Abstract:
IPv6 Neighbor Discovery (RFC 4861 going back to RFC 1970) was defined
at a time when link-local multicast was as reliable and with the same
network cost (send a packet on a yellow-coax Ethernet) as unicast and
where the hosts were assumed to be always on and connected.
Since 1996 we've seen a significant change with both an introduction
of wireless networks and battery operated devices, which poses
significant challenges for the old assumptions. We are also seeing
datacenter networks where virtual machines are not always on and
connected, and scaling of multicast can be challenging.
This specification contains extensions to IPv6 Neighbor Discovery
which remove most use of multicast and make sleeping hosts more
efficient. The specification includes a default mixed mode where a
link can have an arbitrary mix of hosts and/or routers - some
implementing legacy Neighbor Discovery and some implementing the
optimizations in this specification. The optimizations provide
incremental benefits to hosts as soon as the first updated routers
are deployed on a link.
