Active Measurement Project (AMP) Led by Tony McGregor tonym@nlanr.net Current goals for AMP include moving it into new domains, such as, other national meshes, deeper into campuses, additional strategic international sites, and developing a “meta measurement” system – formed from selected cross-project measurements, creating measurement linkages between projects. Thanks to Warren Matthews who is creating an AMP Web Services implementation for us, based on the Internet2 Abilene Measurement Infrastructure (AMI) Service. Instructions and more information are available at: http://watt.nlanr.net/active/ampwebservices.html

AMP Code Reimplementation There are a growing number of organizations that realize they would benefit from a performance measurement system like AMP. To facilitate these needs of the community, we are undertaking the major task of reimplementing the original AMP software into a package easily installed and used, with limited support. The beta release of the AMPlet package (the software on each AMP monitor) is completed and is available at watt.nlanr.net/Software/AMP Work has begun on the central storage and analysis software.

AMP PathVis NLANR AMP has developed AMP PathVis, a prototype tool to aid in troubleshooting performance issues between a pair of end hosts. The core of the approach is a traceroute-based resource locator. The concept is based on the familiar visual analogy of a suburban rail network: the central line represents the path under test, and branch lines are selected by the tool because they show potential diagnostic routes (i.e., the AMP monitor closest to each hop along the path). This approach automates one of the most difficult tasks (selecting appropriate monitors from a large pool of candidates), thus supporting human interpretation of performance measures in a simple, but powerful, way.

10GigE Passive Monitors & Measurements One of our major accomplishments has been the development and deployment of 10-Gigabit Ethernet/OC192 passive monitors. We were the first in the world (2003) to deploy a 10-Gigabit passive monitor and take traffic traces from live networks (Sprint Paris). A 10-Gigabit passive monitor was deployed on the TeraGrid at SDSC in February 2004. These special traces are available to the networking community on our Web site. First to develop real-time applications capable of operating at 10 Gigabits (March 2004). First published 10-Gigabit Abilene backbone traces in June 2004.
