Abstract:
1. A method for redialing a broadband access server, the method being performed by execution of computer readable program code by at least one processor of at least one computer system, the method comprising: sending a Point-to-Point Protocol over Ethernet (PPPoE) Active Discovery Terminate (PADT) packet to a broadband access server (BAS) from a client computer upon the condition that the client computer has been abnormally disconnected from the BAS using the at least one processor, wherein the PADT packet comprises identity data of a user of the client computer; determining if the client computer is allowed to perform a redial to the BAS according to the identity data using the at least one processor; in response to the client computer is authorized to perform a prompt redial, sending a responsive PADT packet to the client computer to release on-line resources previously allocated for the client computer in order to end the connection between the client computer and the BAS using the at least one processor; sending a PPPoE Active Discovery Initiation (PADI) packet to the BAS from the client computer using the at least one processor; responding to the PADI packet by sending a PPPoE Active Discovery Offer (PADO) packet to the client computer from the BAS using the at least one processor; sending a PPPoE Active Discovery Request (PADR) packet to the BAS from the client computer using the at least one processor; responding to the PADR packet by sending a PPPoE Active Discovery Confirmation (PADS) packet to the client computer from the BAS so as to create a new connection between the client computer and the BAS using the at least one processor; and discarding the PADT packet sent from the client computer if the client computer is not allowed to perform the prompt redial, subsequently redialing after a predetermined period of time using the at least one processor.
