atmIfVpcTmAbrRateDecreaseFactor
Module: Nortel-Magellan-Passport-AtmCoreMIB
OID (symbolic): Nortel-Magellan-Passport-AtmCoreMIB::atmIfVpcTmAbrRateDecreaseFactor
OID (numeric): 1.3.6.1.4.1.562.2.4.1.114.4.9.2.110.1.13
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This attribute is applicable and is displayed only for connections for which the operational Tm abrConnectionType is displayed as sourceDest or virtualSourceDest.
This attribute indicates the Rate Decrease Factor (RDF) for this connection. The RDF value is computed by using the operational value of this attribute, n, as 2 to the inverse power n. For example, if the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may decrease upon receipt of a backward Resource Management (RM) cell. For example, if a backward RM cell is received with the Congestion Indication (CI) field set to 1, the Allowed Cell Rate (ACR) value would be reduced by the amount (RDF*ACR). The ACR is not allowed to fall below the Minimum Cell Rate (MCR), in which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the provisioned value of the rateDecreaseFactor attribute. For signalled connections, it is indicated in the ABR Setup Parameters Information Element.
