Hi Adrian and Dan,
I have the following comments on this draft. I was
wondering what were the objectives for the IGP evaluation. IMHO the evaluation
from WSON perspective should address the following:
1. IGP usage in the context of traditional
distributed solutions for WSON
[Dan] With the situation that TE information is
already be carried by IGP, it's nature to think that the wavelength
information can also be carried by IGP. I am not saying it should be, but it's
worth to look at.
2. IGP usage in the context of PCE solutions
[Dan] It's a potential way for PCE to
get the wavelength information.
3. Flooding and refresh of static and
dynamic link state updates
[Dan] Try to figure out the impact to the
performance of IGP.
4. Data base sync-up during node
[Dan] Yes, this should be
considered. Especially the very large amount of data
will be sent to the restarting node. We may consider the point to point data
exchange instead of flooding the LSA updates. Or slice the big data packet
into small pieces.
Could you please let me know if the above is within
the current scope? I believe that these are important.
