mscAal1CesIdleSuppression
Module: Nortel-MsCarrier-MscPassport-CircuitEmulationServiceMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-CircuitEmulationServiceMIB::mscAal1CesIdleSuppression
OID (numeric): 1.3.6.1.4.1.562.36.2.1.119.11.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute controls the suppression of idle cells. An idle cell is one in which the bytes of the ATM payload (up to the partialFill level) match the idlePattern.
If idleSuppression is off, idle cells are not suppressed.
If idleSuppression is on, at least 75% of cells are suppressed under idle conditions.
The strategy is as follows: the first idle cell after a sequence of non- idle cells is always sent; those that follow are suppressed. Note, however, that at least one cell in eight is always sent (to allow the receive end to regenerate the suppressed cells) and more often than not, two cells are sent (the cell containing the AAL1 pointer, which will almost always fail to match, and the one after that).
What is mscAal1CesIdleSuppression?
Turns on/off suppression of cells whose payload matches the configured idle pattern; when on, at least 75% of otherwise-redundant idle cells are not sent, saving ATM bandwidth during quiet periods while the far end can still regenerate them.
