Discrete |
Current
size of application read queue |
- |
read-only |
Gauge32 |
4app |
standard |
- |
The
current number of octets of application data that has beenacknowledged by TCP
but not yet delivered to the application. |

2^32-1 |
Supported |
Discrete |
Current
size of application write queue |
- |
read-only |
Gauge32 |
4app |
standard |
- |
The
current number of octets of application databuffered by TCP, pending first
transmission. i.e. to the left of SND.NXT or SndMax. This data will generally
be transmitted (and SND.NXT advanced to the left) as soon as there is
available congestion window (cwnd) or receiver window (rwin). This is the
amount of data readily available for transmission, without scheduling the
application. TCP performance may suffer if there is insufficient queued write
data. |
