Enabling Virtual Organizations, California Institute of Technology
Data Center Description
The EVO (Enabling Virtual Organizations) System (http://evo.caltech.edu) is based on a new distributed architecture, leveraging the 10+ years of experience of developing and operating the large distributed VRVS collaboration system now in production. The primary objective of EVO is to provide an improved system and a service to the LHC and other major High Energy Physics programs that fully meets the requirements for usability, quality, scalability, adaptability to a wide range of working environments, reliability and cost. The EVO infrastructure automatically adapts to the prevailing network configuration and status, so as to ensure that the collaboration service runs without disruption. Because EVO is able to perform end-to-end monitoring, including the end-user's computer as well as the network infrastructure, we are able to inform the user of any potential or arising problems (e.g. excessive CPU load or packet loss) and, where possible, to fix the problems automatically and transparently on behalf of the user (e.g. by switching to another server node in the network, by reducing the number of video streams received, by adjusting audio volume, etc.).
