Kireeti,
You are correct that any change would be minimally disruptive. In the
example I gave there could be no more than one change in 20 minutes,
but still more than zero.
I personally don't think a warning is needed here, but if you and/or
others feel it is needed I have no objections to adding it. The text
would then be:
[FR#N] Load balancing MAY be used during sustained low traffic
periods to reduce the number of active component links for
the purpose of power reduction.
As with any load balancing change, a change initiated for the
purpose of power reduction may be minimally disruptive. Typically
the disruption is limited to a change in delay characteristics and
the potential for a very brief period with traffic reordering. The
network operator when configuring a network for power reduction
should weight the benefit of power reduction against the
disadvantage of a minimal disruption.
The first paragraph is a requirement. The second paragraph is
discussion and should not appear within a numbered list of
requirements.
I would like comments from you and others. Do we need to add this
requirement? If so do we need to add this warning?
Curtis
