NOC At Indiana University, try clicking on map or see Abilene traffic utilization (MRTG), Abilene Observatory. suports the collection and dissemination of network data associated with the Abilene network. piPES Performance Measurement Points (PMPs) are available form institutions around the world. Each institution operates their own PMP(s) and determines the tests available, the operating parameters, and the policy on who can use them. You can find out the details on each institution's PMP from their Information Page. See for example the OWAMP monitoring sites.
