#
# model description of the tables used to configure and
# view the controller state.
#
# these tables are used both by sdnplatform and the rest api.
# the cli uses the rest api to read and write these tables,
# while sdnplatform/sdnplatform has a more direct interface to the
# tables.
#
# for the cli, the names of the fields are described in the
# 'class Rest' section of each of the tables.
#
# for sdnplatform the names of fields have a relationship to their
# type for sdnplatform. If a field is a foreign key, then an '_id'
# is appended to the name for the same field within sdnplatform. This
# means if a field is promoted or demoted to/from a foreign key,
# changes need to be made in the sdnplatform code to use the updated
# name.
#
# Make sure to include the nested Rest class or else they won't be
# accessible using the REST API.

# Note: This model should only contain config state for the controller VM,
# not any operational state.
#
# Note: The convention used to be that the controller ID was
# the IP address and port that the OpenFlow controller was listening
# on. In practice SDNPlatform listened on all interfaces and it's logic
# for determining its real IP address was unreliable, so it was
# changed/simplified to just always use "localhost" for the
# IP address. So the controller ID was pretty much always
# "localhost:6633". The use of "controller here caused some
# confusion about whether "controller" meant the
# OpenFlow controller (i.e. SDNPlatform/SDNPlatform) vs. the controller VM.
# In the old controller model most/all of the settings concerned the
# OpenFlow controller not the VM>
# Most of the settings we now want to associate with the controller are
# controller VM settings (e.g. IP address, DNS, time zone) and not
# OpenFlow controller settings. So we're repurposing the Controller
# model to be the controller VM config state and not the OpenFlow
# controller discovered state (which was sort of broken to begin with).
# Currently (as of 10/2011), since we only support single node operation
# the controller ID is hard-coded to be localhost (probably should be
# something different, e.g. "default", because localhost implies a
# an interface which is really something separate), but eventually for
# multi-node operation we'll need to have unique ids for each controller
# node in the cluster. The easiest way would be to have the user enter
# something at first time config. Or possibly we could do something
# with GUIDs. Needs more thought...
