PCAP Analyzer is a tool that helps analyzing network traffic captured in a PCAP format (standard of tcpdump). It has extensible Filters in charge of dissecting packets and printing information like throughput or anything that can be analyzed by Filters (e.g. packet loss, reordering, ...). It comes with several built-in Filters but can be expanded by adding custom-made Filters to the classpath.

It was developped to help understanding complex network routing problems, where packets could arrive out-of-order, some were lost, or duplicated. Network analysis needed to synchronize capture on a local (destination) and remote (source) computers and display warning messages while recording traffic in PCAP format for offline analysis.

PCAPAnalyzer is typically used piped to tcpdump to show warnings on console, with the possibility to replay traffic later, with different Filters.
