Network Aware Compute and Memory Allocation in Optically Composable Data Centres with Deep Reinforcement Learning and Graph Neural Networks
Zacharaya Shabka, Georgios Zervas
Resource-disaggregated data centre architectures promise a means of pooling resources remotely within data centres, allowing for both more flexibility and resource efficiency under…
One-shot, Offline and Production-Scalable PID Optimisation with Deep Reinforcement Learning
Zacharaya Shabka, Michael Enrico, Nick Parsons +1
Proportional-integral-derivative (PID) control underlies more than of automated industrial processes. Controlling these processes effectively with respect to some specified…
Random Walk for modelling Multi Core Fiber cross-talk and step distribution characterisation
Alessandro Ottino, Hui Yuan, Yunnuo Xu +2
A novel random walk based model for inter-core cross-talk (IC-XT) characterization of multi-core fibres capable of accurately representing both time-domain distribution and frequen…
On the Relationship Between Network Topology and Throughput in Mesh Optical Networks
Daniel Semrau, Shahzaib Durrani, Georgios Zervas +2
The relationship between topology and network throughput of arbitrarily-connected mesh networks is studied. Taking into account nonlinear channel properties, it is shown that throu…
Experimental Analysis on Variations and Accuracy of Crosstalk in Trench-Assisted Multi-core Fibers
Hui Yuan, Alessandro Ottino, Yunnuo Xu +8
Space division multiplexing using multi-core fiber (MCF) is a promising solution to cope with the capacity crunch in standard single-mode fiber based optical communication systems.…
SWIFT: Scalable Ultra-Wideband Sub-Nanosecond Wavelength Switching for Data Centre Networks
Thomas Gerard, Christopher Parsonson, Zacharaya Shabka +3
We propose a time-multiplexed DS-DBR/SOA-gated system to deliver low-power fast tuning across S-/C-/L-bands. Sub-ns switching is demonstrated, supporting 12250 GHz channels…
