Method for providing virtual private network services to mobile node in IPv6 network and gateway using the same |
摘要 |
Provided are a method for providing virtual private network (VPN) services to a mobile node (MN) in an IPv6 network and a gateway using the same. The method includes: performing IKE (Internet key exchange) negotiation with an MN (mobile node) which has performed handover, acquiring SA (security association) and then authenticating a terminal of the MN; receiving a BU (binding update) message from the MN and verifying the BU message, storing new position information of the MN, transmitting a BA (binding acknowledgement) message and performing mobility processing; if the mobility processing is completed, performing IPsec processing on packets which the MN transmits to a CN (correspondent node), and transmitting the packets; and re-configuring and transmitting packets so that packets which the CN transmits to a home address of the MN can be transmitted to a CoA (Care-of-Address) of the MN. A function performed by a home agent (HA) of Mobile IPv6 is performed so that IP mobility in VPN services can be provided and both mobility inside a VPN domain of the MN and mobility outside the VPN domain can be supported.
