Circuits as WAN connections battled successfully against packets for years because they guaranteed bandwidth, no matter what. If you bought a T-1 circuit, the service provider nailed up 1.5Mbps from ...

Packet switching is a network transmission method that sees data sent in small blocks called packets rather than as a continuous stream. Sending data in this way helps to improve the robustness and ...

The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user's mobile device and the base station and two core networks; one for circuit-switched ...

An old method of transmitting information (voice or data) through a system or network by establishing a persistent, dedicated connection ("circuit"). This connection consumes resources even when no ...

A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote ...

The fundamental technology underpinning the internet is called packet-switching. And Donald Davies was the first one to call it that. In the mid-1960s, Davies was a researcher with Britain's National ...
