  • Method for preventing IP address from unexpected dispersion when using point-to-point protocol
    Patent number: 8533779
    Abstract: A method for preventing IP address from unexpected dispersion when using point-to-point protocol is disclosed. The method comprises the steps: starting and initializing a PPP session; performing a PPP LCP negotiation, in which times of the successful PPP LCP negotiation is limited; performing a PPP authentication, in which an authentication request to AAA client is sent only once; performing a PPP IPCP negotiation, in which an accounting-start request is sent only once and times of the successful PPP IPCP negotiation is limited; and terminating the PPP session and releasing the IP address. The method of the invention for preventing IP address from unexpected dispersion when using point-to-point protocol effectively avoid excessive oscillation of a LCP state machine and a IPCP state machine by limiting times of the successful PPP LCP negotiation during the period of PPP LCP negotiation and times of the successful PPP IPCP negotiation.
