between multiple protocol layers.
Benefits
Provides a highly secure network hosted private networking service for large enterprises that have data roaming users
that seek remote connectivity solutions to enterprise managed applications. The enterprise HA also provides a cost
effective solution for telemetry applications such as remote meter reading.

Mobile IPv6
Benefits
Enables use of single mobility core network for provisioning of IPv6 and IPv4 Mobile IP access services. Mitigates
IPv4 address depletion concerns for address intensive always-on applications and interactive applications such as VoIP,
video telephony and Push-to-Talk (PTT).

Description
MIPv6 allows a user to maintain a persistent IPv6 address even when handing off between Access Service Networks
(ASNs) connected to different ASN GWs and allows the access device to be reachable via the same MIPv6 Home of
Address (HoA) irrespective of the current point of attachment. A Mobile IPv6 Node (MN) uses two IPv6 addresses:

Address (HoA) irrespective of the current point of attachment. A Mobile IPv6 Node (MN) uses two IPv6 addresses:
Care of Address (CoA) derived from Interface-ID assigned by DHCP Proxy component on ASN GW after verification of
user or device credentials during network access
user or device credentials during network access
Home of Address (HoA) assigned by HA during the Mobile IP registration with home network. The MN registers its
current point of attachment by providing its CoA.
current point of attachment by providing its CoA.
The MN can operate in two modes:
Bidirectional tunnel - In this mode, all data traffic originating from or destined to the MNs MIPv6 HoA is
tunneled via the HA.
Route optimization - In this mode, the MN informs its correspondent node of its current point of attachment,
allowing the correspondent node to directly route packets destined to the MN's HoA through its CoA. Route
optimization will not be supported in this release.

Supported Features
MIPv6 message authentication mobility options in binding updates as per RFC 4285
MN-NAI mobility option in binding messages as per RFC 4283. The MN-NAI option must be included in all Binding
messages (Eg initial registration and subsequent updates).
