Now then, Meral,
I think computation times *might* be dependent on CPU power, loading,
compiler efficiency, software implementation, algorithm choice, network
complexity, etc.
Some observations suggest that computation for single LSPs with normal
constraints can be achieved using CSPF and there are studies recording the
number of logical steps needed to perform such a computation. In general,
for this type of computation, we observe that a remote PCEP communication
takes far more time than the computation. (Times may vary according to the
pre-existence of the PCEP session.)
Other observations note that some computation problems are quite hard and
need a few more cycles. In these cases, given the low power of CPUs on NEs,
the communication time may be less significant.
Cheers,
Adrian

Subject: [Pce] PCE computation time
Hi,
Does anyone have actual values for the min/average/max PCE computation
times
in a real network?
I remember that the issue was discussed for the monitoring draft.
Thanks,
Meral
