question related to DS-TE-PROTO: Does advertised unreserved bw take LOM into account ?
Hi! Here is a question related to DS-TE-PROTO-3 draft.
Is the following assumption correct ?
The per-TE-Class unreserved bandwidth advertised by IGPs, are
the actual bandwidth available for the TE-Class [i.e _without_ taking
the LOM into account.]
The PCM of the a LSR may use the advertised unreserved BW and
value from the LOM TLV, to decide (/predict), whether it should use
a specific link.
A simplistic example:
(i) Assume the actual link bw 100M
(ii) Only CT0 is supported (and only 1 preemption priority
supported)
(iii) LOM[0] = 200%
Case-1: No LSPs have been established
Assumption:
-------------
In this case the Adv bw is 100M (and not 200M)
[Although 200M worth of CT0 connections can be
established]
Case-2: 1 LSP with 50M bandwidth has been established
Assumption:
--------------
In this case the Adv bw is = 100 -50/2 = 75M (and not 200
-50 = 150M)
Thanks,
