Project 1.2: Note about UdpBasicApp application
9 janeiro 2025, 18:12 • António Manuel Raminhos Cordeiro Grilo
In the scenario, the SCADA at DCC "may issue set-points and measurements to all SS, at an average rate of 0.5s each,
with message size 120 bytes."
As already exemplified in the provided omnetpp.ini, the SCADA application (instance of UdpBasicApp) can have more than one destination configured:
**.DCC.app[0].destAddresses = "SS1 SS2"
In this case, the DCC is configured to send messages towards SS1 and SS2.
When UdpBasicApp has more than one destination address configured, it selects the destination randomly for each packet. Since you only have to guarantee "an average rate of 0.5s" (i.e., one message each 0.5s on the average, not necessarily sent in round robin fashion) to each substation, this means that the **.DCC.app[0].sendInterval parameter will correspond to the total message rate for the ensemble of substations (4 substations in total).
