The Future of CEF and Packet Switching
Although this book provides solid information for software handling and hardware handling, it does not provide a detailed description of implementation on all Cisco platforms and related technologies. Hardware design changes rapidly, and packet handling on one platform could easily consume the entire book.
This book does not address Parallel Express Forwarding (PXF), which is used on devices such as Cisco 10000 series routers, Cisco 7600 series Optical Service Modules (OSMs), and Cisco 7300 series routers.
