NEGOTIATING DIFFERENT MOBILE IP DELIVERY STYLES

摘要

The present invention provides a system and method to selectively negotiate different delivery styles for different types of packets sent from the Mobile Node to the Foreign Agent, which will allow the Mobile Node to negotiate a delivery style that will permit the Foreign Agent to transmit certain selected outbound traffic directly without reverse tunneling that traffic back to the home network. Specifically, the present invention allows the Foreign Agent to distinguish between certain types of BC/MC packets that are designated to be processed and routed to their destinations by the Foreign Network directly, as opposed to reverse tunneling the outbound traffic from the Foreign Agent back to the Home Agent on the home network. By selecting processing by the Foreign Network, the efficiency of the system will improve because the transmission of outbound traffic and inbound responses will not need to be tunneled through the Home Network.
