Abstract
A Passive Optical Network (PON) includes an Optical Network Terminal (ONT) and an Optical Line Terminal (OLT). The ONT is configured for providing controlled port operations of authenticator Port Access Entity (PAE) functionality and the OLT is configured for providing entity authentication operations of the authenticator PAE functionality. The controlled port operations of authenticator PAE functionality includes inhibiting transmission of non-authentication messages from the ONT, transmitting a supplicant authentication request to the OLT and enabling transmission of non-authentication messages from the ONT in response to receiving supplicant authentication confirmation. The entity authentication operations of the authenticator PAE functionality include facilitating authentication of an identity of the supplicant and facilitating transmission of supplicant authentication confirmation for reception by the ONT in response to the identity being authenticated.
