The Internet Engineering Task Force (IETF) has worked on
network layer mobility for more than 10 years and a number
of RFCs are available by now. Although the IETF mobility
protocols are not present in the Internet infrastructure as of
today, deployment seems to be imminent since a number
of organizations, including 3GPP, 3GPP2 and Wimax, have
realized the need to incorporate these protocols into their architectures.
Deployment scenarios reach from mobility support
within the network of a single provider to mobility support
between different providers and technologies. Current Wimax
specifications, for example, already support Mobile IPv4,
Proxy Mobile IPv4 and Mobile IPv6. Future specifications will
also support Proxy Mobile IPv6. Upcoming specifications in
the 3GPP Evolved Packet Core (EPC) will include the use of
Mobile IPv4, Dual Stack MIPv6 and Proxy Mobile IPv6 for
interworking between 3GPP and non 3GPP networks.
This paper provides an overview on the state-of-the-art
in IETF mobility protocols as they are being considered by
standardization organizations outside the IETF and focusing
on security aspects.
