Hello All, Putting together a project "snapshot" for our new grid room . The constraints I have listed are; Multicasting, Bandwidth and Encryption (or lack thereof) Are the constraints for Multicasting a matter of "routers" outside of my institution or is it something else? Will I need a VPN JUST for a room node? We have a 100mb pipe out to the commodity internet. But I'm assuming that AG uses mostly I2. Your thoughts! Jeff Jeffrey L.
