1) AH is Authentication Header : It provides only Authentication & no
Encryption. It provides Authentication to both IP layer as well as Upper

2) ESP is Encapsulation Security Payload : It provides optional
Authentication as well as optional Encryption. One of the service MUST be
selected. It provides these services Upper layer protocols & not IP layer.
