IOS architecture

You might want to take a look at the CEF book, which expands on this
http://www.amazon.com/Cisco-Express-Forwarding-ebook/dp/B0015V9DQU/

both of these are still very accurate on how IOS operates today. The
only major changes with IOS-XE is that IOS is now a process and packet
forwarding is handled in hardware instead of software.

For NX-OS and IOS-XR the software/operating system is wildly different
and I think there is a definite gap in literature out there.
