课程名称：云网络 课程概述： 在此云网络课程中，我们将探讨网络在云计算中所需的功能。课程将通过与行业领先专家的对话，加深对当前实践的理解，并关注可能影响云网络未来的新研究。我们将深入研究云网络面临的挑战，例如如何建立一种能够在共享基础设施上部署虚拟网络、有效传输大数据和实现低延迟通信的网络架构，如何使应用跨越国家和大陆进行联邦化。 本课程强调操作和设计原理两个方面，即系统是如何运作的以及为何这样设计。我们期待与您一起进入这一课程，共同探讨现代应用程序关键通信基础设施的内在运作。 课程大纲： 第一部分：第一周 我们将首先观察数据中心中运行的应用程序及其产生的流量模式。这将帮助我们区分数据中心内的网络需求与一般计算机网络的不同，并为后续材料奠定基础。接着，我们将深入学习物理网络结构，探讨数据中心对带宽的日益需求如何影响网络设计。 第二部分：第二周 本周，我们将进一步研究数据中心网络堆栈，关注物理和虚拟机器的路由与交换以及拥塞控制。我们将考察路由在此环境中需解决的问题及其实际解决方案。还将探讨网络如何更深入地进入物理主机，以满足虚拟机器的网络需求。此外，我们将了解TCP拥塞控制在数据中心面临的问题及其应对方法。 第三部分：第三周 本周聚焦云数据中心网络基础设施的管理和共享。传统网络技术需要复杂且容易出错的配置，且在多个租户之间安全共享网络的难度较大。我们将学习软件定义网络和网络虚拟化如何解决这些问题。 第四部分：第四周 跳出数据中心，本周将考察云网络生态系统的其他部分：数据中心间的广域网连接、内容分发网络、终端用户互联网连接，以及应用程序与网络的交互。我们将了解各领域中的新技术如何推动云的能力更进一步。 第五部分：第五周 - 编程作业提交 本模块将不包含新内容。您可以在此处找到有关编程作业的所有信息，并在这里提交您的作业。
Part: 1
Title:Week 1
Description:We will start by looking at the applications running in data centers and the traffic patterns resulting from them. This will help us differentiate the networking needs within data centers from computer networking in general and set the stage for other material in the course. We’ll then dive into the first of these topics, physical network structure, where we will look at how the increasing demand for bandwidth within data centers is influencing the network’s design.
Part: 2
Title:Week 2
Description:This week, we will dive further into the data center network stack, looking at routing and switching for physical and virtual machines and congestion control. We’ll examine what concerns routing needs to address in these environments and how it’s done in practice. We’ll also see how the network is moving deeper into the physical hosts in order to address the networking needs of virtual machines. With regards to congestion control, we’ll learn what problems TCP’s congestion control faces in data centers and how these are being addressed.
Part: 3
Title:Week 3
Description:This week focuses on management and sharing of network infrastructure in cloud data centers. Traditional networking technologies require complex, error-prone network configuration, and make sharing of the network across multiple tenants in a secure manner difficult. We’ll learn how software-defined networking and network virtualization are addressing these problems.
Part: 4
Title:Week 4
Description:Zooming out from within data centers, this week will examine other pieces of the cloud networking ecosystem: inter-data center WAN connectivity, content distribution networks, end-user Internet connectivity, and application interactions with the network. We’ll learn what novel techniques in each of these areas are pushing the cloud’s capabilities farther.
Part: 5
Title:Week 5 - Programming Assignment Submission
Description:There is no new content in this module. You can find all the information about the programming assignments here, as well as submit your programming assignments here.
In the cloud networking course, we will see what the network needs to do to enable cloud computing. We will explore current practice by talking to leading industry experts, as well as looking into interesting new research that might shape the cloud network’s future. This course will allow us to explore in-depth the challenges for cloud networking—how do we build a network infrastructure that provides the agility to deploy virtual networks on a shared infrastructure, that enables both efficient transfer of big data and low latency communication, and that enables applications to be federated across countries and continents? Examining how these objectives are met will set the stage for the rest of the course. This course places an emphasis on both operations and design rationale—i.e., how things work and why they were designed this way. We're excited to start the course with you and take a look inside what has become the critical communications infrastructure for many applications today.
