UDP, TCP, and IP Fragmentation Analysis and Its Importance in TOE Devices

In this document three different networks environments are analyzed using a TCP/IP offload engine point of view. Internet related protocols are studied in a real environment in order to assign candidates for a real TCP/IP offload engine implementation. The number of broadcast and unicast packets received are also analyzed. The test setup, network configurations, and the analysis of results are presented. A formula for calculating the number of wasted interrupts is presented. Also, tasks priorities imperative to implement in a TCP/IP offload device are established. This analysis improves the framework discussed on (Solá-Sloan02).
