Technical Summary:

This document contains a brief overview of difficulties cause by
multi-destination local network traffic, such as unicast frames
where the location of the destination is unknown or ARP/ND packets,
and a generic description of how to reduce such difficulties
through the use of push and/or pull directories. Data Centers are
frequently orchestrated by management software that maintains a
directory of the applications, Virtual Machines, IP and MAC
addresses in use and the switches to which they are attached. This
makes directory assistance to edge switches a reasonable strategy
for that case.
