We propose an inter-core crosstalk-aware routing, spectrum and core allocation scheme with spectrum bands and spatial Sp-Chs in multi-dimensional optical networks to get higher SE and lower XT. 15% reduction in XT is achieved.
Compared with fixed-grid optical network, flexible-grid optical network (FON) enabling technologies could provide higher spectrum efficiency and thus more capacity. With more data capacity, physical network failure (i.e., link or node) will lead to more communication disruptions, especially for multiple failures. In previous research, the protection strategies against multiple failures is mainly single-path...
To design survival datacenter networks, the concept of content connectivity, which is defined as the reachability of content from any point of a network after disaster failures, was recently proposed. To quantitatively measure content connectivity, we propose a novel concept of k-node (edge) content connectivity and apply it to optical datacenter networks. Furthermore, a novel disaster-resilient k-node...
We propose a survivable routing and resource assignment scheme with MPP and SRLG in VON to get less resources consumption and enough protection against physical failure. 29% reduction in resource consumption can be achieved.
This paper focus on the routing, modulation level and spectrum allocation (RMLSA) problem in the next generation datacentre networks, which own the advantages of both Elastic Optical Networks (EON) and Software Defined Networking (SDN). We proposes an Integer Linear Programming (ILP) model for this problem. Simulation results show the ILP model achieves an outstanding load balancing performance.
