UDP Nodes (G Dataflow)

Closes a UDP socket and frees system resources.

Opens a UDP multicast socket to send a single datagram to multiple receivers in parallel on the port you specify. UDP multicasting may have less overhead in code and on the network than unicasting because multicasting does not require the sender to maintain a list of clients or send multiple copies of the data to each client.

Opens a UDP socket to send a datagram to a single receiver on the port or service name you specify. If you want to send a single datagram to multiple receivers in parallel, which may reduce overhead both in code and on the network over sending a datagram to multiple receivers serially, use the UDP Multicast Open node instead of this one.

Reads a datagram from a UDP socket.

Writes a datagram to a remote UDP port. To send multicast datagrams, specify the multicast group address in the address input.
