TCP/IP详解卷2:实现(英文版)

TCP/IP Illustrated, and ongoing series covering the many facets of TCP/IP, brings a highly-effective visual approach to learning about this networking protocol suite. TCP/IP Illustrated, Volume 2: The Implementation contains a thorough explanation of how TCP/IP protocols are implemented. There isn't a more practical or up-to-date book-this volume is the only one to cover the de facto standard implementation from the 4.4BSD-Lite .release, the foundation for TCP/IP implementations run daily on hundreds of thousands of systems worldwide.
