The communication path between two Hosts within a Proxy Mobile IPv6
domain is artificially long - it involves the LMA, even if straight
paths exist (under same MAG, or MAG-to-MAG). Localized Routing
PMIPv6-LR concepts developped by NETEXT WG make use of LRI/LRA
messages to achieve optimized MAG-to-MAG straight paths. This may
prove inconvenient for the network operator, in that it may loose
ability to control traffic (LMA control point is skipped).
In this draft we present a middle-ground solution. It employs new
Intermediary Anchors (IAs) in the paths between MAGs and offers
points of control of traffic useful for QoS and lawful interception.
