'''tcptrace''' is a [[Free and open-source software|free and open-source]] tool for analyzing [[Transmission Control Protocol|TCP]] [[dump file]]s.<ref>{{cite book|isbn=978-0471481140|title=Network Performance Open Source Toolkit: Using Netperf, tcptrace, NISTnet, and SSFNet|last1=Blum|first1=Richard|date=2003-08-06|publisher=John Wiley & Sons }}</ref><ref>{{cite journal |last1=Brooks |first1=David E. |last2=Gassman |first2=Holly |last3=Beering |first3=Dave R. |last4=Welch |first4=Arun |last5=Hoder |first5=Douglas J. |last6=Ivancic |first6=William D. |title=High-Speed TCP Testing |date=1999 |url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19990049209.pdf |access-date=11 August 2018}}</ref><ref>{{cite book |last1=Jansen |first1=Sam |last2=McGregor |first2=Anthony |title=2007 Winter Simulation Conference |chapter=Validation of simulated real world TCP stacks |date=2007 |pages=2177–2186 |doi=10.1109/WSC.2007.4419852 |hdl=10289/1725 |isbn=978-1-4244-1305-8 |s2cid=5286358 |chapter-url=https://researchcommons.waikato.ac.nz/bitstream/handle/10289/1725/Validation%20of%20simulated%20real%20world%20TCP%20stacks.pdf?sequence=1&isAllowed=y |access-date=11 August 2018|hdl-access=free }}</ref> It accepts as input files produced by [[Packet sniffer|packet-capture program]]s, including [[tcpdump]], [[Wireshark]], and [[snoop (software)|snoop]].

tcptrace can produce several different types of output containing information on each [[Telecommunication circuit|connection]] seen, such as elapsed time, [[byte]]s and segments sent and received, retransmissions, [[Round-trip delay time|round trip times]], window advertisements, and [[throughput]]. It can also produce [[Computer graphics|graphs]] for further analysis. As of version 5, minimal [[User Datagram Protocol|UDP]] processing has been implemented in addition to the TCP capabilities.
