Date :2009-06-01 Version 3. The first two editions of the book is based on the developments of computer networks. streamlining some of the content. adding new technology. fully about the computer network technology. First introduce the architecture of computer networks. and then the physical layer. data link layer. network layer. transport layer and application layer architecture of five layers of the main line about the basic principles of computer networks and core technologies. and finally introduce network security technology. This book tells the network focus on the basic concepts and principles. which are the most important learning network technology knowledge points. but also seeks to reflect the development of new computer network technology. Book is aimed at institutions of higher education science and engineering undergraduate computer networking class curriculum. but also as objects of other professional and other teaching materials and engineering and technical personnel engaged in research and development work of reference.
