LiveLessons – How Networks Really Work

网络系统有许多元素，包括主机、虚拟主机、路由器、虚拟路由器、路由协议、发现协议等。每个协议和设备（无论是虚拟的还是物理的）通常都作为一个单独的“事物”来研究。将所有这些部分视为系统的组件，这些部分协同工作以通过网络传输流量，这并不常见。为了展示所有这些组件如何协同工作以形成一个完整的系统，本视频课程展示了一系列演练，展示了各种网络事件所涉及的处理，以及控制平面如何使用这些事件来构建传输流量所需的信息一个网络。

作为最重要的互联网专家之一，Russ White 利用他在 Cisco、LinkedIn 和 Juniper 等大型网络构建和故障排除方面的数十年经验，向您展示了一种经过验证的方法，可帮助您了解网络技术为何以及如何工作。您将学习考虑正在解决的具体问题、选择具体解决方案的原因以及解决方案之间的关系。除了提供对许多常见协议和解决方案的全面概述之外，这种有价值的见解还可以帮助您培养理解为什么应该做出特定实施决策以及在每种情况下的权衡取舍的能力，通过了解每种技术的工作原理来提高您的故障排除技能以及任何解决方案可能会出现什么问题，

该课程从发现主机发送流量所需的信息和网络设备内的转发过程开始。第一次演练很简单，但在解释了通过硬件优化转发平面在覆盖中承载的流量之前，它们将变得复杂。一路走来，控制平面必须解决的四个问题将与解决这些问题的常用解决方案一起暴露出来。在介绍了这些基本信息之后，将考虑更高级的情况，包括从控制平面角度来看的网络弹性和快速重新路由技术。

There are many elements to a networking system, including hosts, virtual hosts, routers, virtual routers, routing protocols, discovery protocols, etc. Each protocol and device (whether virtual or physical) is generally studied as an individual “thing.” It is not common to consider all these parts as components of a system that works together to carry traffic through a network. To show how all these components work together to form a complete system, this video course presents a series of walk throughs showing the processing involved in various kinds of network events, and how control planes use those events to build the information needed to carry traffic through a network.

One of the foremost internetworking experts, Russ White leverages his decades of experience in building and troubleshooting large scale networks at the likes of Cisco, LinkedIn, and Juniper to present you with a proven methodology that will help you understand why and how networking technologies work. You will learn to consider the specific problems being solved, why specific solutions are chosen, and how solutions relate to one another. In addition to providing a solid overview of many common protocols and solutions, this valuable insight helps you develop the ability to understand why you should make particular implementation decisions and what the tradeoffs are in each situation, enhance your troubleshooting skills by understanding how each technology works and what problems might arise with any solution, and finally to quickly understand new technologies as they are released by relating them to previously developed technologies.

The course begins with the discovery of the information a host needs to send traffic and the forwarding process within a network device. The first walk through is simple, but they will build in complexity until traffic carried in an overlay through a hardware optimized forwarding plane is explained. Along the way, the four problems a control plane must solve will be exposed along with the solutions commonly used to solve these problems. After this basic information is covered, more advanced situations will be considered, including network resilience from a control plane perspective and fast reroute techniques.

About the Instructor

Russ White began working with computers in the mid-1980s, and computer networks in 1990. He has experience in designing, deploying, breaking, and troubleshooting large scale networks, and is a strong communicator from the white board to the board room. Across that time, he has co-authored more than forty software patents, participated in the development of several Internet standards, helped develop the CCDE and the CCAr, and worked in Internet governance with the Internet Society. Russ has a background covering a broad spectrum of topics, including radio frequency engineering and graphic design, and is an active student of philosophy and culture.
