The multicast address for Delay Models could be specified as a part

specified for each station).
If we can agree that there is no need to send Delay Models via
MCCC, we should implement things that way from the beginning.

EVLA M&C System (Observation Preparation and/or Executor) knows
which antenna is connected to which Station Board. EVLA M&C System
also knows (and tells MCCC) which Baseband is processed on which
Station Board. Getting IP address for the known Module Location ID
(rack-crate-slot) should be a trivial task (during the testing user may
need to specify IP address manually). Delay Models for a single
Baseband Pair (or for a single Baseband) could be sent to the Station
Board that processes the Baseband (as was initially planned). If the
fragmenting still affects performance, we may abandon XML and send
models in binary format.<br>
