What are the main topics covered in the book?
The book is organized into 11 chapters, each covering a major topic in communication networks. Here is a brief summary of what each chapter covers:
Chapter 1: Introduction
This chapter introduces the basic concepts and terminology of communication networks, such as network architectures, protocols, services, interfaces, standards, etc. It also discusses the historical evolution and current trends of communication networks, such as circuit-switched networks, packet-switched networks, internet, broadband networks, wireless networks, etc.
Chapter 2: Layered Architecture
This chapter describes the layered architecture model that is widely used to design and implement communication networks. It explains the advantages of using a layered approach, such as modularity, interoperability, scalability, etc. It also introduces the two most popular layered architectures: the Open Systems Interconnection (OSI) model and the Internet Protocol Suite (TCP/IP) model. It compares and contrasts the two models in terms of their layers, functions, protocols, and applications.
Chapter 3: Physical Layer
This chapter discusses the physical layer functions and technologies that are responsible for transmitting and receiving bits over a physical medium. It covers topics such as signal encoding and decoding, modulation and demodulation, multiplexing and demultiplexing, transmission media characteristics and types, transmission impairments and errors, error detection and correction techniques, etc.
Chapter 4: Data Link Layer
This chapter explains the data link layer protocols and services that are responsible for transferring frames over a single link. It covers topics such as framing and synchronization, flow control and error control techniques, link layer addressing and addressing resolution protocols, link layer switching and bridging techniques, etc.
Chapter 5: Medium Access Control Sublayer
This chapter analyzes the medium access control sublayer techniques and standards that are responsible for coordinating the access of multiple nodes to a shared medium. It covers topics such as channel allocation techniques (static vs dynamic), multiple access protocols (ALOHA, CSMA/CD, CSMA/CA), local area network (LAN) standards (Ethernet, Token Ring, FDDI), wireless LAN standards (IEEE 802.11), etc.
Chapter 6: Network Layer
This chapter presents the network layer functions and algorithms that are responsible for routing packets across multiple links and networks. It covers topics such as network layer addressing and address resolution protocols (IP address, ARP), network layer forwarding techniques (datagram vs virtual circuit), routing algorithms (distance vector vs link state), routing protocols (RIP, OSPF, BGP), multicast routing protocols (DVMRP, PIM), etc.
Chapter 7: Transport Layer
This chapter explores the transport layer protocols and mechanisms that are responsible for providing reliable and efficient end-to-end communication between applications. It covers topics such as transport layer services and primitives (connection-oriented vs connectionless), transport layer addressing and port numbers (TCP/UDP port numbers), transport layer reliability techniques (retransmission strategies, sliding window protocols), transport layer congestion control techniques (TCP congestion control algorithms), etc.
Chapter 8: Application Layer
This chapter surveys the application layer services and applications that are responsible for providing specific functionalities to users over communication networks. It covers topics such as client-server model vs peer-to-peer model, domain name system (DNS), electronic mail (SMTP, POP3, IMAP), world wide web (HTTP), file transfer protocol (FTP), remote login protocol (TELNET), remote procedure call protocol (RPC), etc.
Chapter 9: Network Security
This chapter introduces the network security concepts and methods that are responsible for protecting communication networks from various threats and attacks. It covers topics such as security requirements and goals (confidentiality, integrity, availability), security threats and attacks (passive vs active attacks), security mechanisms and tools (encryption algorithms, digital signatures, certificates), security protocols and standards (IPSec, SSL/TLS, Kerberos), etc.
Chapter 10: Quality of Service
This chapter examines the quality of service requirements and solutions that are responsible for providing different levels of service quality to different applications over communication networks. It covers topics such as quality of service parameters and metrics (delay, jitter, loss rate, bandwidth), quality of service models and architectures (integrated services vs differentiated services), quality of service mechanisms and techniques (traffic shaping, packet scheduling, admission control, Chapter 11: Multimedia Networking
This chapter reviews the multimedia networking challenges and technologies that are responsible for supporting multimedia applications over communication networks. It covers topics such as multimedia data characteristics and types (audio, video, image), multimedia compression techniques and standards (JPEG, MPEG, MP3), multimedia streaming techniques and protocols (RTSP, RTP), multimedia conferencing techniques and protocols (H.323, SIP), etc.
