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 ...

A digital network technology that breaks up a message into smaller chunks (packets) for transmission. Unlike circuit switching in traditional telephone networks, which requires the establishment of a ...

Back in the 1999 heyday of prosperity in the communications segment, everyone from chip vendors to switch makers to service providers were talking up VOIP (voice over Internet Protocol). The ...

Convergence is a dominant theme in modern telecommunications and networking, and it touches virtually all levels of the communications hierarchy. In the core, carriers desire a simple, unified network ...

Verizon Communications announced a deal with Nortel Networks on Tuesday, the latest carrier moving to add packet-switching technology to its voice network. Other carriers are also slowly moving toward ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

Description: A qualitative and quantitative study of the issues in design, analysis, and operation of computer communication and telecommunication networks as they evolve toward the integrated ...
