都是基于Python的：
UDP Server
```
import SocketServer

class MyUDPHandler(SocketServer.BaseRequestHandler):
    """
    This class works similar to the TCP handler class, except that
    self.request consists of a pair of data and client socket, and since
    there is no connection the client address must be given explicitly
    when sending data back via sendto().
    """

def handle(self):
        data = self.request[0].strip()
        socket = self.request[1]
        print "%s wrote:" % self.client_address[0]
        print data
        socket.sendto(data.upper(), self.client_address)

if __name__ == "__main__":
   HOST, PORT = "192.168.1.80", 8090
   server = SocketServer.UDPServer((HOST, PORT), MyUDPHandler)
   server.serve_forever()
```

UDP Client
```
import socket
import sys

HOST, PORT = "192.168.1.30", 8090
data = " ".join(sys.argv[1:])

# SOCK_DGRAM is the socket type to use for UDP sockets
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# As you can see, there is no connect() call; UDP has no connections.
# Instead, data is directly sent to the recipient via sendto().
sock.sendto(data + "
", (HOST, PORT))
received = sock.recv(1024)

print "Sent:     %s" % data
print "Received: %s" % received
```
