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 into multipurpose packet switched networks. This new app...
