Class Type Bandwidth and the LOM


The following formula expresses the relationship between the bandwidth of the class type and the LOM. The normalized bandwidth of the class type (NB) is equal to the reserved bandwidth of the class type (RB) divided by the LOM of the class type (LC):

When calculating available bandwidth, you need to subtract the normalized bandwidth from the relevant bandwidth constraint.


When using an LOM, values advertised for the available bandwidth might be larger than the bandwidth constraint values. However, the values advertised in the maximum link bandwidth advertisement are not affected by local oversubscription.
