摘要

随着数据流量的规模和重要性不断增长,生存能力在管理高速网络中变得越来越重要。此外,光纤网络中可用的更高数据速率加剧了故障的影响。本研究的目的是优化生存性方法,以解决一种技术中多链路和节点故障的容量效率和快速恢复时间问题。大多数研究工作只在单个失败中解决了这两个限制中的一个。本研究旨在开发和实施一种称为Multi-Suv系统模型的新集成方法,以解决光网络链路和节点中的多重故障。进行了实验,以证明系统模型能够根据绝对数字的基本尺度中定义的重要性强度来识别故障的性质(Saaty, 1980);因此,通知恢复或保护的路径,以解决链路和节点故障。对该模型进行了实验仿真,结果表明该模型具有减少网络资源使用、快速恢复时间、保证可用性和可靠性的优点。这项研究的社会经济价值将减少网络基础设施和设施的CAPEX资本投资,以及ICT行业服务交付的运营成本OPEX,从而提高网络和服务提供商的盈利能力。& # x0D;关键词:WDM(波分复用),OXADM(光交叉添加);Drop Multiplexer)、Intelli-MUX (Intelligent Multiplexer)、DeMux (de复用器)、OPSS(光交换系统)、OPXC(光交叉连接)、CAPEX(资本支出)、OPEX(运营支出)、OPM(意见性能矩阵)。

NEW INSIGHTS ON SURVIVABILITY IN MULTIPLE LINK AND NODE FAILURES OF OPTICAL NETWORKS
Survivability becomes increasingly critical in managing high-speed networks as data traffic continues to grow in both size and importance. In addition, the impact of failures is exacerbated by the higher data rates available in optical networks. The purpose of this study is to optimize the survivability approach to address the problem of capacity efficiency and fast recovery time of multiple link and node failures in one technique. Most research works done had only addressed either of these constraints in a single failure. This research intends to develop and implement a new integrated approach called Multi-Suv system model to address multiple failures in links and nodes of an optical network. Experiments was conducted to demonstrate the ability of the system model to identify the nature of failure based on the intensity of importance as defined in the fundamental scale of absolute numbers (Saaty, 1980); thus, inform on the path of restoration or protection to address the link and node failures. Following experimental simulations done on the model, the results shows that there are benefits amongst are reduced network resource usage, speedy recovery time, guaranteed availability and quality of reliability. The socio-economic value of this research will reduce the CAPEX capital investment of network infrastructures and facilities and OPEX the operational costs of service delivery of the ICT industry thereby increasing the profitability of the network and service providers.
