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.
