In the recent years, the elasticity implemented in an optical spectrum domain is found to be one of the key aspects under optical fiber communication technology. Here, the Orthogonal Frequency Division Multiplexing $\left(OFDM\right)$ implemented by re-configurable optical add–drop multiplexors $\left(ROADMs\right)$ and bandwidth variable Wavelength Selective Switches $\left(WSSs\right)$ together is the emergent technology that facilitate the elasticity. However, the spectrum allocation process retaining Spectrum Continuity Constraints ($SCC$) is one of the major aspects in data communication methodology under $EON$ (Elastic Optical Network). In this regard, it is worth mentioning that the backtracking spectrum allocation algorithms are inevitably applied in an $EON$ which is inherently exempted from spectrum conversion facility. In this study, various aspects of spectrum allocation strategies are considered and an innovative idea (best of our knowledge and belief) — A non-backtracking spectrum allocation ($NBSA$) algorithm is developed and applied in an $EON$ well equipped by spectrum converters as well. The prime objective of this algorithm is to increase the network throughput with less spectrum allocation time in comparison to the traditional backtracking spectrum allocation algorithms. Moreover, to investigate the efficiency of the proposed algorithm, $EON$ of various sizes are considered and comparison measurements are done to the traditional backtracking algorithm. Here, an important and subtle observation in algorithmic efficiency is noted along with the increasing size of the networks.

近年来，发现在光谱领域中实现的弹性是光纤通信技术下的关键方面之一。在这里，正交频分复用$（ØFd\mathrm{中号}）$ 由可重新配置的光分插复用器实现 $（\mathrm{[R}Ø\mathrm{一种}d\mathrm{中号}s）$ 和带宽可变的波长选择开关 $（\mathrm{w\; ^}\mathrm{小号}\mathrm{小号}s）$一起是促进弹性的新兴技术。但是，频谱分配过程保留了频谱连续性约束（$\mathrm{小号}CC$）是在以下情况下数据通信方法学的主要方面之一 $ËØñ$（弹性光网络）。在这方面，值得一提的是，回溯频谱分配算法不可避免地应用于$ËØñ$固有地免于频谱转换功能。在这项研究中，我们考虑了频谱分配策略的各个方面，并提出了一个创新的想法（据我们所知和所信）–非回溯频谱分配（$ñ乙\mathrm{小号}\mathrm{一种}$）算法的开发和应用 $ËØñ$频谱转换器也配备齐全。与传统的回溯频谱分配算法相比，该算法的主要目的是在更少的频谱分配时间下增加网络吞吐量。此外，要研究所提出算法的效率，$ËØñ$考虑了各种大小，并对传统回溯算法进行了比较测量。在这里，随着网络规模的不断扩大，在算法效率上也有重要而微妙的发现。
