I wasn't at the last meeting, but from the notes it looks like Matt and Will informed folks that I have been writing a BTC tool called 'cap'. The tool is a little different from Matt Mathis' cool treno tool that has been talked about in this group for some time. The key difference is that cap has both a sending and receiving tool, whereby treno depends on ICMP packets for the "ACK stream". Both approaches have their good and bad points. Recently I have started running some preliminary tests across the NIMI mesh of cap, treno and stock BSD TCP. The plan is to have some findings about the performance of both cap and treno in comparison to a real TCP implementation to present at the Pittsburgh meeting. The hope is that this will shed some light on whether or not we can come up with a good tool to measure BTC. In addition, this exercise may shed some light on some aspect of the BTC framework document that needs work. I look forward to discussing this with folks at the IETF meeting. Any input/comments would certainly be appreciated.

Hi Soo-- Unfortunately the source code to pathchar has not yet been released to the public at large. However, there are at least two open-source alternatives, based on the algorithms used in pathchar, as described by a talk that Van Jacobson gave at MSRI in 1997. pchar is a version that I did while at Sandia National Laboratories. It runs on a variety of UNIX systems, and runs several different analysis algorithms over both IPv4 and IPv6. pchar is available from: http://www.employees.org/~bmah/Software/pchar/ clink ("characterize links") is another implementation by Allen B. Downey of Colby College. His version runs on Linux, and it has some options for more accurate timestamping of packets within the Linux kernel. clink is available from: http://www.cs.colby.edu/~downey/clink/ Both the pchar and clink Web pages have some links to other related information about pathchar. (Why are there two versions? We started independently and neither of us quite realized what the other was doing until we were mostly done.) > By the way, I have a question ... > What's the difference between a bottleneck b/w and an available b/w? > Which of b/w's can "pathchar" give me? The available bandwidth along a path between two Internet hosts is equal to the bandwidth at the bottleneck. In other words, in the context of pathchar, they're the same thing. Hope this helps...

This draft is a work item of the IP Performance Metrics Working Group of the IETF. Title : Network performance measurement for periodic streams Author(s) : V. Raisanen, G. Grotefeld Filename : draft-ietf-ippm-npmps-02.txt Pages : 19 Date : 12-Jul-00 This document describes some of the issues associated with application-level measurements of network performance for periodic streams. An example application would be the testing of Dst-Src routes for use as bearer for multimedia streams. In this document, the reader is assumed to be familiar with the terminology of the Framework for IP Performance Metrics RFC 2330 [1]. This document is parallel to A One-way Delay Metric for IPPM RFC 2679[2]. A sample metric is described that is suitable for application-level measurement for streaming multimedia over IP. Using such a measurement, transmission service of a network is probed with a traffic stream similar to that of the application of interest, which is likely to be very dissimilar to the Poisson inter-arrival interval described in [2].

To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages.

To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <20000724141726.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-ietf-ippm-loss-pattern-03.txt --OtherAccess Content-Type: Message/External-body; name="draft-ietf-ippm-loss-pattern-03.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <20000724141726.I-D@ietf.org> --OtherAccess-- --NextPart--
