Over the past two decades, the Internet has grown from a research curiosity to something we all rely on daily. It has been able to withstand rapid growth and accommodate numerous unforeseen applications.

在过去的二十年中，互联网从一个研究兴趣项目发展成我们每天依赖的事情。它可以顶住快速发展的世界，同时适应很多不能预见的应用。

How does this global infrastructure work? What design principles allow it to scale well? What settings render these principles inadequate, and why? How can we make it work much better in the future? These are some questions that we will address in this course.

互联网整体架构是如何工作的？是什么设计原则使得它具有很好的扩展性？是什么环境导致这些原则不适用，为什么？我们可以做些什么使得互联网工作的更好？在这个课程中我们会解答其中一些问题。

Our goals are:

to understand a good slice of the state-of-the-art in network architecture, protocols, and networked systems, and

to understand how to conduct networking research and develop innovative ideas.
