Title : Using DHCPv6 for Prefix Delegation in Cellular Networks
Author(s) : B. Sarikaya, F. Xia
Filename : draft-sarikaya-int-area-prefix-delegation-00.txt
Pages : 12
Date : 2009-12-16
According to IPv6 operation in cellular networks, one prefix can only
be assigned to one interface of a mobile node by an access router and
different mobile nodes can't share a prefix. Managing Per-MN
interface prefixes is likely to increase the processing load at the
access router. Based on the idea that DHCPv6 servers can manage
prefixes as well as addresses, we propose a new technique in which
the access router offloads delegation and release tasks of the
prefixes to an DHCPv6 server. The access router first requests a
prefix for an incoming mobile node to the DHCPv6 server. The access
router next advertises the prefix information to the mobile node with
a Router Advertisement message. When the mobile node hands off, the
prefix is returned to the DHCPv6 server. We also describe how AAA
servers can help in prefix delegation.
