RFC 4284 Identity Selection Hints for EAP January 2006

The Extensible Authentication Protocol (EAP) is defined in RFC 3748. This document defines a mechanism that allows an access network to provide identity selection hints to an EAP peer -the end of the link that responds to the authenticator. The purpose is to assist the EAP peer in selecting an appropriate Network Access Identifier (NAI). This is useful in situations where the peer does not receive a lower-layer indication of what network it is connecting to, or when there is no direct roaming relationship between the access network and the peer’s home network. In the latter case, authentication is typically accomplished via a mediating network such as a roaming consortium or broker. The mechanism defined in this document is limited in its scalability. It is intended for access networks that have a small to moderate number of direct roaming partners. Adrangi, et al.
