Protocol-, Operating System- and ATM Layer-Limitations in Practical Performance of UDP/IP and TCP/IP over ATM
André Zehl, Thomas P. Kusch · 1995
This paper presents practical performance measurements with IP in a local area ATM network. A general experience running TCP/IP and UDP/IP traffic in a typical ATM LAN environment is an astonishingly poor performance. This paper shows some of the limitations we found out in analysing the reasons for the performance shortcomings. We mainly focus on operating system-, protocol- and ATM layer-limitations. One of the key results of our work is, that the main reason for performance problems, besides the lack of QoS support in IP protocols, are current IP protocol’s implementations.
