2. NLANR/MNA
The mission of the NLANR Measurement and Network Analysis Group (NLANR/MNA) is to characterize the behavior of high performance connection (HPC) networks.
Network measurements are essential for assessing performance issues, identifying and locating problems (malfunctions, bottlenecks,
inefficiencies, incompatibilities, etc.) in ultrafast research networks
and in high-speed international links.

3. NLANR/MNA
To meet our research goals and support the community, we have created and are continuing to develop a Network Analysis Infrastructure (NAI). Two projects form the core of our research efforts:
the Passive Measurement and Analysis (PMA) project
the Active Measurement Project (AMP)
The NAI includes not only a growing collection of measurement data and multiple analyses, but also tools and methods, avenues for sharing information, and many collaborations (domestic and international) with other researchers both within and outside of the HPC network measurement community.

4. Passive Measurement and Analysis (PMA) project
Led by Joerg Micheel
Passive header trace data provides the means to study workload profiles in high speed environments, at measurement points strategically located to provide good overall network coverage.
Completely non-invasive, no impact on forwarding paths.
Currently take measurements at OC3 through OC48 speeds. Also working towards OC192c instrumentation on the Abilene backbone.

5. Available PMA Traces PMA Daily Traces Archive (~ 2 GB per day)
Many special traces available, such as a variety of OC48 trace data and long, contiguous traces, including:
Abilene-I, the first publicly available OC48c backbone trace
Auckland-IV, a 45-day continuous trace
Bell Labs-I, one-week contiguous Internet access IP header trace
Coming soon:
Leipzig-I, an illustrated continuous 5-day GPS-synchronized IP header trace
NCAR-I, a one-hour trace from our new NCAR Gigabit tap.

6. New Metrics and Real-Time Analysis for PMA
We have developed a link utilization analysis tool. This instantaneous bandwidth/histogram sequence tool uses CDF (cumulative distribution functions) histograms to characterize the distribution of the gaps between packets.
A first-phase release of a scalable real-time network sensor has been completed that implements packet length statistics. Current efforts involve the creation of a two site prototype, to be used for testing.

8. Active Measurement Project (AMP)
Led by Tony McGregor
AMP performs site-to-site
active measurements
(RTT, topology, and loss)
and analyses which enable
network researchers and
engineers to track problems
and/or changes in HPC
performance.
The monitoring mesh of 150 AMPs allows engineers to quickly identify the location, extent, and duration of network events.

9. Current AMP Research Activities
Moving AMP into new domains: other national meshes, deeper into campuses, more international sites, and a meta measurement system.
To facilitate this, NLANR/MNA is reimplementing the original AMP software into a package easily installed on a variety of hardware and software bases. The AMP package will be made freely available, with some limited support given.
We will encourage, promote, and manage a meta-measurement system, formed from selected cross-project measurements, creating measurement linkages between projects.

10. AMP IPMP
We have developed a new measurement protocol, the IP Measurement Protocol (IPMP), which allows Internet devices to insert time stamps into packets as they move through the network, creating an "audit trail" for Internet data.
In addition to designing and developing the protocol, we are utilizing it in the AMP network measurement mesh and on wireless networks.
We have submitted the protocol for standardization by the Internet Engineering Task Force (IETF).

13. International Collaborations
Just as the Internet has expanded into a global network, the more
advanced high-speed networks for scientific and academic research in
the United States and other countries are also growing and linking up
with one another. Many of the challenges that face intra-national
high-speed networks are more severe in international networks.
Network researchers and system administrators around the world are collaborating with NLANR/MNA researchers by hosting one or more of our AMP monitors and establishing measurement and analysis research projects of their own.

14. International Collaborations (Cont’d1)
We currently have AMP machines in Australia, Brazil, Canada, Finland, Germany, Holland, Hungary, Ireland, Japan, Korea, Mexico, New Zealand, Norway, Taiwan, and Thailand.
We are now conducting measurements from the AMP monitor on the NaukaNet link at StarLight to more than 30 sites in Russia.
Collaborating with the GLORIAD project ( An NLANR AMP will soon be deployed in Moscow.
We are in discussions regarding placing an AMP monitor in Beijing, China.

15. International Collaborations (Cont’d-2)
We are working closely with the Pacific Rim Applications & Grid Middleware Assembly (PRAGMA).
Australia and Korea have developed programs in collaboration with NLANR/MNA to create national AMP meshes, to instrument and characterize the performance of their domestic research networks.
The KISTI group in Korea has an NLANR AMP machine. Their own AMP mesh currently has 13 sites.
All seven Australian-owned AMP machines are in place ready for deployment into a mesh. Australia hosts an NLANR AMP in Sydney.
