Topics in emerging technologies:Cost optimization methods in the design of next generation networks
A key development of telecommunication systems during the past two decades has been the evolution from the circuit-switched network toward the packet-switched network paradigm. Many operators are now migrating their PSTNs from circuit switched networks. This new approach is often called the next-gen...

A key development of telecommunication systems during the past two decades has been the evolution from the circuit-switched network toward the packet-switched network paradigm.

In this article the migration of Iceland Telecom's circuit-switched PSTN towards NGN is described.
