A set of events and experiences have let to the decision of starting a conducting-over-ip (CoIP) project.
These events spiked the idea of putting together a “Conducting over IP” project. Note that the initial ambitions where to set up a trans-atlantic session. However due to limited lack of partners in US and the physical distance the focus became national and trans-european.
The over all internet is essentially a network of networks. Tens of thousends of companies, research and academic institutions operate their own IP based networks. They are call Internet Service Providers (ISP). All these ISPs are interconnected, and customers of one ISP may transmit data to customers of a different ISP. Data will flow directly between two ISPs if they have a direct (peer) connection between them. If not, data will transit one or more other ISPs before entering the destination ISP.
Most countries in the world have a dedicated research and educational ISP known as a National Educational and Research Network (NREN) . UNINETT and FCCN are such networks, Norwegian and Portuguese respectively. All NRENs are interconnected directly or via backbone networks operated in cooperation by NRENs. Hence when a Norwegian student sends data to a Portuguese student, the data will flow across only NREN-type of networks, i.e. the academic internet. It turns out most NRENs today have significantly more available capacity than other types of ISPs. Hence students and researcher have the option to communicate in advanced ways over their networks without having to negotiate for extra capacity or shorter delays.
