴领域和其他领域中的各种应用需要稳定、低延迟的网络连接以及协同调度网络和服务器资源的能力。因此，一些网络提供商最近开始部署调度动态电路服务（SDCS）。在这种服务下，网络提供商允许其客户对持续固定持续时间的固定速率电路提出调度请求，以便尽早使用或在未来的期望时间点预定使用。虽然具有显著的潜在影响，但SDCS目前几乎不支持跨不同管理域的电路的动态路由和调度。缺乏对域间路由的充分支持是SDCS全面部署的主要障碍。本项目的主要目标是通过设计分布式解决方案来解决这一挑战，支持跨域的预定动态电路服务。该项目包括两个相互关联的推力：（i）理论，重点是设计分布式路由算法的SDCS，可证明收敛，并提供性能保证的用户性能指标的问题; 以及（ii）协议设计和实现，侧重于SDCS的新域间路由协议（称为调度电路路由协议（SCRP））的设计、开发和真实的网络原型。该项目的成功完成有望影响属于医疗，科学和商业领域的各种高通量和实时应用，并促进通信网络的新生态系统的创建。该项目通过与国际学术和工业合作伙伴以及网络运营商的合作，进一步努力实现高影响力。各级学生将参与真实的网络实验，并开发SDCS支持的创新应用程序，例如基于触觉的通信。

A variety of applications in the nascent field of cloud computing and in other fields requires stable, low-delay network connectivity together with capabilities of co-scheduling network and server resources. As a result, several network providers have recently started to deploy scheduled dynamic circuit services (SDCS). Under such services, a network provider allows its customers to place scheduling requests for a fixed-rate circuit lasting for a fixed duration, for either earliest possible usage or scheduled usage at a desired point of time in the future.While carrying significant potential impact, SDCS currently provide little support for dynamic routing and scheduling of circuits across different administrative domains. This lack of adequate support for inter-domain routing represents a major hurdle to the full-scale deployment of SDCS. The main objective of this project is to tackle this challenge by devising distributed solutions supporting scheduled dynamic circuit services across domains. The project consists of two inter-related thrusts: (i) theory, which focuses on the problem of devising distributed routing algorithms for SDCS that provably converge and provide performance guarantees on user-performance metrics; and (ii) protocol design and implementation, which focuses on the design, development, and real network prototyping of a new inter-domain routing protocol for SDCS, referred to as the scheduled circuit routing protocol (SCRP).Broader Impact: Successful completion of this project promises to impact a wide array of high-throughput and real-time applications belonging to medical, scientific and commercial domains, and facilitate the creation of a new ecosystem for communication networks. The project is further striving for high impact through collaborations with international academic and industrial partners, and network operators. Students at all levels will be engaged in real network experiments and in the development of innovative applications enabled by SDCS, such as haptic-based communication.
