Multipath provisioning is a survivable and resource efficient solution against increasing link failures caused by natural or man-made disasters in elastic optical datacenter networks (EODNs). Nevertheless, the conventional multipath provisioning scheme is designed only for connecting a specific node pair. Also, it is obvious that the number of node-disjoint paths between any two nodes is restricted...
We propose a survivable multipath routing and spectrum allocation with content connectivity scheme in OFDM-based elastic datacenter networks. This scheme achieves better performance in resource utilization compared with traditional protection schemes.
This paper addresses the RMLSA problem for end-to-content paths while satisfying k-node (edge) content connectivity requirement in elastic optical datacenter networks. Two distance-adaptive SWP-based RMLSA algorithms are proposed to improve the spectrum efficiency.
Disaster, natural or man-made, is the main threaten of survivability and reliability of networks. The development of content connectivity provides a new way of protection against disaster to ensure the reliability of network service/content. This paper focuses on shared backup path protection based on content connectivity against disaster in the context of elastic optical datacenter networks. In this...
