今天的IP网络需要大量的工作来配置和管理。以太网管理起来简单得多，但不能扩展到小型局域网之外。本文描述了一种称为SEATTLE的替代网络体系结构，它实现了两全其美：IP的可伸缩性与以太网的简单性相结合。SEATTLE通过平面寻址提供即插即用功能，同时通过最短路径路由和基于哈希的主机信息解析确保可扩展性和效率。与之前基于身份的路由相比，SEATTLE确保了路径的可预测性和稳定性，并简化了网络管理。我们在真实世界的流量轨迹和网络拓扑驱动下进行了模拟研究，并使用Emulab来评估基于Click和XORP开源路由平台的设计原型。我们的实验表明，SEATTLE有效地处理网络故障和主机移动性，同时与以太网桥接相比，减少了大约两个数量级的控制开销和状态需求。
IP networks today require massive effort to configure and manage. Ethernet is vastly simpler to manage, but does not scale beyond small local area networks. This paper describes an alternative network architecture called SEATTLE that achieves the best of both worlds: The scalability of IP combined with the simplicity of Ethernet. SEATTLE provides plug-and-play functionality via flat addressing, while ensuring scalability and efficiency through shortest-path routing and hash-based resolution of host information. In contrast to previous work on identity-based routing, SEATTLE ensures path predictability and stability, and simplifies network management. We performed a simulation study driven by real-world traffic traces and network topologies, and used Emulab to evaluate a prototype of our design based on the Click and XORP open-source routing platforms. Our experiments show that SEATTLE efficiently handles network failures and host mobility, while reducing control overhead and state requirements by roughly two orders of magnitude compared with Ethernet bridging.
