Settings for discovery configuration.
<<extension>> This QoS policy controls the amount of delay in discovering entities in the system and the amount of discovery traffic in the network.
The amount of network traffic required by the discovery process can vary widely, based on how your application has chosen to configure the middleware's network addressing (e.g., unicast vs. multicast, multicast TTL, etc.), the size of the system, whether all applications are started at the same time or whether start times are staggered, and other factors. Your application can use this policy to make tradeoffs between discovery completion time and network bandwidth utilization. In addition, you can introduce random back-off periods into the discovery process to decrease the probability of network contention when many applications start simultaneously.
| Duration_t DDS::DiscoveryConfigQosPolicy::participant_liveliness_lease_duration |
The liveliness lease duration for the participant.
This is the same as the expiration time of the DomainParticipant as defined in the RTPS protocol.
If the participant has not refreshed its own liveliness to other participants at least once within this period, it may be considered as stale by other participants in the network.
Should be strictly greater than DDS::DiscoveryConfigQosPolicy::participant_liveliness_assert_period.
[default] 100 seconds
[range] [1 nanosec,1 year], > participant_liveliness_assert_period
| Duration_t DDS::DiscoveryConfigQosPolicy::participant_liveliness_assert_period |
The period to assert liveliness for the participant.
The period at which the participant will refresh its liveliness to all the peers.
Should be strictly less than DDS::DiscoveryConfigQosPolicy::participant_liveliness_lease_duration.
[default] 30 seconds
[range] [1 nanosec,1 year), < participant_liveliness_lease_duration
| RemoteParticipantPurgeKind DDS::DiscoveryConfigQosPolicy::remote_participant_purge_kind |
The participant's behavior for maintaining knowledge of remote participants (and their contained entities) with which discovery communication has been lost.
Most users will not need to change this value from its default, DDS::RemoteParticipantPurgeKind::LIVELINESS_BASED_REMOTE_PARTICIPANT_PURGE. However, DDS::RemoteParticipantPurgeKind::NO_REMOTE_PARTICIPANT_PURGE may be a good choice if the following conditions apply:
[default] DDS::RemoteParticipantPurgeKind::LIVELINESS_BASED_REMOTE_PARTICIPANT_PURGE
| Duration_t DDS::DiscoveryConfigQosPolicy::max_liveliness_loss_detection_period |
The maximum amount of time between when a remote entity stops maintaining its liveliness and when the matched local entity realizes that fact.
Notification of the loss of liveliness of a remote entity may come more quickly that this duration, depending on the liveliness contract between the local and remote entities and the capabilities of the discovery mechanism in use. For example, a DDS::DataReader will learn of the loss of liveliness of a matched DDS::DataWriter within the reader's offered liveliness lease duration.
Shortening this duration will increase the responsiveness of entities to communication failures. However, it will also increase the CPU usage of the application, as the liveliness of remote entities will be examined more frequently.
[default] 60 seconds
[range] [0, 1 year]
| System::Int32 DDS::DiscoveryConfigQosPolicy::initial_participant_announcements |
The number of initial announcements sent when a participant is first enabled or when a remote participant is newly discovered.
Also, when a new remote participant appears, the local participant can announce itself to the peers multiple times controlled by this parameter.
[default] 5
[range] [0,1 million]
| Duration_t DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period |
The minimum period between initial announcements when a participant is first enabled or when a remote participant is newly discovered.
A random delay between this and DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period is introduced in between initial announcements when a new remote participant is discovered.
The setting of DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period must be consistent with DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period. For these two values to be consistent, they must verify that:
DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period <= DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period.
[default] 1 second
[range] [1 nanosec,1 year]
| Duration_t DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period |
The maximum period between initial announcements when a participant is first enabled or when a remote participant is newly discovered.
A random delay between DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period and this is introduced in between initial announcements when a new remote participant is discovered.
The setting of DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period must be consistent with DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period. For these two values to be consistent, they must verify that:
DDS::DiscoveryConfigQosPolicy::min_initial_participant_announcement_period <= DDS::DiscoveryConfigQosPolicy::max_initial_participant_announcement_period.

| Duration_t DDS::DiscoveryConfigQosPolicy::default_domain_announcement_period |
The period to announce a participant to the default domain 0.
The period at which a participant will announce itself to the default domain 0 using the default UDPv4 multicast group address for discovery traffic on that domain.
For domain 0, the default discovery multicast address is 239.255.0.1:7400.
To disable announcement to the default domain, set this period to DDS::Duration_t::DURATION_INFINITE.
When this period is set to a value other than DDS::Duration_t::DURATION_INFINITE and DDS::DiscoveryConfigQosPolicy::ignore_default_domain_announcements is set to false, you can get information about participants running in different domains by creating a participant in domain 0 and implementing the on_data_available callback in the DDS::ParticipantBuiltinTopicData built-in DataReader's listener.
You can learn the domain ID associated with a participant by looking at the field DDS::ParticipantBuiltinTopicData::domain_id.

| Duration_t DDS::DiscoveryConfigQosPolicy::locator_reachability_assert_period |
Period at which this DomainParticipant will assert the locators discovered from other DomainParticipants.
This setting configures the period at which this DDS::DomainParticipant will ping all the locators that it has discovered from other DomainParticipants. This period should be strictly less than DDS::DiscoveryConfigQosPolicy::locator_reachability_lease_duration.
If DDS::DiscoveryConfigQosPolicy::locator_reachability_lease_duration is DDS::Duration_t::DURATION_INFINITE this parameter is ignored. The DomainParticipant will not assert remote locators.
[default] 20 seconds
[range] [1 nanosec,1 year]
| Duration_t DDS::DiscoveryConfigQosPolicy::locator_reachability_lease_duration |
The time period after which other DomainParticipants can consider one of their locators as "unreachable" if they do not receive a REACHABILITY PING from this DomainParticipant.
For the purpose of this explanation, we will use 'local' to refer to the DomainParticipant in which we configure locator_reachability_lease_duration and 'remote' to refer to the other DomainParticipants communicating with the local DomainParticipant.
This setting configures a timeout announced to the remote DomainParticipants. This timeout is used by the remote DomainParticipants as the maximum period by which a remote locator must be asserted by the local DomainParticipant (through a REACHABILITY PING message) before considering this locator as "unreachable" from the local DomainParticipant.
When a remote DomainParticipant detects that one of its locators is not reachable from the local DomainParticipant, it will notify the local DomainParticipant of this event. From that moment on, and until notified otherwise, the local DomainParticipant will not send RTPS messages to remote DomainParticipants using this locator.
If this value is set to DDS::Duration_t::DURATION_INFINITE, the local DomainParticipant will send RTPS messages to a remote DomainParticipant on the locators announced by the remote DomainParticipant, regardless of whether or not the remote DomainParticipant can be reached using these locators.
[default] DDS::Duration_t::DURATION_INFINITE
[range] [1 nanosec,1 year] or DDS::Duration_t::DURATION_INFINITE
| Duration_t DDS::DiscoveryConfigQosPolicy::locator_reachability_change_detection_period |
Period at which this DomainParticipant will check if its locators are reachable from other DomainParticipants.
This setting determines the maximum period at which this DomainParticipant will check to see if its locators are reachable from other DomainParticipants according to the other DomainParticipants' DDS::DiscoveryConfigQosPolicy::locator_reachability_lease_duration value.
If DDS::DiscoveryConfigQosPolicy::locator_reachability_lease_duration is DDS::Duration_t::DURATION_INFINITE this parameter is ignored. The DomainParticipant will not schedule an event to see if its locators are reachable from other DomainParticipants.
[default] 60 seconds

Used to ignore the announcements received by a participant on the default domain 0 corresponding to participants running on domains IDs other than 0.
This setting only applies to participants running on the default domain 0 and using the default port mapping.
When this setting is set to true, a participant running on the default domain 0 will ignore announcements from participants running on different domain IDs.
When this setting is set to false, a participant running on the default domain 0 will provide announcements from participants running on different domain IDs to the application via the DDS::ParticipantBuiltinTopicData built-in DataReader.
