  1. Zero stats OK done Send data frames at regular intervals Inter-packet time ●●● ●●● Time to receive Time to send Get remote statistics Send statistics UDPmon Measuring Throughput with UDP • Send a burst of UDP frames spaced at regular intervals • Vary the frame size and the frame transmit spacing • Record • The time to send and the time to receive the frames • The number received, the number lost, number out of order • The received inter-packet spacing

  2. UDPmon – Status • Tool operational at Manchester • RAL UCL Bologna Lyon NBI CERN SARA • And CERN • MAN RAL Bologna Lyon SARA • Cgi script to generate web .gif display – based on Pinger • Web page rather primitive – will include Antony’s • Cgi script for LDAP access discussed – simple mod! • Cgi script for extraction of data for comparison half discussed!!
