Hello all,
	just a couple of clarifications on the questions on my talk as they were quite specific.

This was a question on a diagram of an "effect on flooding indication" measurement. One of the two curves (the before-curve) contained only about 35 LSPs and the question was how many LSPs were measured in the other.

This was a proposal from Clarence, I beleive, to tune the process-max-time since it should give smaller maximum flooding delays (among other things).

This was a comment on the convergence measurement we perform since we actually only measure the number of test packets lost. Systematically inspecting the TTL would tell us if we had transient loops. I could do naught but agree but complemented with the information that manual inspection of a number of cases has shown that loops do exist but are very short lived and uncommon.

Cheers,
