This paper describes a new tool being made available to the networking research community for passive analysis of TCP segment traces. The purpose of the tool is to provide more complete and accurate classification of out-of-sequence segments than those provided by prior tools. One of the crucial factors that limit the accuracy of prior tools is that these do not incorporate variations across TCP implementations (for different operating systems) that have different parameters (e.g., timer granularity, minimum RTO, duplicate ACK thresholds, etc.) or algorithms that influence what can be inferred about out-of-sequence segments. The tool explicitly accounts for implementation-specific details in four prominent TCP stacks (Windows, Linux, FreeBSD/Mac OS-X, and Solaris).
