3.5 Ack’ed Mode
UDP is not a 100% reliable connection and occasional reports or command/responses may be
lost. Since all commands have responses, the server can repeat any command to which there is no
response. In order to assure reliable reception of reports, LTE-V devices can be configured either
in Normal or Ack’ed mode to send the reports. In the Normal mode the reports are simply sent “as
is” with no acknowledgment from the server. In the Ack’ed mode every report sent is expected to
be acknowledged by the server by sending back an ACK message back. If
acknowledgement is
not received within the specified timeout, the report is re-sent. If the report is not acknowledged
after the specified number of attempts, it is queued. If acknowledgement is received after the
report is queued (i.e. past timeout
of the last attempt), it is ignored.
Report is not considered “complete” until its acknowledgement is received. Thus, if report X is
sent and report X+1 is triggered while waiting for acknowledgement of X, report X+1 will be
queued until such acknowledgement is received and only then sent. The LTE-V will attempt to
re-send queued report(s) every time a new report is triggered. If there is more than one report
