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, ]
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.
