Some decisions made
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
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.
