Abstract:
In a network implementing Distributed Mobility Management, it has
been agreed that Mobile Nodes (MNs) should exhibit agility in their
use of IP addresses. For example, an MN might use an old address for
ongoing socket connections but use a new, locally assigned address
for new socket connections. Determining when to assign a new
address, and when to release old addresses, is currently an open
problem. Making an optimal decision about address assignment and
release must involve a tradeoff in the amount of signaling used to
allocate the new addresses, the amount of utility that applications
are deriving from the use of a previously assigned address, and the
cost of maintaining an address that was assigned at a previous point
of attachment. As the MN moves farther and farther from the initial
point where an address was assigned, more and more resources are used
to redirect packets destined for that IP address to its current
location. The MN currently does not know the amount of resources
used as this depends on mobility path and internal routing topology
of the network(s) which are known only to the network operator. This
document provides a mechanism to communicate to the MN the cost of
maintaining a given prefix at the MN's current point of attachment so
that the MN can make better decisions about when to release old
addresses and assign new ones.
