Routing in dynamic future flexi-grid optical networks

2012 16th International Conference on Optical Network Design and Modelling (ONDM), 2012
Routing in dynamic future optical networks will depend on the underlying technology and more specifically on whether standard grid or flexi-grid technology will be used. In particular for dynamic flexi-grid networks resource allocation and routing concerns both path establishment and allocation of specific spectrum which in turn relates to the ...

Blocking performance approximation in flexi-grid networks

Optical Fiber Technology, 2016
Abstract The blocking probability to the path requests is an important issue in flexible bandwidth optical communications. In this paper, we propose a blocking probability approximation method of path requests in flexi-grid networks. It models the bundled neighboring carrier allocation with a group of birth–death processes and provides a theoretical ...

Dynamic Flexi-Grid OFDM Optical Networks

European Conference and Exhibition on Optical Communication, 2012
Dynamic flexi-grid optical networks are investigated with respect to the path establishment cost and spectrum and modulation format assignment policies. The role of spectral fragmentation with respect to the spectrum granularity and the benefit to distance adaptive OFDM flexi grid networks compared with rigid grid counterparts is established.

Virtual Network Embedding With Adaptive Modulation in Flexi-Grid Networks

Journal of Lightwave Technology, 2018
Network virtualization has been proposed as a promising method to mitigate the ossification of the Internet by allowing multiple heterogeneous virtual networks (VNs) to coexist on a shared substrate network. One of the major challenges in this method is the VN embedding (VNE) problem of how to map efficiently the virtual nodes and links onto the ...

Regenerator placement in code-rate-adaptive flexi-grid networks

2014 The European Conference on Optical Communication (ECOC), 2014
The regenerator placement is optimized in a code-rate-adaptive optical network with flexible grid and guaranteed QoT, using a genetic algorithm approach. Results demonstrate that code rate adaptation reduces both the number of regenerators and the spectrum utilization.

Dynamic Operation of Flexi-Grid OFDM-based Networks

Optical Fiber Communication Conference, 2012
Routing in dynamic OFDM-based optical networks by simultaneous optimization of allocated spectrum and transponder reach is proven beneficial when flexi-grid technology is used regarding blocking performance and spectral efficiency when compared to standard-grid counterpart.

Virtual network embedding in flexi-grid optical networks

2017 IEEE 17th International Conference on Communication Technology (ICCT), 2017
Network virtualization technology makes multiple virtual networks (VNs) that provide heterogeneous services share the same substrate network. Virtual network embedding (VNE) maps VNs to the substrate network, and allocates network resources. In this paper, we provide VNE algorithms for efficient management of flexi-grid networks, where virtual link ...
