Abstract

Semi-filterless optical network (semi-FON) is a promising scheme for upgrading the aggregation networks and anycast service provisioning problem is one of the key issues in semi-FON. In this paper, we investigate this problem and propose three anycast service provisioning algorithms, namely IT resource balancing (ITRB) algorithm, spectrum resource balancing (SRB) algorithm, and spectrum and IT resource balancing (SnITRB) algorithm. The algorithms balance the use of IT or/and spectrum resources in different datacenters and links, in order to achieve the goal of serving more anycast requests. Simulation results show that, the proposed algorithms can reduce blocking probability of anycast requests to a certain extent, while the SnITRB algorithm has the best performance. Quantitatively, relative to the baseline, the SnITRB algorithm achieves an improvement in blocking probability ranging from 84% to 100% when the IT resources are sufficient, and up to 59% when the IT resources are insufficient.

频谱与IT资源均衡的半无滤波器光网络中任意播业务发放

半无滤波器光网络（semi-FON）是一种很有前途的汇聚网络升级方案，而任意播业务的提供问题是半无滤波器光网络的关键问题之一。本文对该问题进行了研究，提出了三种任意播业务提供算法，即IT资源平衡（ITRB）算法、频谱资源平衡（SRB）算法和频谱与IT资源平衡（SnITRB）算法。这些算法平衡了不同数据中心和链路中IT或/和频谱资源的使用，以实现服务更多任意播请求的目标。仿真结果表明，本文提出的算法可以在一定程度上降低任播请求的阻塞概率，其中SnITRB算法的性能最好。在数量上，相对于基线，SnITRB算法在IT资源充足时，阻塞概率提高了84% ~ 100%，在IT资源不足时，阻塞概率提高了59%。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
