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

在新兴的云计算领域和其他领域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预定动态电路服务（SDCS）。在这种服务下，网络提供商允许其客户对持续固定时间的固定速率电路提出调度请求，以便尽早使用或在将来期望的时间点计划使用。虽然具有重大的潜在影响，但SDCS目前对跨不同管理域的电路的动态路由和调度提供的支持很少。缺乏对域间路由的充分支持是全面部署SDCS的主要障碍。该项目的主要目标是通过设计支持跨域调度动态电路服务的分布式解决方案来解决这一挑战。该项目包括两个相互关联的重点：(i)理论，其重点是为SDCS设计分布式路由算法的问题，这些算法可以证明是收敛的，并为用户性能指标提供性能保证；（ii）协议设计和实现，重点是SDCS的新域间路由协议的设计，开发和实际网络原型，称为计划电路路由协议（SCRP）。更广泛的影响：该项目的成功完成有望影响医疗、科学和商业领域的一系列高通量和实时应用，并促进建立新的通信网络生态系统。通过与国际学术和工业伙伴以及网络运营商的合作，该项目将进一步努力提高影响力。各个层次的学生都将参与到真实的网络实验中，并参与到由SDCS实现的创新应用的开发中，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.
