Field Documentation

struct DDS_Duration_t DPSE_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 DPSE_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 DPSE_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 DPSE_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_Long DPSE_DiscoveryPluginProperty::max_participant_locators

The maximum number of locators 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 DPSE_DiscoveryPluginProperty::max_locators_per_discovered_participant

The maximum number of locators 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;
