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.

自组织覆盖网络已经成为大规模部署网络服务的一种强大的新范式，但这项技术的全部潜力在很大程度上仍未得到开发。该项目将推进自组织虚拟覆盖网络的最新发展，并表明自组织网络的设计原则可以演变为未来通信网络和服务的新协议体系结构的蓝图。我们将为完全基于自组织覆盖网络原理的网络体系结构开发算法和协议。使用分析方法、模拟和对试验台实施的测量，我们将对自组织网络的功能和局限性提供新的见解。该项目中解决的一个关键挑战是开发能够在存在多个异质衬底网络的情况下维护连接覆盖图的算法和协议。为了证明自组织网络可以在系统体系结构的较低层提供高延迟和高吞吐量性能，我们提出了一种具有硬件支持的自组织覆盖网络协议的覆盖交换机的开发。我们将探索使覆盖网络能够扩展到数百万个节点的算法。此外，我们还将设计和评估覆盖网络的算法，以实现网络资源的高效利用。
