Dear Authors, I've read the new draft and have some questions that I would like us to discuss:
- which of BFD modes, Async, Demand or Echo, you envision to be used by this new TLV; - what interval between the BFD control packets with BFD Performance TLV would you use; - the BFD Performance TLV has space for four timestamps. Should that suggest that only Echo mode will be used to measure delay? Because if you use Asunc or Demand, then I don't see the need for four timestamp as two will be sufficient. In these modes you can only perform one-way measurement (of course, one can envision implementation that will read timestamp from the remote peer and copy them into the outgoing control packet). Thus, how useful to have measurement result at the far end when it is the sender that is interested in it? Why not to use one of existing PM OAM tools, TWAMP, TWAMP Light or STAMP? Regards, Greg
