Abstract: this paper we discuss the storage andbandwidth requirements for data gathered bypassive Internet measurements. We considerpassive network measurements utilising highprecisiontime-stamping as the most accuratemeans to deliver an a view of today's packetnetwork dynamics

    • ...Solely from protocol headers, monitoring applications can infer useful information and network metrics, while this approach can reduce significantly the storage space [2] and thus increase retention...

Let us consider a computer system with a gigabit Ethernet NIC and 66MHz/64bit PCI bus and 1 Gbyte RDRAM (800MHz/16bit) and 2 GHz Pentium 4. The n the theoretical max transfer rate of a gigabit Ethernet NIC is 125 Mbytes/sec, PCI bus is 533 Mbytes/sec, and dual channel RDRAM (800MHz/16bit) is 3.2 Gbytes/sec [6, ...
