He introduced the concepts behind TCP / IP and UDP and the use and purpose; provide complete coverage of Java networking APIs, including extended discussions advanced server design, so that various design principles and tradeoffs concerned are discussed and equip the reader with queuing-theory analysis tools to evaluate alternative designs; include UDP multicasting, and includes a multi-homed hosts, leading the reader to understand the extra programming steps and design considerations needed in the environment. After reading this book the reader will have a sophisticated knowledge of network design and basic programming concepts in Java language, which allows them to design and implement distributed applications with advanced features and to predict their performance.
