This attribute specifies the fairness policy which is applied to
available bandwidth when performing the ER calculation in the
ABR service category. This applies to any connection point
performing explicit rate calculations. Each ABR connection is
assigned a weight. Connections with a higher weight get a greater
proportion of the available ABR bandwidth compared with
connections that have lower weights. This attribute is ignored on
CQC-based ATM cards.
If the value is mcr, the congestion fairness weight is based on the
Minimum Cell Rate (MCR) of the connection.
If the value is pcr, the congestion fairness weight is based on the
Peak Cell Rate (PCR) of the connection.
If the value is pcrMinusMcr, the congestion fairness weight is
based on the difference between the Peak Cell Rate and the
Minimum Cell Rate (PCR - MCR) of the connection.
