As the telecom infrastructure evolves from circuit-switched to packet-switched architectures, the Class 5 switch, narrowband digital-loop carrier, and xDSL remote terminal will give way to the ...

To ensure that we can all watch YouTube without interruption, major Internet service providers must manage two very different switching technologies. Wide area "IP" networks made up of packet switches ...

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 ...

Now that network visionaries have been returned to Earth by the gravity of market realities, they're seeing that in order to not only survive but prosper, Internet Protocol (IP)-based private networks ...

In a $1.1 billion deal, Nortel Networks Corp. will supply equipment to Sprint Corp. for converting its existing local telephone service circuit-switch network to a packet-based system, the two ...

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 ...

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 ...

Everything you stream and share is broken into network packets. Learn how this enables the seamless flow of data that powers the internet. Network packets are small units of data that are sent from ...
