LOM Calculation for the Russian Dolls Bandwidth Model

The following formulas show how the LOM is calculated for the Russian dolls bandwidth model:



Unreserved TE-Class (i) = LOMc x MIN [ 

[ BCc - SUM ( Normalized (CTb, q) ) ] for q <= p and c <= b <= 7, 
. . . 
[ BC0 - SUM ( Normalized (CTb, q) ) ] for q <= p and 0 <= b <= 7, 

]

where:

LOMc—LOM for class type c.
BCc—Bandwidth constraint for class type c.
TE-Class(i) <– –>(CTc , preemption p ) in the configured TE-Class mapping.

Note that the impact of an LSP on the unreserved bandwidth of a class type does not depend only on the LOM for that class type—it also depends on the LOM for the class type of the LSP.
