[Nsi-wg] action items from call today

[Radek Krzywania]

Hi all,
In the attachment you will find PF examples. I've used term PCE as Path
Computation Element, which is standardized somewhere, but naming is open.
It's not full list of cases, as there may be many permutations, but I guess
it may give an overview. The main issue is that the path provided by PCE in
the first domain, MAY or MAY NOT include details if each domain along
reservation path. Thus reservation process MAY include some negotiations
elements, where each domain will do local path finding and provide a
detailed path (or will just calculate it, and keep hidden against other
domains).
If a requested connection does not start in the user home domain (where
request was submitted), two scenarios are possible:
- domain will be responsible to manage the reservation, thus it will not do
local domain path computation, only the global one to define reservation
source domain.
- domain will delegate this responsibility to first domain on reservation
source path (may be more complicated in fact)

Best regards
Radek
