llcCcOperWw
Module: A3COM-LIC-R1-MIB
OID (symbolic): A3COM-LIC-R1-MIB::llcCcOperWw
OID (numeric): 1.3.6.1.4.1.43.2.26.3.2.1.15
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Maximum number of sequentially numbered IPDUs that the connection component may have outstanding (unacknowledged) at any given time. Ww is initialized to the value of llcCcOperMaxUnackedIPDUsSend when the link is established. When the dynamic window algorithm is invoked, Ww varies from 1 up to llcCcOperMaxUnackedIPDUsSend.
Each time the llcCcOperWw value is decreased, the reason is recorded in llcCcOperLastWwCause, and llcCcStatWwCount is incremented by 1.
This function is not described in the IEEE 802.2 specification [5], but is widely implemented.
What is llcCcOperWw?
This OID reports the current working window size (1-127), limiting concurrent unacknowledged I-frames. It starts at maximum but shrinks during congestion, then gradually recovers. A typical value of 32 means the device can have 32 frames in flight before waiting for acknowledgments.
