LINK-LAYER AUTHENTICATION FOR LEGACY NETWORK NODES USING A REMOTE NETWORK ACCESS SERVER

摘要

A method for link layer authentication includes receiving, at an edge network access node, a link layer authentication packet from a client, seeking network access, using a remote NAS agent running on the edge network access node. The method transmits, using a tunneling connection, the link layer authentication packet to a remote NAS in a link layer authentication process. The link layer authentication process exchanges the link layer authentication packet with an authentication server to authenticate the client. The method includes receiving a link layer authentication packet from the remote NAS over the tunneling connection. The received link layer authentication packet includes a response from the authentication server regarding the transmitted link layer authentication packet. The method includes transmitting the received link layer authentication packet to the client and, in response to link layer authentication packets resulting authorization, authorizing the client for network access through the edge network access node.
