![]() UDPServerSocket.bind((localIP, localPort))īytesAddressPair = UDPServerSocket.recvfrom(bufferSize)ĬlientMsg = "Message from Client:". ![]() UDPServerSocket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM) Since UDP is connectionless protocol the overhead involved in UDP is less compared to a connection based protocol like TCP.An UDP client can send "n" number of distinct packets to an UDP server and it could also receive "n" number of distinct packets as replies from the UDP server.There is no streaming of data between a UDP server or and an UDP Client. The underlying mechanisms that implement UDP involve no connection-based communication.Since there is no guarantee of assured delivery of messages, UDP is considered an unreliable protocol.If for some issue in a network if a packet is lost it could be lost forever. Professional license server is limited to 10 TCP connections and that one way to overcome this is to specify FLEXLMCOMMTRANSPORTUDP to use UDP instead of TCP for the transport protocol. The UDP does not provide guaranteed delivery of message packets. ![]() In communications using UDP, a client program sends a message packet to a destination server wherein the destination server also runs on UDP. UDP makes use of Internet Protocol of the TCP/IP suit. UDP is the abbreviation of User Datagram Protocol. ![]()
