ISAKMP (Internet Security Association and Key Management Protocol) is a protocol for establishing Security Associations (SA) and cryptographic keys in a internet environment.
ISAKMP defines the procedures for authenticating a communicating peer, creation and management of Security Associations, key generation techniques, and threat mitigation (e.g. denial of service and replay attacks).
ISAKMP typically utilizes IKE for key exchange, although other methods can be implemented.
ISAKMP is documented in RFC 2048: Internet Security Association and Key Management Protocol (ISAKMP).
ISAKMP under IP (Internet Protocol) is documented in RFC 2407: The Internet IP Security Domain of Interpretation for ISAKMP.

Which OSI layer does ISAKPM operate at. The following link says it operates at the application layer: http://www.networksorcery.com/enp/protocol/isakmp.htm (see protocol type near the top of the page).
This link says it operates at the session layer: http://wiki.answers.com/Q/What_protocols_are_at_the_TCP-IP_application_layer
What do you think?

I could argue either way. In intent, it operates at the Session Layer. In actual implementation, it operates at the Application Layer.
