PPP Design, Implementation, and Debugging, 2nd Edition

PPP Design, Implementation, and Debugging, Second Edition is a complete and convenient resource for network system designers and administrators. This book contains everything you need to know to work with the Point-to-Point Protocol (PPP), one of the most important Internet protocols in use today. Inside you'll find clear explanations of the underlying concepts, practical implementation information, and valuable debugging techniques to keep your PPP connections running smoothly, efficiently, and without interruption. Extensively revised and expanded to cover the latest developments in PPP and network technology, this Second Edition addresses such current topics as: * PPP in today's telecommunications infrastructure * PPP and telephony * Optical (SONET/SDH) PPP links * The relationship between PPP and routing protocols (such as OSPF) * Security services, including RADIUS * PPP and L2TP virtual private networks * The design of the popular ANU ppp-2.3 implementation PPP Design, Implementation, and Debugging, Second Edition provides an overview of PPP design and operation, and follows PPP in detail through each of its three main stages–link establishment, authentication, and data transmission. Each PPP protocol is described in depth, including LCP (Link Control Protocol), CCP (Compression Control Protocol), and ECP (Encryption Control Protocol). PPP's relationship to other networking protocols is also examined. In addition, this book offers an experience-based troubleshooting guide that describes proven solutions to common PPP problems.
