Passive Measurement and Analysis is an National Laboratory for Applied Network Research  Measurement and Operations Analysis Team (NLANR MOAT) research project located at San Diego Supercomputer Center.

PMA is part of the Network Analysis Infrastructure. Active network measurements are being carried out by the AMP project.

The passive Internet data collection infrastructure consists of a growing number of monitors located at aggregation points within HPC networks, the vBNS and Internet2 Abilene. We are working on complementing the current infrastructure and welcome suggestions and invitations for new measurement points.
