next_retry

struct GNUNET_TIME_Absolute CadetReliableMessage::next_retry

How soon should we retry if we fail to get an ACK? Messages in the queue are sorted by this value.

Definition at line 144 of file gnunet-service-cadet_channel.c.

Referenced by cmp_crm_by_next_retry(), and data_sent_cb().

retry_delay

struct GNUNET_TIME_Relative CadetReliableMessage::retry_delay

How long do we wait for an ACK after transmission? Use for the back-off calculation.

Definition at line 150 of file gnunet-service-cadet_channel.c.

Referenced by data_sent_cb().

first_transmission_time

struct GNUNET_TIME_Absolute CadetReliableMessage::first_transmission_time

Time when we first successfully transmitted the message (that is, set num_transmissions to 1).

Definition at line 156 of file gnunet-service-cadet_channel.c.

Referenced by data_sent_cb(), and handle_matching_ack().

connection_taken

struct GNUNET_CADET_ConnectionTunnelIdentifier CadetReliableMessage::connection_taken

Identifier of the connection that this message took when it was first transmitted.

Only useful if num_transmissions is 1.

Definition at line 162 of file gnunet-service-cadet_channel.c.

Referenced by data_sent_cb(), and handle_matching_ack().

num_transmissions

int CadetReliableMessage::num_transmissions

How often was this message transmitted? GNUNET_SYSERR if there was an error transmitting the message, GNUNET_NO if it was not yet transmitted ever, otherwise the number of (re) transmissions.
