Evaluating availability of optical networks based on self-healing network function programmable ROADMs
TL;DR: Self-healing capabilities of AoD nodes arising from their flexibility and ability to employ idle components for failure recovery are demonstrated and evaluated and a routing algorithm which obtains a targeted portion of lightpaths switched at the fiber level, called the enforced FS (EFS) algorithm is proposed.
Proceedings ArticleDOI
SDN-enabled programmable optical packet/circuit switched intra data centre network
Bingli Guo,Shuping Peng,Christopher L. Jackson,Yan Yan,Y. Shu,Wang Miao,Hjs Harm Dorren,Nicola Calabretta,Fernando Agraz,Jordi Perello,Salvatore Spadaro,Giacomo Bernini,R. Monno,N. Ciulli,Reza Nejabati,Georgios Zervas,Dimitra Simeonidou +16 more
TL;DR: An SDN-enabled optical DCN leveraging AoD, OPS, FPGA-based ToR with extended OpenDayLight controller and extended OF protocol is demonstrated, demonstrating application-aware OCS/OPS connection provisioning, end-to-end connections latency, and OCS-OPS switchover.
Proceedings ArticleDOI

TL;DR: This paper reports on the general architecture for a sliceable bandwidth variable transponder as discussed within the IDEALIST European project and some driving ideas on a possible modular implementation are shown.
Proceedings Article
Filterless networks based on optical white boxes and SDM
TL;DR: This work proposes an agile and programmable multicore fiber (MCF)-based filterless network that exploits the flexibility offered by spatial domain multiplexing andprogrammable optical switches to eliminate filterless networks.
