The datacenter networks we use today are based on a 50-year-old design. While it has served us well, that design no longer meets the needs of today's distributed applications. The result is failures visible to the users of those applications in spite of developers’ best efforts. We believe it is time to provide a new design, one that takes into account what today's applications need. To that end, we have developed a network architecture that starts at the physical layer and extends to the way applications communicate and how they are managed. A key design goal is the ability to recover from network failures so fast that applications perceive an unbreakable network.

弹性数据中心网络的设计

我们今天使用的数据中心网络基于已有 50 年历史的设计。虽然它对我们很有帮助,但这种设计不再满足当今分布式应用程序的需求。结果是尽管开发人员尽了最大努力,但这些应用程序的用户仍会看到失败。我们相信是时候提供一种新设计了,该设计考虑了当今应用程序的需求。为此,我们开发了一种从物理层开始并扩展到应用程序通信方式和管理方式的网络架构。一个关键的设计目标是能够快速从网络故障中恢复,以至于应用程序感知到一个牢不可破的网络。
