Hybrid Optimized Approaches for Routing and Resource Reservation Protocols in Optical Networks

open access: yesIEEE Photonics Journal, 2021
We have proposed hybrid approaches to solve dynamic provisioning problems in fixed-grid and elastic optical networks (EON). The proposed approaches use the information from the optimization models, which normally are used to solve static problems, to ...

Routing in cognitive radio networks with full-duplex capability under dynamically varying spectrum availability

open access: yesICT Express, 2021
This paper proposes a routing scheme for full-duplex-(FD)-based multi-hop CRNs that attempts to maximize the packet-delivery-ratio between any source–destination pair by being aware of the time-varying nature of spectrum-availability of the operating ...

Wide-Sense Nonblocking Converting-Converting Networks with Multirate Connections

open access: yesSensors, 2022
In this paper, we consider a two-stage converting-converting (CC) switching network. This structure can be used, for instance, in switches of elastic optical networks (EONs) or in time-division switches.

Latency-Aware Routing and Spectrum Assignment with Deep Reinforcement Learning

open access: yes2022 18th International Conference on the Design of Reliable Communication Networks (DRCN), 2022
This paper evaluates different aspects of the performance of a solution for routing and spectrum allocation in elastic optical networks. The evaluation includes the experimentation under different traffic loads and the use of a previously trained deep reinforcement learning (DRL) agent. The obtained results show that the DRL agent further outperforms a

A Single–Multi-Path Combinatorial RMSA Algorithm with Least Resource Consumption in Semi-Filterless Optical Networks

open access: yesPhotonics, 2023
Filterless optical networks (FONs) have become a cost-effective solution for optical network deployment due to their low-cost characteristics. However, eliminating active switching elements causes signals to propagate over unintended links, wasting ...
