eap Mailing List: Re: Issue 348: Definition of Lower Layer

[Bernard Aboba (bernard_aboba]

RFC 3748 Section 2.2 says:

"Lower layer.  The lower layer is responsible for transmitting and
receiving EAP frames between the peer and authenticator."

How would this do as a definition of Lower Layer?

Rationale/Explanation of issue:

I just looked up RFC3748 and the EAP Keying Framework and realized that
there isn't a definition for the term "lower layer". I would recommend
adding a definition to the terminology section of the keying framework
draft. Lower layer, to me means the layer over which EAP runs. Between
the peer and the authenticator, this would be the layer that runs the
secure association protocol to derive TSKs, while between the
authenticator and the AS, this would be the AAA protocol carrying EAP,
for instance.
