DSG allows massive numbers of OpenSim users to interact live with each other without lag. For today’s test, 12 logged into region mosesdsg2, and 12 logged into mosesdsg5; yet each one of the 24 could see every other one of the 24, and chat and communicate together. Users were logged in from 9 states, and 3 countries. The Office Hours load test is part of preparations for much larger exercises to be conducted by STTC. Intel members of the MOSES Community include Robert Adams, Mic Bowman, Dan Lake, and Kitty Liu. *Selected quotes* *Bandwidth increases quadratically with the number of users. For n users, each making a move, the server sends n(n-1) updates. * n=2; 2 updates n=5; 20 updates n=10; 90 updates n=20; 380 updates n=50; 2,450 updates n=100; 9,900 updates n=200; 3,980 updates n=500; 249,500 updates n>500; n*n updates See also: U.S. Army Offers MOSES 3D Web System for Non-Army Researchers<http://sitearm.wordpress.com/2011/05/16/u-s-army-offers-moses-3d-web-system-for-non-army-researchers/> Distributed scene graph to enable thousands of interacting users<http://www.pap.vs.uni-due.de/MMVE10/papers/mmve2010_submission_7.pdf> Military Open Simulator Enterprise Strategy (home page)<http://brokentablet.arl.army.mil/> Posted in 3D Web <http://sitearm.wordpress.com/category/3d-web/>, MOSES<http://sitearm.wordpress.com/category/moses/>, News <http://sitearm.wordpress.com/category/news/>.
