Previous discussion indicated that link definition of RFC 4861 "Neighbor
Discovery for IPv6" is pertinent to 6LoWPAN. I agree with it and
suggest the following 6LoWPAN definition:
link - a communication facility or medium over which
nodes can communicate at the link layer, i.e.,
the layer immediately below IP (each node can
communicate to each other in this medium).
Examples are Ethernets (simple or bridged), PPP
links, X.25, Frame Relay, wireless links or ATM
networks as well as Internet-layer (or
higher-layer) "tunnels", such as tunnels over
IPv4 or IPv6 itself.
This is a slightly modified definition of the link
defined in RFC4861, in order to cover also the wireless
links. Wireless links may be non-transitive (node A
communicates at link layer to both B and C yet B and C
are not on the same link). Hidden terminal problem in
wireless communications is described in [reference to
individual draft in AUTOCONF]
draft-baccelli-multi-hop-wireless-communication-02
What do people think about using this link definition in 6LoWPAN?
