 While this book is mostly about the Internet, congestion control applies to all packet-oriented networks. Therefore, Chapter 2 is written in a somewhat general manner and explains the underlying principles in a broad way even though they were mainly applied to Internet protocols. This book does not simply say ‘TCP works like this’ – rather, it says ‘mechanism a has this underlying reasoning and works as follows’ in Chapter 2 and ‘this is how TCP uses mechanism a’ in Chapter 3.In this book, there is a clear distinction between things that are standardized and deployed as opposed to things that should be regarded as research efforts. Chapter 3 presents technology that you can expect to encounter in the Internet of today. It consists of two parts: first, congestion control in end systems is explained. In the present Internet, this is synonymous with the word ‘TCP’. The second part focuses on congestion control – related mechanisms within the network. Chapter 4 goes into details about research endeavours that may or may not become widely deployed in the future. Some of them are already deployed in some places, but they have not gone through the IETF procedure for specification and should probably not be regarded as parts of the TCP/IP standard. Topics include enhancements that make TCP more robust against adverse network effects such as link noise, mechanisms that perform better than TCP in high-speed networks, mechanisms that are a better fit for real-time multimedia applications, and RED improvements. The book is all about efficient use of network capacities; on a longer time scale, this is ‘traffic management’. Traffic management tools typically fall into one of two categories: ‘traffic engineering’, which is a means to influence routing, and ‘Quality of Service’ (QoS) – the idea of providing users with differentiated and appropriately priced network services. Both these topics are covered in Chapter 5, but this part of the book is very brief in order not to stray too far from the main subject. After all, while traffic engineering and QoS are related, they simply do not fall in the ‘congestion control’ category. Chapter 6 is specifically written for researchers who are looking for ideas to work on. It is quite different from anything else in the book: while the goal of the rest is to inform the reader about specific technology and its underlying ideas and principles, the intention of this chapter is to show that things are still far from perfect in practice and to point out potential research avenues.
