After reflecting on Draft 3 that I have now
finished reviewing, it has just occurred to me that as a user of RPR I have seen
absolutely no guidance on how to determine the amount of High Priority (A0 and
A1) traffic I can put on the ring. How can I make use of having both the
inner and outer ringlets available? How can I capitalize on
destination stripping to sell more high priority bandwidth? Until I
know how to answer these questions, I have no good basis for comparing the
efficiency of RPR and SONET, or other technologies. Is the answer buried
somewhere in the text? If not, is there general agreement that we need, if
not additional algorithms to define how to limit A0 and A1 traffic to avoid
overflows, and yet take advantage of the benefits of RPR, then at least
some sort of application note (as an informative annex) that will provide both
guidance and some general numbers that can be used to compare RPR with competing
technologies?
I welcome your comments.
