Features: For application services provided on the Internet, such as web browsing and instant messaging, best-selling author and internet technology expert Douglas Comer presents a comprehensive overview. Based on the previous edition, this book adds several chapters on internet technologies, explaining the entire knowledge from internet applications to the underlying packet transmission. It demonstrates how protocols are layered and how higher layers utilize layered protocol services. Written by best-selling author and computer networking expert Douglas Comer, the book is divided into five parts. Part I outlines the use and construction of Internet applications; Part II covers the knowledge of data transmission, including transmission media, local asynchronous communication, and long-distance communication. Part III discusses packet switching, introducing next-hop routing, switching, and protocol layering after describing various network characteristics, and details the process of packet switching with Ethernet, FDDI, token ring, and ATM. Part IV focuses on network interconnection, primarily introducing the TCP and ARP protocols. Part V covers network applications, starting with the client/server model, describing the Domain Name System (DNS) and domain name resolution in applications, file transfer, and web browsing, including explanations and applications of dynamic CGI documents and active Java documents. This book is suitable for senior undergraduate students in computer science and low-graduate students lacking network knowledge.
