Distance-Adaptive Routing and Spectrum Assignment (DA-RSA) in Rings
نویسندگان
چکیده
Distance adaptive spectrum allocation exploits the tradeoff between spectrum width and reach to improve resource utilization by tailoring the modulation format to the level of impairments along the path. We first show that the the distanceadaptive routing and spectrum assignment (DA-RSA) problem in mesh networks is a special case of a multiprocessor scheduling problem. We then develop a suite of efficient and effective DA-RSA algorithms that build upon list scheduling concepts. Our work explores the tradeoffs involved in DA-RSA algorithm design, and opens up new research directions that may leverage the vast literature in scheduling theory.

متن کاملSpectrum management techniques for elastic optical networks: A survey
In recent years, OFDM has been the focus of extensive research efforts in optical transmission and networking, initially as a means to overcome physical impairments in optical communications. However, unlike, say, in wireless LANs or xDSL systems where OFDM is deployed as a transmission technology in a single link, in optical networks it is being considered as the technology underlying the nove...
متن کاملImpact of Elastic Optical Paths That Adopt Distance Adaptive Modulation to Create Efficient Networks
We propose optical path routing and frequency slot assignment algorithms that can make the best use of elastic optical paths and the capabilities of distance adaptive modulation. Due to the computational difficulty of the assignment problem, we develop algorithms for 1+1 dedicated/1:1 shared protected ring networks and unprotected mesh networks to that fully utilize the characteristics of the t...
متن کاملSpectrum Defragmentation in Elastic Optical Networks
Elastic optical networks (EONs) provide fine bandwidth allocation granularity and enable scalable network management. In this paper, we review the strategies to alleviate spectrum fragmentation from both the preemptive and proactive perspectives. As for preemptive defragmentation, we investigate the characteristics of bandwidth fragmentation in EONs, and then discuss a fragmentation-aware routi...
متن کاملRouting and Spectrum Assignment in Spectrum Flexible Transparent Optical Networks
. The considered problem of routing and spectrum assignment (RSA) takes into consideration minimizing the length of the transmission distance under spectrum continuity constraints and the relationship between the traffic bitrates and the spectrum bandwidth. The proposed algorithms constitute modifications of the well-known Dijkstra's algorithm. The obtained results show that a significant reduc...
