The Transmit queue length parameter that controls the size of the transmission queue (in packets) for a network interface.
This queue temporarily holds packets in memory before they are sent out through the interface.Available on Artica v4.50 Service Pack1 or Artica v4.50 Hotfix 20241123-00
It specifies the maximum number of packets that can be queued for transmission on a network interface.
It helps manage traffic flow when there is a high rate of outgoing packets, preventing packet loss or delays due to congestion.
- When the interface is busy transmitting packets, new packets are temporarily stored in the transmit queue.
- If the queue is full, additional packets will be dropped, leading to potential packet loss.
The default value depends on the network interface driver, but it is typically:
- 1000 packets for most Ethernet interfaces.
- Smaller values for wireless interfaces (e.g., Wi-Fi).
- In the left meu on “
Network & Nics > Interfaces”, select your Interface. - Down to the “
Transmit Queue length” field ( which is on default to 1000 )
- For high-speed interfaces (e.g., 10Gbps or higher):
- A larger
Transmit Queue length(e.g., 5000–10000) may be appropriate to handle bursts of traffic.
- A larger
- For low-latency networks (e.g., real-time applications or VoIP):
- A smaller
Transmit Queue lengthcan reduce queuing delays.
- A smaller
¶ Example Scenarios
Scenario 1: Large Transmit Queue length
- Interface: 10Gbps Ethernet.
- Traffic: High-volume file transfers.
Transmit Queue length: Set to10000to avoid packet loss during traffic bursts.
Scenario 2: Small Transmit Queue length
- Interface: Gigabit Ethernet.
- Traffic: Real-time video streaming.
Transmit Queue length: Set to100to minimize queuing delays.
