COMPUTER NETWORKS : PERFORMANCE & QUALITY OF SERVICE
FOR UPSC, SSC, RAILWAYS, NDA, CDS & STATE PCS, IAS, IBPS, CAT.
This book reviews modern computer networks with a focus on performance and quality of service. Wired and wireless/mobile networks today are working in concert and need to be studied together, rather than separately. Multimedia applications are ever more important and need to be given adequate representation relative to traditional data applications. This book covers these topics with an emphasis on underlying principles and core concepts. Audience This book is designed for upper-division undergraduate and graduate courses in computer networking. By focusing on explanations rather than collections of facts, it is intended primarily for learning, rather than reference. The book’s focus on basic concepts should also be appealing to practitioners interested in the “whys” behind the commonly encountered networking technologies. The reader should have basic knowledge of probability and statistics (reviewed in the Appendix). Most concepts do not require mathematical sophistication beyond a first undergraduate course. I tried to present a serious material in a fun way so the reader may take pleasure in learning something nontrivial. It is never easy, but I hope it will be worth your effort. Approach and Organization |
| Computer networks |
In structuring the text, I faced the choice between logically grouping the topics vs. gradually identifying and addressing issues. The former creates a neater structure and the latter is more suitable for teaching new material. I compromised by opportunistically adopting both approaches. Chapter 1 reviews essential networking technologies. It is condensed but more technical than many current networking books. I tried to give an engineering overview that is sufficiently detailed but not too long. This chapter serves as the basis for the rest of the book. I believe that it may also suffice for an introductory course on computer networks. Chapter 2 reviews end-to-end mechanisms for congestion management in data networks. Most of these mechanisms are implemented in different variants of Transmission Control Protocol (TCP), which is the most popular Internet protocol. Chapter 3 reviews the requirements and solutions for multimedia networking. It describes esirable network behaviors, rather than detailed mechanisms for implementing such behaviors. Such mechanisms are described in Chapter 5, after the operation of network routers is detailed in Chapter 4. Chapter 4 describes how network routers forward data packets. It also describes simple techniques for modeling queuing delays in routers. Chapter 5 describes router techniques for reducing or redistributing queuing delays across data packets belonging to different flows. These include scheduling and policing the network traffic. This chapter also reviews the MPLS protocol that is particularly important to network operators.
