Förfarande för överförande av data från en server för virtuellt privatnät till en mobilnod

摘要

A method of transmitting data from a Virtual Private Network ("VPN") server to a Mobile Node ("MN") is provided. Upon sensing generation of data destined for the MN in the VPN server, a Customer Premise Equipment ("CPE") router requests an Internet Service Provider ("ISP") router connected to a VPN to search for an address of a Foreign Agent ("FA") to which the MN belongs. The ISP router searches for the FA address through a Home Agent ("HA") and routes the data to the FA identified by the searched FA address. The FA then locates the MN and forwards the data to the MN.
