Errata for SIGCOMM CCR (Vol. 44, Issue 1, January, 2014) Estimating Internet Address Space Usage through Passive Measurements

چکیده
We discovered three errors in our analysis for this paper, which have slight effects on the results we reported in Sections 1, 4, and 5. The first error was a syntax error in the filter we used to exclude spoofed source traffic; this filter erroneously excluded 170,501 and 153,974 /24 blocks respectively from the UCSD and MERIT darknet traffic samples, although some of these we observed at the SWITCH vantage point anyway. Once we corrected this error, the net total number of /24 blocks discovered by our passive methods increased by 65,551 (from 3,881,054 to 3,942,605), and the number of such blocks that were not also observed via our active methods increased by 19,211 (from 452,007 to 471,218). We had also reported that our passive measurements for conducting an Internet census could reduce the overhead of an active approach by 37.9%, but correcting our filters increased this overhead reduction to 38.5%.

A retrospective analysis of reported errata in five leading medical journals in 2012
BACKGROUND Although medical publications are frequently used as the source of information, the prevalence of errata remains unclear. The objective of this study was to examine peer-review and publication processes of medical journals as well as to determine the occurrence of reported errata in medical journals and timeliness in identifying and correcting errata. METHODS Five medical journals,...
متن کاملUnderstanding Block - level Address Usage in the Visible Internet ( Extended ) USC
Although the Internet is widely used today, we have little information about the edge of the network. Decentralized management, firewalls, and sensitivity to probing prevent easy answers and make measurement difficult. Building on frequent ICMP probing of 1% of the Internet address space, we develop clustering and analysis methods to estimate how Internet addresses are used. We show that adjace...

متن کاملShining Light on Dark Address Space
In this report, we explore the degree to which commercial strategies, peering disputes, network failures, misconfiguration, and occasionally, malicious intent, lead to a partitioning of Internet topology. Specifically, we present a three-year study of the one-sided differences in Internet provider reachability. We focus on “dark address space”, or the range of topology accessible from one provi...
