The rapid growth of traffic inside data centers caused by the increasing adoption cloud services necessitates a scalable and cost-efficient networking infrastructure. Space-division multiplexing (SDM) is considered as promising solution to overcome optical network capacity crunch support cost-effective scaling. Multi-core fiber (MCF) regarded most feasible efficient way realize SDM networks, its deployment seems very likely issue inter-core crosstalk (XT) not severe over short link spans (<1...
Disaggregated rack-scale data centers have been proposed as the only promising avenue to break barrier of fixed CPU-to-memory proportionality caused by main-tray direct-attached conventional/traditional server-centric systems. However, memory disaggregation has stringent network requirements in terms latency, energy efficiency, bandwidth, and bandwidth density. This paper identifies all key performance indicators a disaggregate IT resources while summarizing progress importance optical...
The disaggregated dRedBox Data Centre architecture is proposed that enables dynamic allocation of pooled compute and memory resources. An orchestration platform described algorithms are simulated demonstrate the efficient utilization IT infrastructure.
We investigate the time-dependent crosstalk characteristics of trench-assisted multi-core fibers in a temperature controlled environment. Results indicate that temperature, PRBS length, modulation format and signaling rate impact intensity volatility inter-core crosstalk.
This paper proposes and experimentally evaluates a fully developed novel architecture with purpose built low latency communication protocols for next generation disaggregated data centers (DDCs). In order to accommodate capacity needs of IT elements (i.e., CPU, memory), this makes use high-capacity circuit-switched optical network interconnecting various end points that are equipped multi-channel silicon photonic based integrated transceivers. move further decrease the perceived between...
A new disease of barbary wolfberry(Lycium barbarum L.) fruit, causing fruit rot in the drying process by insolation method green house, was found. Alternaria alternata and Cladosporium herbarnm consistently isolated from diseased fruits. The lesions both were initially observed on stalk or wound.
Two parallel OCS topologies are proposed that deliver 95 nsec round-trip latency on disaggregated optical data center in a box system. They offer 40% cost and 68% power consumption efficiency at maximum IT resource utilization.
A wavelength-dependent crosstalk calculation formula for bi-directional MCF with unequal core pitches is derived. SDM-WDM based DCN simulations indicate that density and layout play a significant role on optimizing various scales of DCNs.
Space division multiplexing using multi-core fiber (MCF) is a promising solution to cope with the capacity crunch in standard single-mode based optical communication systems. Nevertheless, achievable of MCF limited by inter-core crosstalk (IC-XT). Many existing researches treat IC-XT as static interference, however, recent research shows that varies time, wavelength and baud rate. This inherent stochastic feature requires comprehensive characterization behaviour its application practical...
The traditional microcircuit card generally adopts the Crypto-1 private encryption algorithm, and its main components are a pseudo random number generator (PRNG), 48-bit linear feedback shift register (LFSR) nonlinear function. This paper mainly starts off from perspective of design flaw Filter Function algorithm: first, characteristics sequence generated when reader swipes card, same is re-established after each power failure; then, by controlling time position moment acquires energy...
Abstract In order to screen out the best culture conditions for growth of callus Actinidia arguta , leaf and stem were used explore effect different light intensity on multiplication. The results showed that, could promote synthesis anthocyanins in callus, low keep maintain a healthy physiological state with green color compact structure. addition, there was negative correlation between multiplication, stronger intensity, more severe browning. optimal condition multiplication dark...
Hemagglutination titer of crude lectin from four traditional chinese medicine was detected. Lectins Radix Polygalae and Saxifraga stolonifera agglutinated red blood cells rabbit, rat chook potently. Heteropappus hispidus (Thunb.) Less also the three kinds cells, but hemagglutination lower. effect Lepisorus waltonii (Ching) Ching only appeared in cells.
Five triterpenoids were isolated from Gentiana farreri, which was used as traditonal Tibetan medicine in the treatment of some diseases. Their structures identified as: pseudotaraxasterol (1), lupeol (2), ursolic acid (3), 2α, 3ß-dihydroxylursolic (4), 2α,3ß-dihydroxyloleanolic (5). All these compounds G. farreri for first time. The cytotoxic activity on growth HepG-2 cells all investigated MTT assay, results showed that compound 3, 4, 5 have high activity, IC50 is 100.88, 13.03, 13.19...
A novel random walk based model for inter-core cross-talk (IC-XT) characterization of multi-core fibres capable accurately representing both time-domain distribution and frequency-domain representation experimental IC-XT has been proposed. It was demonstrated that this is a generalization the most widely used in literature to which it will converge when number samples measurement time-window tend infinity. In addition, consistent with statistical analysis such as short term average crosstalk...
