Description
The talk will describe the Isabel technolgy for collaborating over the Internet, which has been developed and used during the last 10 years to perform distributed conferences, workshops, meetings, etc. Isabel is a multipoint group collaboration tool for the Internet, which implements an innovative service concept for synchronous collaborations with audience interconnection in distributed classrooms, conferences, meetings, etc. The development of Isabel started in 1993 for the distribution of the RACE Summer Schools on Advanced Broadband Communication (ABC93-6) over the first ATM pilot networks. The adaptation of Isabel to the broadband Internet (including no QoS control, VPNs, IPv4/IPv6 transition scenarios, mixtures of unicast and multicast) is reaching maturity and its use over the existing research networks can enable collaboration within universities and/or research centers, in distributed conferences, workshops, clasrooms or meetings. The Isabel service concept has been also tunned and improved since then with the feedback coming from the realisation of many distributed events, such as ABC9x, Global360x, IDC9x, Global IPv6 Summitts, Internet NG Workshops or Telecom I+D, where dozens of sites and hundreds of persons have participated each year. Additionally, platform deployment techniques have been developed which automate most of the steps of platform creation. Those techniques make use of the new Web architecture, using XML, XML-RPC or Web Services having many paralelisms with the service or resource GRID architecture. During the first Isabel trialsplatform deploymentwas performed manually with a very large effort. The deployment of platforms uses today XEDL, an XML based platform definition language which automates the management by allowing incremental platform definition during the event creation. The various components, sites or servers are added to the platform definition in XEDL during the event preparation, which will allow automatic platform launch and operation as described below.
