Charles E. Spurgeon is the senior network architect at the University of Texas at Austin. He has worked on large campus networks for over 30 years, beginning in 1979 when he used to "test" network equipment by using it to read the Science Fiction Lover's Digest over the ARPANET. In the 1980s he helped develop the Stanford University network, which included building a number of prototype Cisco Systems routers and linking them together with Xerox PARC's experimental Ethernet running at 3 Mbps. In 1994, he created what is widely acknowledged as the most comprehensive and popular Ethernet web site. Charles, who attended Wesleyan University, lives in Austin, Texas with his wife, Joann Zimmerman. In his spare time he reads seafaring novels, science fiction, mysteries, and anything else he can find on the shelves of their 4,000 volume home library. This is his third book on Ethernet.
