Hello all, just a couple of clarifications on the questions on my talk as they were quite specific.
* Operator Experience from IS-IS Convergence Tuning (Henrik Villfoer)
This study is done on the TeliaSonera network. Motivation for such a study is to get a fast convergence time, around 1 sec, for time sensitive new IP services and find the limits of the protocol, IS-IS. Mostly Cisco products are used.
Questions:
"How many LSP do they have?" More than a hundred.
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.
"Suggestion tune the closes-max-time."
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).
"It would be more interesting if there would be more info about flooding loops."
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, Henrik.
