UDPmon Measuring Throughput with UDP

UDPmon Tool records inter-packet time, time to send/receive data frames, and more to analyze network statistics. Easily measure throughput by sending UDP frames at regular intervals. Monitor data flow with UDP.

Presentation Transcript

  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!!
