neutron_lib.services.qos.base module

class neutron_lib.services.qos.base.DriverBase(*args, **kwargs)

Bases: object

create_policy(context, policy)

Create policy invocation.

This method can be implemented by the specific driver subclass to update the backend where necessary with the specific policy information.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being created, which will have no rules.

create_policy_precommit(context, policy)

Create policy precommit.

This method can be implemented by the specific driver subclass to handle the precommit event of a policy that is being created.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being created, which will have no rules.

delete_policy(context, policy)

Delete policy invocation.

This method can be implemented by the specific driver subclass to delete the backend policy where necessary.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being deleted

delete_policy_precommit(context, policy)

Delete policy precommit.

This method can be implemented by the specific driver subclass to handle delete precommit event of a policy that is being deleted.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being deleted

is_loaded()

True if the driver is active for the Neutron Server.

Implement this property to determine if your driver is actively configured for this Neutron Server deployment.

is_rule_supported(rule)
is_vif_type_compatible(vif_type)

True if the driver is compatible with the VIF type.

is_vnic_compatible(vnic_type)

True if the driver is compatible with the specific VNIC type.

update_policy(context, policy)

Update policy invocation.

This method can be implemented by the specific driver subclass to update the backend where necessary.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being updated.

update_policy_precommit(context, policy)

Update policy precommit.

This method can be implemented by the specific driver subclass to handle update precommit event of a policy that is being updated.

Parameters:

  • context – current running context information

  • policy – a QoSPolicy object being updated.

validate_rule_for_network(context, rule, network_id)

Return True/False for valid/invalid.

This is only meant to be used when a rule is compatible with some networks but not with others (depending on network properties).

Returns True by default for backwards compatibility.

validate_rule_for_port(context, rule, port)

Return True/False for valid/invalid.

This is only meant to be used when a rule is compatible with some ports/networks but not with others (depending on port/network properties).

Returns True by default for backwards compatibility.
