Multi-media messages are typically very large and vary from tens to thousands of kilobytcs in size.This paper investigates the transmission of large multi-media messages on an Ethernet LAN, Internet WAN, and an ATM LAN.We proposed a UDP cooling method by introducing a.short delay between each datagram for large message transmissions.Experiments show that the round-trip UDP datagram loss rate can be reduced from 85% to 8% with a slight performance downgrade for messages larger than 200 Kbytes on the Ethernet LAN.We also conducted experiments by applying UDP cooling method to WAN and an ATM LAN.Experiments with regular UDP and TCP transmission were conducted for comparison of performance and reliability.On the basis of these experiment results, we provided guidelines about using TCP, UDP, and UDP cooling for multimedia data transmission.
