Hello Les,

There is something to be said for simply “flooding fast” and not
worrying about flow control at all (regardless of whether TX or RX
mechanisms would be used). Some packets would be dropped, but
retransmission timers will insure that the flooding eventually
succeeds and retransmit timers are long (5 seconds by default). (I am
not the only one mentioning this BTW…)
Why do we have initial waits and exponential backoffs for LSP-generation
and SPF-computations ? Why not react immediately ? Why not react
constantly ?
We have a lot of bandwidth and cpu-power now. Isn't simple always better
than "overly complex stuff" like exponential backoffs ? If you have more
cpu-power, more memory and more bandwidth, why invent new algorithms ?
henk.
I hope it is clear to everyone that these are not serious questions. I'm
just
saying: "sometimes fast is slow". I am sure that if we ask the "old
guys", they
can come up with many stories how these problems are sometimes
counter-intuitive.
And how networks have melted because "fast is slow". I could tell at
least 2
of those stories myself.
