The Network Core

Having examined the Internet's edge, let us now look into more deeply inside the network core - the network of packet switches and links that interconnects the internet's end systems. The following figure highlights the network core with thick, shaded lines.

Multiplexing in Circuit-Switched Networks

A circuit in a link is implemented with either frequency-division multiplexing (FDM) or time-division multiplexing (TDM). With FDM, the frequency spectrum of a link is divided up among the connections established across the link. Particularly, the link dedicates a frequency

Packet Switching Versus Circuit Switching: Statistical Multiplexing

Having explained circuit switching and packet switching, let us compare the two. Opponents of packet switching have frequently argued that packet switching is not appropriate for real-time services (for example, telephone calls and video conference calls) because of its
