Hi WG,
I have a little doubt about the scheme described in this document.
See the following example:
S ---- X1 ----- X2 ---- ... ... ----- X10 ----- D
\----------------------------------------------/
Suppose the links in S---X1---X2...---D have the same bandwidth 10G, and the
link S-D has bandwidth 1G.
Suppose that we select "reference bandwidth = 100G", then,
each link in S---X1---X2...---D will have the same bandwidth-metric 10 (i.e.,
100/10)
link S-D will have a bandwidth-metric 100 (i.e., 100/100)
So flex-algo path from S to D based on bandwidth-metric will be S-D, not
S---X1---X2...---D, because the later has a large cumulative bandwitdh-metric
(i.e., 11*10).
But our expect path should be S-D, not S---X1---X2...---D, as it has large
bandwidth.
Do I misunderstand anything ?
Regards,
PSF
