aal2CpsPerfCongestion
Module: ZhoneAAL2-MIB
OID (symbolic): ZhoneAAL2-MIB::aal2CpsPerfCongestion
OID (numeric): 1.3.6.1.4.1.5504.4.2.1.5.1.11
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The congestion happens when the aal2 receiver is ready to receive cells but there is no buffer ready. The receiver starts dropping cells. The receiver tries to open new buffers for cell reception only after the last cell of the discarded frame arrives.
This variable represents the number of times the receiver verified the receive queue for cell reception but the queue was busy. This is called congestion event.
What is aal2CpsPerfCongestion?
Counts congestion events, where the receiver checked its receive queue for an incoming cell but found no buffer available and had to drop cells until the next frame boundary; a growing count signals the device is running short of receive buffers under load.
