This paper investigates the spectrum fragmentation issue, which undermines bandwidth efficiency in elastic optical networks. After categorizing two-dimensional problem as and misalignment subproblems, this proposes joint routing assignment (RSA) algorithms to alleviate spectral lightpath provisioning process. The time complexity of two proposed are analyzed detail, both can run O(kdnC log C) time, where k is number shortest path algorithm, d maximum node degree network, n nodes C link...
It is of significance, but still remains a key challenge, to simultaneously enhance the strength and damping capacities in metals, as these two properties are often mutually exclusive. Here, we provide multidesign strategy for defeating such conflict by developing Mg-NiTi composite with bicontinuous interpenetrating-phase architecture through infiltration magnesium melt into three-dimensionally printed Nitinol scaffold. The exhibits unique combination mechanical improved strengths at ambient...
Abstract Bioinspired architectures are effective in enhancing the mechanical properties of materials, yet difficult to construct metallic systems. The structure-property relationships bioinspired composites also remain unclear. Here, Mg-Ti were fabricated by pressureless infiltrating pure Mg melt into three-dimensional (3-D) printed Ti-6Al-4V scaffolds. result was composite materials where constituents continuous, mutually interpenetrated 3-D space and exhibit specific spatial arrangements...
Elastic optical networks (EONs) enable network operators to have agile bandwidth management in the layer. In this paper, we investigate dynamic and adaptive defragmentation (DF) EONs with time-varying traffic using connection reconfigurations. We consider how design DF procedure a systematic way, study problems that not been fully explored so far. Basically, divide into four subproblems: “How reconfigure?,” “ How migrate traffic?,” “When “What solve them sequentially. For combination of...
We investigate the principle of how dynamic service provisioning fragments spectral resources on links along a path, and propose corresponding RMSA algorithms to alleviate spectrum fragmentation in network environments.
Bandwidth defragmentation, i.e., the operation to reconfigure existing connections for making spectrum usage less fragmented and misaligned, has recently been recognized as one of most important features elastic optical networks (EONs). In this paper, we propose a novel comprehensive bandwidth defragmentation algorithm that considers problems 1) When defragment? 2) What 3) How jointly. The proposed accomplishes through proactive network reconfiguration only reroutes portion connections. each...
Optical orthogonal frequency-division multiplexing (O-OFDM) technology has the elastic feature of allocating spectrum resources based on subcarrier slots with bandwidths at a few GHz or even narrower. This enables us to utilize link capacity more efficiently by splitting connection's traffic over multiple routing paths. In this paper, we propose novel dynamic multi-path provisioning algorithm for O-OFDM optical networks. The tries set up connections single-path in best-effort manner. When...
FeCoCrNi-Mo high entropy alloy/diamond composite coatings were successfully prepared by speed laser cladding. A scanning was adopted (>30 mm/s), and the effects of power, speed, diamond content on microstructure wear resistance coating studied. The processing parameters cladding had significant influence dilution ratio, graphitization diamond, coatings. When 3000 W power 50 mm/s, exhibited a uniform microstructure, lowest best resistance. enhanced with addition but microcracks also...
Flexible-grid elastic optical networks (EONs) have attracted intensive research interests for the agile spectrum management in layer. Meanwhile, due to relatively small allocation granularity, fragmentation has been commonly recognized as one of key factors that can deteriorate performance EONs. To alleviate fragmentation, various defragmentation (DF) schemes considered consolidate utilization EONs through connection reconfigurations. However, most previous approaches operate sequential...
Spectrum fragmentation limits the efficiency of spectrum utilization in elastic optical networks (EONs).
