Abstract
A Network Access Server incorporates a “hand-off” feature that allows the NAS to transfer an existing PPP connection from one NAS to another NAS. In particular, 3 new control messages are defined for use in the NAS. Namely: (i) Continued Call Request, (ii) Continued Call Reply, and (iii) Continued Call Connect. These 3 new control messages comprise a L2TP control message header, message identifier (e.g., continued call request, etc.), and a number of fields.
