Some decisions made
 PAR and Five Criteria are set (modulo a new Internet
draft).
 We will use Stephen Haddock’s baggy pants model.
 DRNI connects only two networks.
 We have a large set of desired characteristics, among
which are:
• Fast convergence after a failure.
• Capability for bi-directional symmetry of link usage.
• Capability for frame distribution by service.
• Insulation of each connected network from fault events in the
other network.
• No restrictions on the operations of the connected networks.

Some decisions to make
 Do we signal individual services’ states/needs between
Portals, or depend on pre-configured service sets?
• Pro individual: Closer to current practice, easier to describe,
easier to create configuration.
• Con individual: Requires increase in LACP PDU size, and even
then one can run out of space if too many services present.
 What information must be passed among the nodes in
the Interconnect?
• This depends on whether we want to achieve total insulation of
the two networks from each other.
• It depends on whether we want to achieve good load
distribution in the face of networks changing service to Portal
node assignments.
