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
