2.3. Host Network Quality of Service

Host network quality of service configures the networks on a host to enable the control of network traffic through the physical interfaces. Host network quality of service allows for the fine tuning of network performance by controlling the consumption of network resources on the same physical network interface controller. This helps to prevent situations where one network causes other networks attached to the same physical network interface controller to no longer function due to heavy traffic. By configuring host network quality of service, these networks can now function on the same physical network interface controller without congestion issues.

Create a host network quality of service entry.

Procedure 2.5. Creating a Host Network Quality of Service Entry

  1. Click the Data Centers resource tab and select a data center.
  2. Click QoS in the details pane.
  3. Click Host Network.
  4. Click New.
  5. Enter a name for the quality of service entry in the QoS Name field.
  6. Enter a description for the quality of service entry in the Description field.
  7. Enter the desired values for Weighted Share, Rate Limit [Mbps], and Committed Rate [Mbps].
  8. Click OK.
Host network quality of service settings allow you to configure bandwidth limits for outbound traffic.

Table 2.2. Host Network QoS Settings
Field Name
Description
Data Center
The data center to which the host network QoS policy is to be added. This field is configured automatically according to the selected data center.
QoS Name
A name to represent the host network QoS policy within the Manager.
Description
A description of the host network QoS policy.
Outbound
The settings to be applied to outbound traffic.
  • Weighted Share: Signifies how much of the logical link's capacity a specific network should be allocated, relative to the other networks attached to the same logical link. The exact share depends on the sum of shares of all networks on that link. By default this is a number in the range 1-100.
  • Rate Limit [Mbps]: The maximum bandwidth to be used by a network.
  • Committed Rate [Mbps]: The minimum bandwidth required by a network. The Committed Rate requested is not guaranteed and will vary depending on the network infrastructure and the Committed Rate requested by other networks on the same logical link.

2.3.3. Removing a Host Network Quality of Service Entry

Remove an existing network quality of service entry.

Procedure 2.6. Removing a Host Network Quality of Service Entry

  1. Click the Data Centers resource tab and select a data center.
  2. Click the QoS tab in the details pane.
  3. Click Host Network.
  4. Select the network quality of service entry to remove.
  5. Click Remove.
  6. Click OK when prompted.
