The Wires

The Future of Wires

Concern about the performance of wires in scaled technologies has led to research exploring other communication methods. This paper examines wire and gate delays as technologies migrate from 0.18m to 0.035m feature sizes to better understand the magnitude of the wiring problem. Wires that shorten in length as technologies scale have delays that either track gate delays or grow slowly relative t...

Sharing More than the Wires

Logistical Networking is the global scheduling and optimization of data movement, storage and computation based on a model that takes into account all the network's underlying physical resources. In this paper we contrast Logistical and Active Network as approaches to flexible implementation of advanced network protocols. We describe the Internet Backplane Protocol, a simple mechanism we have d...

Digital wires

E lectrical wires transport energy and information and often both. For example, electrical power cords deliver electrical energy from wall outlets to computers, whereas Ethernet cable transports information in the form of electrical pulses from the internet modem to the computer and back. USB cables are used to both charge the battery of MP3 players and to load digital music on the player. Desp...

Quantum Wires

Optical 'shorting wires'.

Connecting lumped circuit elements in a conventional circuit is usually accomplished by conducting wires that act as conduits for the conduction currents with negligible potential drops. More challenging, however, is to extend these concepts to optical nanocircuit elements. Here, following our recent development of optical lumped circuit elements, we show how a special class of nanowaveguides f...
