更新特点

更新特点

• 平衡的介绍侧重于互联网作为网络的一个具体的激励性例子也向学生介绍了更多理论背景下的协议。

• 更新- 扩大和大幅更新的覆盖面反映了软件定义的网络SDN的重要性迅速上升以及4G/5G网络和它们所支持的移动应用的快速采用–可以说是几十年来网络领域最重要和最令人兴奋的进步。

• 更新–个别章节已经更新以反映计算机网络领域的变化。

  • 第1章已经更新以反映互联网和4G/5G网络不断增长的范围和使用。

  • 涵盖应用层的第2章已大幅更新包括有关网络的新HTTP/2和HPPT/3协议的材料。

  • 第3章进行了更新以反映过去五年中传输层拥塞控制和错误控制协议的进展和使用的演变。更新的内容包括扩大对TCP CUBIC的研究它是许多部署的系统中默认的TCP协议以及基于延迟的拥堵控制方法包括新的BBR协议它被部署在谷歌的骨干网络中。另外还研究了QUIC协议该协议正在被纳入HTTP/3标准中。

  • 第4章涵盖了网络层数据平面对其进行了全面的更新。 其中包括一个关于所谓 "中间盒 "的新章节它执行网络层功能而不是路由和转发如防火墙和负载平衡。及时收录了一些新材料如网络路由器中 "恰到好处 "的缓冲量、网络中立性和互联网的架构原则等话题。

  • 第5章涵盖了网络层的控制平面包含了关于SDN的最新材料以及对网络管理的全新处理。SDN的使用已经超越了包转发表的管理也包括网络设备的配置管理。本书介绍了两个新的协议NETCONF和YANG它们的采用和使用推动了这种新的网络管理方法。

Computer Networks andthe Internet Today’s Internet is arguably the largest engineered system ever created by mankind.

with hundreds of millions of connected computers, communication links, and switches: with billions of users who connect via laptops, tablets, and smartphones; and with an array of new Internet-connected "things"including game consoles, sur-

veillance systems, watches, eye glasses. thermostats, and cars. Given that the Inter-

net is so large and has so many diverse components and uses, is there any hope of understanding how it works? Are there guiding principles and structure that canprovide a foundation for understanding such an amazingly large and complex sys-

tem? And if so, is it possible that it actually could be both interesting and fun to learn about computer networks? Fortunately, the answer to all of these questions is a resounding YES! Indeed, it’s our aim in this book to provide you with a modernintroduction to the dynamic field of computer networking, giving you the princi-

ples and practical insights you’ ll need to understand not only today’s networks. but tomorrow’s as well.

This first chapter presents a broad overview of computer networking and the Internet. Our goal here is to paint a broad picture and set the context for the rest of this book. to see the forest through the trees. We’ ll cover a lot of ground in this introductory chapter and discuss a lot of the pieces of a computer network, without losing sight of the big picture We’ ll structure our overview of computer networks in this chapter as follows.

After introducing some basic terminology and concepts, we’ ll first examine the basic hardware and software components that make up a network. We’ ll begin at the net-

work’s edge and look at the end systems and network applications running in thenetwork. We’ ll then explore the core of a computer network, examining the links and the switches that transport data, as well as the access networks and physical media that connect end systems to the network core. We’ ll learn that the Internet is a network of networks, and we’ ll learn how these networks connect with each other After having completed this overview of the edge and core of a computer net work, we’ ll take the broader and more abstract view in the second half of this chap ter. We’ ll examine delay, loss, and throughput of data in a computer network and provide simple quantitative models for end-to-end throughput and delay: models that take into account transmission, propagation, and queuing delays. We’ ll ther introduce some of the key architectural principles in computer networking, namely, protocol layering and service models. We’ ll also learn that computer networks are vulnerable to many different types of attacks: we’ ll survey some of these attacks and consider how computer networks can be made more secure. Finally, we’ ll close this chapter with a brief history of computer networking

1.1 What Is the Internet?

In this book, we’ ll use the public Internet, a specific computer network, as our prin-

cipal vehicle for discussing computer networks and their protocols. But what is the Internet? There are a couple of ways to answer this question. First, we can describe the nuts and bolts of the Internet, that is, the basic hardware and software components that make up the Internet. Second, we can describe the Internet in terms of a network-

ing infrastructure that provides services to distributed applications. Let’s begin with the nuts-and-bolts description, using Figure 1.1 to illustrate our discussion.

1.1.1 A Nuts-and-Bolts Description The Internet is a computer network that interconnects billions of computing devices throughout the world. Not too long ago, these computing devices were primarily traditional desktop computers. Linux workstations, and so-called servers that store and transmit information such as Web pages and e-mail messages. Increasingly however, users connect to the Internet with smartphones and tablets today, close to half of the world’s population are active mobile Internet users with the percentage expected to increase to 75% by 2025 [ Statista 2019. Furthermore, nontraditional Internet "things"such as TVs, gaming consoles, thermostats, home security systemshome appliances, watches, eye glasses, cars, traffic control systems, and more arebeing connected to the Internet. Indeed, the term computer network is beginning to sound a bit dated, given the many nontraditional devices that are being hooked up to the Internet. In Internet jargon, all of these devices are called hosts or end systems By some estimates, there were about 18 billion devices connected to the Internet ir

2017, and the number will reach 28.5 billion by 2022 [ Cisco VNI 2020].
