Transport protocols and bulk file transfer

All,

On behalf of the perfSONAR workshop executive committee, we would like to invite you to the first NSF-sponsored workshop on the perfSONAR Network Measurement Infrastructure, to be held July 8-9, 2010 in Arlington, VA. A short version of the call for participation is attached, and the full version of the call, along with more information on perfSONAR, is available at <http://www.internet2.edu/workshops/nsf-perfSONAR/>

Briefly, the goal of the workshop is use perfSONAR as a focus to cross-fertilize ideas from the network research community and the needs of the research and education networks around the world. The workshop will bring together researchers, applications developers, network operators, and others with an interest in network research and network performance measurement. Researchers will benefit by presenting relevant research projects, hearing operational and engineering needs, and learning about the protocols and system as a distribution channel for research results.  Operators and engineers will benefit through exposure to research results and by articulating engineering challenges and research needs, and learning how perfSONAR might meet some of those needs.

If you are interested in attending (or presenting), please reply to by April 19, 2010, including a short paragaraph on your measurement interests in the workshop (and, if you'd like to give a talk, a separate submission on what you'd like to present). NOTE: space at the workshop is very limited; participation is based on reviews of these paragraphs. If selected, your paragraph would be made public. We would also appreciate if you could look at the detailed call's potential focus areas and tell us what interests you the most; we'll use your responses to help craft the breakout sessions of the workshop.

Please feel free to contact me with any questions about the event,

--Susan

Call for Participation

NSF-sponsored Workshop on the perfSONAR Network Measurement Infrastructure
July 8 and 9, 2010 in Arlington VA
http://www.internet2.edu/workshops/nsf-perfSONAR/

perfSONAR is an extensible, standards-based network performance
monitoring middleware infrastructure, that not only facilitates the
ability to solve end-to-end performance problems on paths crossing
several networks but also enables network-aware applications. This
infrastructure supports performance data collection and exchange
between multiple networks using well-known protocols and formats. More
than 68 entities around the world, ranging from backbone networks to
universities to government laboratories have deployed perfSONAR.
perfSONAR makes it relatively easy to take an experimental measurement
tool, incorporate it into perfSONAR, and publish and archive the
results of the tool.

The goal of the workshop is use perfSONAR as a focus to
cross-fertilize ideas from the network research community and the
needs of the research and education networks around the world. The
workshop will bring together researchers, applications developers,
network operators, and others with an interest in network research and
network performance measurement. Researchers will benefit by
presenting relevant research projects, hearing operational and
engineering needs, and learning about the protocols and system as a
distribution channel for research results.  Operators and engineers
will benefit through exposure to research results and by articulating
engineering challenges and research needs, and learning how perfSONAR
might meet some of your needs.

For more information on perfSONAR, see <http://psps.perfsonar.net/> (home
of the Perl-based effort in the U.S., including links to use cases) and
<http://www.perfsonar.net/> (home of the international project). 
A tutorial given at the most recent Asia-Pacific Advanced Networking
meeting is available off the materials page of the workshop web site,
<http://www.internet2.edu/workshops/nsf-perfSONAR/>.

The data currently available through perfSONAR tends to be that useful
for end-to-end performance debugging: Link utilization and errors,
Traceroute beacons & looking glasses, Active measurments and active
measurement results (Latency (one-way and round-trip), Loss, Throughput),
and servers to test hosts and last-mile links (NDT and NPAD).  In addition,
Internet2 makes available anonymized Netflow data, BGP and IGP data,
syslog data from our routers, and an interactive router query.

Potential focus areas include: Research use of perfSONAR (use it for
research or publish research results), perfSONAR tools and services
(publishing new information such as middleware or application logs,
missing pieces, tool limitations or expansion), and Operational issues
(increasing routine testing, including internationally; deployment
challenges; use in performance debugging; data sharing issues).

To Participate:
The workshop is open to all, but is limited to no more than 80 people,
to be selected by an executive committee.  If you are interested in
attending, we would like you to send a few sentences or a paragraph
describing your interest (in plain text or PDF) to 

 by April 19, 2010.  Please also
indicate if any of the focus areas are particularly interesting; we
will use the results to craft breakout sessions during the workshop.
