Public Review for pcapIndex: An Index for Network Packet Traces with Legacy Compatibility Francesco Fusco, Xenofontas Dimitropoulos, Michail Vlachos, and Luca Deri The pace of technological research can be dizzying, and the past decade has been especially amazing for networking. We've seen Internet traffic swing from the web to BitTorrent to Netflix; we ve seen the source worms and hosts of other attacks expand from individuals to organized crime; we've seen whole new classes of networks, such as data centers, emerge. In a world where technology changes so quickly, stable, well-designed tools whose utility has stood the test of time are critically important. Tools let easily observe and understand networks even as they evolve. The longevity of tools such as tcpdump on one hand demonstrates their utility. On the other hand, it also shows their age: they were designed a long time ago. While networking has moved forward, so have many other fields, and applying new techniques to old problems can be a valuable contribution, deepening our understanding of networks. This paper is an excellent example of such a contribution. Tcpdump is a tool we've all used at some point. If you ve ever tried to use tcpdump
