ICEBERG: an Internet core network architecture for integrated communications

In the ICEBERG project at UC Berkeley, we are developing an Internet-based integration of telephony and data services spanning diverse access networks. Our primary goals are extensibility, scalability, robustness, and personalized communication. We leverage the Internet's low cost of entry for service creation, provision, deployment, and integration. We present our solutions to signaling, easy service creation, resource reservation, admission control, billing, and security in the ICEBERG network architecture.
