To engage Internet2 users in an exploration of peer-to-peer, real-time communications, these users require connectivity. Superior networking connectivity alone is not sufficient. Directory and call routing middleware must be deployed to connect applications with applications and ultimately users with users. Internet2 is working to grow this connectivity and to encourage large-scale experimentation at the edge. The best applications will combine peer-to-peer design principles with new, centrally-managed enterprise services. Identity management, authentication, location services, and rich presence are all best implemented by the enterprise. Several new Internet2 initiatives are surveyed.
