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 networks -- networks which break data up into chunks called packets before transport -- help make your business communications stable and efficient. Once used only for data ...

We develop a performance modeling methodology for product-form circuit-switched networks. These networks allow for: arbitrary topology and link capacities; Poisson and finite population arrivals; ...

Advances in Applied Probability, Vol. 18, No. 2 (Jun., 1986), pp. 473-505 (33 pages) This paper is concerned with blocking and loss probabilities in circuit-switched networks. We show that when the ...

Lucent last week broadened its circuit-to-packet migration offerings with a switch and components designed to let service providers evolve Class 5 networks to IP. Lucent last week broadened its ...

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 ...

The transition to packet technology for deliver ing both voice and data will be incremental. Carriers have billions invested in the circuit switched infrastructure and a voice service revenue model.

Google's system leverages optical circuit switching (OCS) to create direct, low-latency optical paths between TPU chips, ...

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 ...
