A UDP link is established between an outgoing UDP initiator (the “slave”) and an incoming UDP listener (the “master”). The core connection parameters configured on the connection itself are Bandwidth and Retransmit Count
What it is: The target packet transmission rate capped in Megabits per second.
Why it matters: UDP has no native hardware-level congestion control. If the sender transmits faster than the receiver's CPU or network interface can process packets, the intermediate Ethernet switches, network cards, or OS kernels will silently drop datagrams. You should restrict the bandwidth to a value lower than the minimum physical bottleneck bandwidth of your connection.
What it is: The number of times the sender re-sends a duplicate of
every outgoing UDP packet (ranges from
0 to 10 extra copies, where
0 means send once, 1 means send
twice, etc.).
Why it matters: Since the receiver cannot request a retransmission over a data diode, the sender pre-emptively sends redundant copies of every packet to overcome transient random packet drops over the wire.
Network Impact: Setting Retransmit Count to 1 (sending 2 copies of
every packet) doubles the bandwidth required for the payload. Ensure your
configured Bandwidth limit can accommodate
this redundant multiplier.
