Hi Curtis,

All packets hit the ESP, they are the backbone of the ASR1000. Just like the RSP in the ASR9000 and the SCB in the J-MX, etc. etc.

Did a quick Google, there are a couple of useful pictures and words on this page, though others may have links to better docs/training materials. I used to have some someplace but use ASR9000s almost exclusively these days if I’m doing Cisco, and have misplaced them..
