The NLANR Active Measurement Program (AMP) for HPC awardees is
intended to improve the understanding of how high performance networks
perform as seen by participating sites and users, and to help in problem
diagnosis for both the network's users and its providers.
See RTT Measurements for results.
The Andover News publishes the Internet Traffic Report that monitors
the flow of data around the world and displays a value between zero and
100. Higher values indicate faster and more reliable connections.
The Cooperative Association for Internet Data Analysis is a
collaborative undertaking to promote
greater cooperation in the engineering and maintenance of a robust, scalable global Internet
infrastructure. provides a neutral framework to support these cooperative endeavors.
Ongoing data collection at CAIDA.
The Common Solutions Group (CSG) with the
Advanced Network and Services
are working to
create technology and infrastructure to
allow users and service providers (at all
levels) to have an accurate common
understanding of the performance and
reliability of given Internet paths and to
have an accurate common understanding
of what segment of a given Internet path
limits that performance and reliability.
Distributed Internet Measurements and Simulations
DIMES is a distributed scientific research project, aimed to study the structure and
topology of the Internet, with the help of a volunteer community (similar in spirit
to projects such as SETI@Home).
This web portal provides access to a significant portion of the ESnet router interface
statistics based on SNMP counters.
The purpose of the IEPM-BW project is to develop and use an
infrastructure to make active end-to-end application and network
performance for high performance network links such as are used
worldwide by Grid applications and other academic and research (A&R)
applications deployed over high performance network such as ESnet,
Internet2 and other A&R networks in the developed world.
This provides an overview of DAAC Science Data outflow.
Graphs are provided for daily quantity of data leaving selected DAAC
and principal investigator sites, plus active measurements of
achievable throughputs. TRaffic characterization information is also
Measurement and Operations Analysis Team (MOAT) will
work closely with the two
other NLANR activities, the Distributed Applications
Support Team (DAST) and the National Center
for Network Engineering (NCNE).
These three activities are the successor of the original NLANR
collaboration, which formally started in 1995.
The Network Measurements Working Group of the
Global Grid Forum (GGF)
focuses on metrics of interest to grid applications and works in
collaboration with, other standards groups such as the
IETF IPPM WG
Internet2 End-to-end initiative. The NMWG will determine which
of the metrics defined by such groups are relevant to Grid applications,
and pursue standardization of metrics of shared interest to multiple
The Network Weather Service is a distributed system that periodically monitors
and dynamically forecasts the performance various network and computational
resources can deliver over a given time interval.
