I just checked the straight dope on SSR (Strict Source Route).
See RFC 791 (Sept 1981).

The ``official'' name of the option is SSRR:
Strict Source and Record Route.

And I was right in class this morning. 
Forouzan is still wrong.

Feel free to check it out! 

Reading an ``ancient'' RFC occasionally is fun!
