NTAR

NTAR (Network Trace Archival and Retrieval library) is an application provides you the way to transfer network traces with storage device. The NTAR file format includes support for saving a number of per-capture and per-packet details ("metadata"). NTAR implements a new "wanna-be" dump standard that overcomes the limits of the current libpcap/WinPcap dump format, by allowing the user to save packets coming from multiple interfaces and different data-links in a single trace file.
