Power Consumption Evaluation of Circuit-Switched Versus Packet-Switched Optical Backbone Networks
... The way that traffic demands traverse the network is different in packet switching and circuit switching. Under the packet switching paradigm, all the traffic in a node—i.e., not only the originating and terminating, but also the transit traffic—is processed at the router in the IP/MPLS layer, as sh ...
