“…PLI-aware integer linear programming (ILP) and heuristic algorithm for both SPP and dedicated-path protection (DPP) schemes have also been implemented. Their objectives were to maximize the network resource utilization and minimize the quality of transmission (QoT), blocking probability, restoration time, and computational time 20 .…”

In future generation networks, data protection is a crucial necessity particularly when information is sent on a system. Network protection has three objectives known as discretion, reliability and accessibility. The most common procedure exploited to attain this ambition is encryption. The Generalized Multi Protocol Label Switched (GMPLS) optical networks are designed to survive Internet Protocol’s (IPʹs) unreliable delivery. In this paper, GMPLS network is proposed with random users and then the data protection algorithms have been analyzed on proposed GMPLS optical network. The various algorithms involve Rivest Shamir Adleman (RSA) algorithm and Advanced Encryption Standard (AES) algorithm. The considered algorithms are very popular but have not been implemented on GMPLS optical networks in the literature which shows the novelty of the presented work. The network performance is compared for these algorithms in terms of various parameters like blocking probability and latency. The results reveal that RSA reduces the blocking probability < 0.005 and latency < 0.007 ms. This shows that RSA gives better performance than AES algorithm and enhance the quality of service considering blocking probability, latency and overheads in GMPLS optical networks leading to enhanced data protection.

“…The efficacy of the higher spectrum is more in shared protection as compared with dedicated protection. 4,5 Considering the loss of connectivity to users sharing a single datacenter during disasters or failures, the data are cloned and periodically retained in multiple datacenters. This benefits the users in recovering the data or services from accessible data centers, irrespective of its location.…”

Efficient path selection and content availability in the optical datacenter networks are essential for business continuity. To measure quantitatively the connectivity of content and give protection to diverse type of contents, the idea of k-node content connectivity is becoming popular. However, the assignment of dedicated spectrum for each end-to-end content path consumes too many resources. In order to enhance the resource efficiency, the spectrum can be shared between end-to-content paths of various requests. The spectrum sharing minimizes the backup spectrum requirement and has been a topic of research.In this study, an innovative model, namely, end-to-end content connectivity based quasi-bipartite graphs (E-QBG) for the possible path prediction and maximum matching by Hungarian path prediction (MM-HPP) are implemented for the spectrum efficiency and the disaster resilient datacenter networks. The objective is to minimize the entire backup spectrum resource and operations path. The quasi-bipartite graph is used for the end-to-end content backup route evaluation including spectrum sharing on various links, while the Hungarian algorithm is utilized for accurate maximum matching prediction between various end-to-end route sets. We introduce the concept of maximum dissortativity path based on the weight factor. The proposed E-QBG and MM-HPP reduces spectrum consumption which guarantees survivability against multi-failure and natural disasters. This method leads to an approach for more effective utilization of the resources for end-to-end content connected elastic optical datacenter networks as compared with the existing techniques.
