Title: BAG (Continuous Round Robin Packet Capture)

Abstract

Bag is a miniature pcap filter which takes pcap input (or input off the wire) using a bpf filter, if specified, and then writes the output to stdout or a file (in pcap format). It depends for some aspects of its functionality on a libpcap library which uses a shared memory packet capture ring bugger. There are two build in modules: chcksum and session. the build in chcksum modules is used to anonymize the ip addresses and repair any checksums in the stream. % bag -r /tmp/*.pcap -Cchucksum, 128.1 65: 10.10 The session module generates sessions which are defined as a series of packets that have two things in common. the first is a unique five-tuple composed oi an IP protocol, IP source address, IP source port, IP destination address, and IP destination port. The second is that if the originating packet is associated with a bi-directional service such as ftpltcp, characteristics and data will be kept for both flows involved with the service. The only protocols evaluated beyond the IP header are ICMP, TCP and UDP. A session can last for as long as bag is running. However, under normal conditions, sessions are generated every time they appear tomore » have closed down. There is a man page included with the distribution which goes into more detail.« less

  • Individual hydrocarbons, aldehydes/ketones, PAH, volatile organics on soot, sulfate, HCN, phenols and ammonia were selected from eight European automotive industries for round robin testing. Known and unknown standard mixtures and known and unknown exhaust samples led to a confidence range from 9 to 390%. Special standardization lowered the range to less than 50%. International standardization and a new round robin testing with increased participants including CRC- and CEC-working groups is recommended. The Committee of Common Market Automobile Constructors (CCMC)/Emission Research Management Committee (ERMC) recommends to start with PAH and aldehydes/ketones.
  • In 1976, Pacific Nortwest Laboratory initiated a program to determine the state of the art of methods of analysis for geothermal fluids. A meeting between government agencies and laboratories led to agreement on 40 parameters for evaluation in a round-robin field testing program. Two round-robins were conducted with approximately 20 laboratories participating in the analysis. Statistical analysis of the data from these tests shows that the greatest range of results was obtained for the species silver, aluminum, antimony, fluoride, bromide, iodine, phosphate and total hydrogen sulfide. In addition, the constituents rubidium, coper, managanese, lead, and zinc showed a high degreemore » of variability for the brine with low total dissolved solids. 19 refs.« less
  • A round robin test program was initiated by the CIGRE TF 15-06-05 in 1986 to evaluate three methods, donoted as A, B and C, proposed by the Task Force to test the water-treeing propensity of extruded cable insulation. This report covers the second round, conducted at the University of Connecticut under EPRI sponsorship, to evaluate Method A and Method B. Method A is designed to test materials subjected to non-uniform electric fields, such as those arising at the tips of protrusions. Method B is designed to test materials exposed to uniform or quasi-uniform fields. The electrically stressed material samples aremore » immersed in a salt solution and aged for prescribed periods of time at either room temperature (Method A) or at 70{degrees}C (Method B). They are, then, sliced, dyed in a methylene blue solution and examined under an optical microscope to determine the nature and extent of treeing. This report covers the testing of as standard crosslinked polyethylene (XLPE) and two different brands of tree-retarding XLPE obtained from European and US sources. Variations of the domestic samples were produced by extracting their ionic impurities with deionized water. The objective of the evaluation was to determine whether the CIGRE test methods could consistently distinguish between the various samples for their water-treeing propensity. The report describes, in detail, the test cells, the testing methods and the results obtained. It also describes the modifications made to the cell used in Method A to improve the consistency of its results. 4 refs., 29 figs., 7 tabs.« less
