<<eXtension>> Properties for the Dynamic Participant/Dynamic Endpoint (DPDE) discovery plugin. This includes all discovery timing properties for participant discovery.
struct DDS_Duration_t DPDE_DiscoveryPluginProperty::participant_liveliness_assert_period |
The period to assert liveliness for the participant.
Specifies how often the DomainParticipant's discovery DataWriter will assert the liveliness of the DomainParticipant to its peers. Should be strictly less than participant_liveliness_lease_duration. [default] 30 seconds [range] [1 nanosec, 1 year], < participant_liveliness_lease_duration
struct DDS_Duration_t DPDE_DiscoveryPluginProperty::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 participant_liveliness_assert_period. [default] 100 seconds [range] [1 nanosec, 1 year], > participant_liveliness_assert_period
DDS_Long DPDE_DiscoveryPluginProperty::initial_participant_announcements |
The number of initial announcements sent when a participant is first enabled or when a remote participant is newly discovered.
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 will announce itself to the peers a number of times controlled by this parameter. [default] 5
struct DDS_Duration_t DPDE_DiscoveryPluginProperty::initial_participant_announcement_period |
The period between initial announcements when a participant is first enabled or when a remote participant is newly discovered.
[default] 1 second
DDS_Boolean DPDE_DiscoveryPluginProperty::cache_serialized_samples |
Cache serialized discovery samples for locally created data readers and data writers.
When a data reader or data writer is enabled locally, the discovery plugin announces this to other participants in its domain. When this value is set to DDS_BOOLEAN_TRUE the serialized sample is stored in case a new particpant is discovered and the information must be sent again. This may improve discovery performance, but increases memory usage. The default value is DDS_BOOLEAN_FALSE which uses less memory. [default] DDS_BOOLEAN_FALSE;
DDS_Long DPDE_DiscoveryPluginProperty::max_participant_locators |
The maximum number of locators the RTI Connext DDS Micro can send to to discover other participants in the same domain.
The discovery plugin sends participant annoucements to a number of locators as specified in the initial peer list. The maximum number of locators to send too is specified here. The value DDS_LENGTH_AUTO calculates the maximum number of locators as DomainParticipantQos.resource_limits.remote_participant_allocation + (DPDE_MAX_ANON_PARTICIPANT * (initial_peers length + 1)) [default] DDS_LENGTH_AUTO;
DDS_Long DPDE_DiscoveryPluginProperty::max_locators_per_discovered_participant |
The maximum number of locators the RTI Connext DDS Micro can keep track of per discovered participant.
When a participant discover another participant, it must keep track of which addresses to respond to for each participant. NOTE: If two participants respond with the same addresses, for example multicast, only one address is saved. [default] 4;
DDS_Long DPDE_DiscoveryPluginProperty::max_samples_per_builtin_endpoint_reader |
The maximum number of samples allocated per builtin endpoint datareader.
The builtin endpoint datareaders are realiable and may cache samples received out-of-order to improve discovery performance. This resource-limit determines the maximum number of outstanding samples at any given time. [default] 8 [range] [1, 100000000];
