Make a UDP connection with Python

Write a client

#!/usr/bin/env pythonfrom Socket Import *host = ' 10.2.167.115 ' port = 20001BUFSIZE = 1024ADDR = (HOST, PORT) Udpclientsock = Socket (Af_inet, SOCK_DGRAM) while True:    data = raw_input (' Enter the message want to send > ')    if not data:
   break    udpclientsock.sendto (data, ADDR) is sent to server    data, ADDR = Udpclientsock.recvfrom (BUFSIZE) to receive server-side information    if Not data:        break    print dataudpclientsock.close ()

Write a service-side

#!/usr/bin/env python#-*-coding:utf-8-*-from Socket import *from time Import ctimehost = ' Port = 20001 monitoring Port bufsize = 10 24 Buffer Size ADDR = (HOST, PORT) Udpsersock = socket (af_inet, Sock_dgram) Udpsersock.bind (ADDR) while True:    print ' Waiting For message ... '    data, addr = Udpsersock.recvfrom (BUFSIZE)    udpsersock.sendto (' [%s]%s '% (CTime (), data), addr) Send message to client    print ' received from%s >>%s '% (addr, data) Udpsersock.close ()

This UDP connection can be used for speed measurement. The start and end times are logged on the client. Divide by 2 to estimate the network time-consuming. Ignore server response time
