Abstract
Introduction We designed and implemented a software for packet capture and analysis and to extract samples of what we identified as random variables. We called it PLAB. We tried to design a program flexible enough but that needed as few processing resources as possible, to be capable of analyzing tra#c traces of hundreds of millions packets. In this chapter we illustrate the main architecture of the software, motivate some design decisions and describe some features that were introduced. 2 Libpcap As regards packet capture, PLAB is based on the Libpcap library[JLM], which is an open source C library o#ering an interface for capturing link-layer frames over a wide range of system architectures. It provides a high-level common Application Programming Interface to the di#erent packet capture frameworks of various operating systems. The o#ered abstraction layer allows programmers to rapidly develop highly portable applications. Moreover it defines a common standard format for files in w
