well, e'thing can be improved. I found what I suggesed since Les asked works well enough ... As they say, your mileage may vary whatever you suggest as absolute value in MaxLPSTx will not hold up the test of time, 10/sec was a great value in 80s ... --- tony On Tue, Mar 10, 2020 at 3:39 PM

Chris/Acee - I strongly agree with Peter. There is no point in creating a protocol specific registry for behavior values which are protocol agnostic. This only adds duplication (which is NOT the same as redundancy  ). What I find unfortunate is that the table in Section 10 of

With regards to punting to TCP, I think that TCP (stacks) enforce packet ordering. i.e. if you receive packets 1, 3,4, …,N, then you can only use packet 1 until you receive packet 2. In the meantime, you cannot use the (N-2) packets that you did received. That seems like a regression for IS-IS

Hey Christian, MaxTX is not that hard to derive since it's basically limited by the local system and its CPU/prioritization/queing architecture. For the rest of your email, in short, you have my observations in the previous email what I think is useful and can be done ... BTW, timestamps are
