项目摘要

Self-organizing overlay networks have emerged as a powerful new paradigm for deploying network services on a large scale, yet the full potential of this technology remains largely unexplored. This project will advance the state-of-the-art of self-organizing virtual overlay networks and show that design principles for self-organizing networks can be evolved into a blueprint for a new protocol architecture for future communication networks and services. We will develop algorithms and protocols for a network architecture that is entirely based on the principles of self-organizing overlay networks. Using analytical methods, simulation, and measurements of testbed implementations we will provide new insights into the capabilities and limitations of self-organizing networks. A key challenge addressed in this project is the development of algorithms and protocols that can maintain a connected overlay graph in the presence of multiple heterogeneous substrate networks. To show that self-organizing networks can deliver high delay and throughput performance at the lower layers of the system architecture, we propose the development of an `overlay switch' with hardware support for self-organizing overlay network protocols. We will explore algorithms that enable overlay networks to scale to millions of nodes. In addition, we will devise and evaluate algorithms for overlay networks that result in an efficient use of network resources.

自组织覆盖网络已成为大规模部署网络服务的强大新范式，但该技术的全部潜力仍然没有探索。该项目将推进自组织虚拟覆盖网络的最新作品，并表明可以将自组织网络的设计原理演变为用于未来通信网络和服务的新协议体系结构的蓝图。我们将为网络体系结构开发算法和协议，该网络体系结构完全基于自组织覆盖网络的原理。使用分析方法，仿真和测量实现实现的测量，我们将提供有关自组织网络能力和局限性的新见解。该项目中提出的一个关键挑战是开发算法和协议，这些算法和协议可以在存在多个异质基板网络的情况下维护连接的覆盖图。为了表明，自组织网络可以在系统体系结构的下层提供高延迟和吞吐量性能，我们提出了“覆盖开关”的开发，并在硬件支持上支持自组织覆盖网络协议。我们将探索使覆盖网络扩展到数百万节点的算法。此外，我们将设计和评估覆盖网络的算法，从而有效利用网络资源。
