What is AG?(1) http://www.mcs.anl.gov/fl/accessgrid/ The Access Grid is a system that enables group to group collaboration across the internet by providing multiple video and audio streams among them. It is designed in Argonne National Laboratories. The Access Grid consists of many AG nodes around the country. Currently there are almost 20 nodes in US. We propose putting them throughout DoD MSRC and DC 1/14/2019

What Is AG?(2) The access grid project focus is to enable groups of people to interact with grid resources and to use the grid technology to support group to group collaboration at a distance Improved the user experience Provide a sense of presence Support natural interaction modalities Relatively unsophisticated shared document model. Can use with WebEx Centra etc. 1/14/2019
