A professional reference that examines the gigabit per second computer networks that make it possible to share vast quantities of data among many computer systems. Key technologies, important protocols and applications, and the practical issues involved in implementing gigabit networks are all addressed, and where research is still incomplete, important unsolved issues are presented. Could also be used as a textbook for a graduate course on gigabit networking. Annotation copyright by Book News, Inc., Portland, OR

Gain hands-on experience of CCNP Support topics with lab scenarios aligned to the CIT course Real-word practice labs for each topic included in the CCNP Support exam complement theoretical study materials Guides how to set up a test lab or walk through the screen shots to solve real world situations Lab scenarios enable readers to test their ability to independently complete a lab Comprehensive appendix lists Cisco equipment resellers "CCNP Practical Studies: Support prepares readers for the CCNP Support exam and real-world application of LAN and WAN technologies through a series of lab scenarios. A guide to gaining hands-on experience, this title can serve as a valuable self-study element in a CCNP candidate's preparation. Each chapter includes a review of the applicable technology along with one or more real-world trouble tickets that are delivered through screen shots of relevant troubleshooting commands. Screen shots emphasize important concepts and trouble spots as required. Chapters suggest additional references such as utilities, web sites, and/or supplemental reading. All of the topics in the CCNP Support exam are covered in this book. Each chapter addresses a section of the CCNP Support exam, including IP, IPX, Ethernet, Frame Relay, ISDN, Dial, Cat, and vLANs. For those lacking the lab equipment to practice on, this title highlights the steps needed to accomplish various crucial tasks, providing concrete examples for the challenges faced in real-world configuration.
