As data communication has become increasingly important to our society, demands on the networking infrastructure have reached a point where it is desirable to implement an optical packet switching core. The prohibitive cost of large optical buffers has lead to many optical network designs with small buffers on routers. A major challenge in this context is to envision efficient operation scenarios that justify these small buffer networks. This project aims at developing an architecture that implements packet spacing on network links such that suitable statistical properties of network traffic can be ensured and small-buffer networks can be operated efficiently. The specific goals of this project are: (1) understanding of packet spacing and its network-wide impact, (2) development of a pacing node prototype, and (3) consideration of network-wide deployment. The packet spacing architecture developed in this project can help in promoting the broad deployment of optical packet switching technology.Intellectual Merit: The intellectual merit of this project includes three aspects. First, the research will further our understanding of the impact of packet spacing on the whole network (rather than being limited to a single buffer analysis). Second, the pacing architecture will help improve the efficiency of operation of optical core networks and thus improve the Internet as a whole. Third, the cross-disciplinary research covering queuing analysis, network measurements, system design, and prototype implementation and deployment sets up an agenda to address real-world network issues.Broader Impact: Guarantees on traffic statistics that a packet pacing architecture can provide are an essential step in the process to convince the Internet community, especially Internet service providers, to adopt and deploy optical networks. A wide-spread adoption of such networks in the U.S. could increase the availability of high-bandwidth data communication and improve wide-spread access to modern communication services and applications.

随着数据通信对我们的社会变得越来越重要，对网络基础设施的需求已经达到期望实现光分组交换核心的程度。大型光缓冲器的高昂成本已经导致许多光网络设计在路由器上具有小缓冲器。这方面的一个主要挑战是设想有效的运作方案，证明这些小型缓冲网络的合理性。该项目旨在开发一种架构，实现网络链路上的数据包间隔，以便确保网络流量的适当统计特性，并有效地运行小缓冲网络。该项目的具体目标是：（1）了解数据包间隔及其对网络范围的影响，（2）开发起搏节点原型，以及（3）考虑网络范围的部署。本计画所开发的封包间隔架构，将有助于推动光封包交换技术的广泛应用。智慧价值：本计画的智慧价值包含三个方面。首先，该研究将进一步了解数据包间隔对整个网络的影响（而不是仅限于单个缓冲区分析）。其次，起搏架构将有助于提高光核心网的运行效率，从而改善整个互联网。第三，跨学科的研究，包括排队分析，网络测量，系统设计，原型实现和部署建立了一个议程，以解决现实世界的网络问题。更广泛的影响：保证流量统计数据，一个包调步架构可以提供的过程中，说服互联网社区，特别是互联网服务提供商，采用和部署光网络的一个重要步骤。在美国广泛采用这种网络可以增加高带宽数据通信的可用性，并改善对现代通信服务和应用的广泛访问。
