Collaboration systems enable people in remote places to communicate and cooperate together. It will bring substantial benefits to Internet users if we can build an integrated collaboration environment, which combines conferencing, streaming, instant messaging as well as other collaborations into a single easy-to-use, intuitive environment. However, traditional collaboration system can only provides limited collaboration capabilities to a small group people in a local or private community. They have features that sometimes can be compared but often the systems make implicit architecture and implementation assumptions that hamper interoperability and functionality.
The objective of the tutorial is to give a comprehensive overview of well-known multimedia collaboration technologies and introduce a more general framework to cover the wide range of collaboration solutions and allow different users from the different communities to collaborate. This tutorial will present Web-Services based solutions and discuss two open source systems í░NaradaBrokeringí▒ and í░Global Multimedia Collaboration Systemí▒ as an illustration about how to apply Web-services and overlay networking in massive scale collaborations.
Collaboration, Web-Services, Multimedia, Overlay Networking, XGSP, NaradaBrokering, H.323, AccessGrid, RealStreaming.
The target audience consists of researchers from technical industries, research laboratories, and academic environments, who are working on multimedia collaboration services. There is no prerequisite knowledge required.
