We investigate the minimum-energy packet scheduling problem for the multiaccess channel with K transmitters and a single receiver, assuming that packets arrive at each transmitter’s buffer at arbitrar...
The paper develops algorithms for minimizing the energy required to transmit packets in a wireless environment. It is motivated by the following observation: In many channel coding schemes it is possi...
We then devise a lazy online algorithm that varies transmission times according to backlog and show that it is more energy efficient than a deterministic schedule that guarantees stability for t...
The paper considers the problem of minimizing the energy used to transmit packets over a wireless link via lazy schedules that judiciously vary packet transmission times. The problem is motivated by t...
For future WDM MANs, optical packetswitching has been considered to be a promising paradigm that efficiently supports a wide range of Internet-based applications having time-varying and high bandwidth...
We present and evaluate opportunities and challenges for packet optical transport of residential and business data services from access to core networks. Presented solutions are evaluated based on sam...
Dynamic capacity migration between circuit and packet networks is an unexplored topic, but it can be an effective way to improve network utilization. We discuss techniques for dynamic capacity sharing...
Future packet transport networks need to cope with rapidly growing Internet traffic.Hybrid architecture approaches combining limited electronic with massive optical switching can help to overcome the ...
Despite twenty years of research, optical packet switching (OPS) struggles to find practical application. We analyze the capabilities and limitations of OPS, and conclude that OPS offers little compar...
We demonstrate how to realize 400 Gb/s optical packet switching for the first time. The key functions of optical packet generation, label separation, colorless O-OFDM payload detection and wavelength ...
Transport networks and technologies are undergoing transformation. The genesis of that transformation is packet switching embedded on transport equipment together with DWDM,OTN, and SONET/PDH switchin...
Advancements in photonic integration allow development of complex, large-scale circuits suited for future optical packet switched networks. We review our 8-channel InP monolithic tunable optical route...
We demonstrate 1.2-Tbit/s/port polarization-multiplexed optical packet (20 Gbit/s DQPSK × 30λ × 2 Polarization) switching and buffering. Our optical packet switch system with low polarization dependen...
We present a new forwarding-gate scheme using a single SOA-MZI. We show a bi-stable behavior with a 13.6 dB extinction-ratio and rise and fall times below 30ps. Error-free operation is achieved at 40 ...
For dynamic traffic change on packet/lightpath integration, all-bandwidth amplifiers and high dynamic-range packet receivers are developed. 80-Gbit/s colored optical packets and 8-lightpaths simultane...
