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 persona lized communication. We leverage the Internet's low cost of entry for servi ce creation, provision, deployment, and integration. In this article we pre sent our solutions to signaling, easy service creation, resource reservatio n, admission control, billing, and security in the ICEBERG network architec ture.
