摘要

This paper presents a file sharing traffic analysis methodology for Server Message Block (SMB), a common protocol in the corporate environment. The design is focused on improving the traffic analysis rate that can be obtained per CPU core in the analysis machine. SMB is most commonly transported over Transmission Control Protocol (TCP) and therefore its analysis requires TCP stream reconstruction. We evaluate a traffic analysis design which does not require stream reconstruction. We compare the results obtained to a reference full reconstruction analysis, both in accuracy of the measurements and maximum rate per CPU core. We achieve an increment of 30% in the traffic processing rate, at the expense of a small loss in accuracy computing the probability distribution function for the protocol response times.
