Instrumentation and Measurement (I&M): GIMI and GEMINI Design Topics at GEC15
Tuesday, October 23, 8:30am - 10am
Room:
Session leader: Harry Mussman (GENI Project Office, Raytheon BBN Technologies)
Description
This I&M session will focus on the key issues of interest to both the GIMI and GEMINI projects, as they continue to work towards a comprehensive set of I&M tools for GENI experimenters and for infrastructure measurement. In particular, we will consider the services and functions that can be used by both the GIMI and GEMINI projects.
We will form teams that can resolve these issues.
Finally, we will discuss the I&M goals for the next 4 months, particularly how to best support experimenters and those doing infrastructure measurement.
Agenda
This is a tentative agenda, which may change.
