This document proposes unified Layer 2 (L2) abstractions for Layer 3
(L3)-driven fast handovers.  For efficient network communication, it
is vital for a protocol layer to know or utilize other layers'
information, such as the form of L2 triggers.  However, each protocol
layer is basically designed independently.  Since each protocol layer
is also implemented independently in current operating systems, it is
very hard to exchange control information between protocol layers.
This document defines nine kinds of L2 abstractions in the form of
"primitives" to achieve fast handovers in the network layer as a means
of solving the problem.  This mechanism is called "L3-driven fast
handovers" because the network layer initiates L2 and L3 handovers by
using the primitives.  This document is a product of the IP Mobility
Optimizations (MobOpts) Research Group.  This memo defines an Experimental 
Protocol for the Internet community.
