Description: With the increasing number of telecommuters and people who are mobile, remote access is now a vital part of an organizations network. The new L2TP protocol (Layer 2 Tunneling Protocol) gives enterprises unprecedented flexibility in providing cost-effective remote access. This book goes far beyond the standards documents, giving crucial information on writing L2TP code and on using L2TP for VPN deployment. Readers will discover how to implement L2TP and how L2TP addresses serious limitations in today's approaches to virtual remote access. They will also learn how L2TP can enable support for high-speed remote access via cable modems and ADSL. The book offers a step-by-step introduction to the basics of L2TP layers and protocol structures, and how it integrates with other VPN technologies. Shea provides new insights into session setup; data handling; security; and standards-based (SNMP) network management. It will be invaluable to network engineers developing remote access and VPN code and products; ISPs offering VPN services; and network professionals who need better remote access solutions.
