Volker: OK, I will add a clarifying paragraph at the end of S4.2 as
follows:

    The "oc-algo" parameter does not define the exact algorithm to be
    used for traffic reduction, rather, the intent is to use any
    algorithm from a specific class of algorithms that affect traffic
    reduction similarly.  For example, the reference algorithm in
    Section 6.3 can be used as a loss-based algorithm, or it can be
    substituted by any other loss-based algorithm that results in
    equivalent traffic reduction.

OK.

Unless someone has any further feedback on the above text, I will -13
early next week and that version can be moved ahead.

Thank you,
