With the globalisation of the multimedia entertainment industry and the popularity of streaming and content services, multicast routing is (re-)gaining interest as a bandwidth saving technique. In the 1990’s, multicast routing received a great deal

End-to-end Orchestration in Support of IIoT Applications over Optically Interconnected TSN Domains

Autor: Albert Pagès, Fernando Agraz, Salvatore Spadaro

Publikováno v: Optical Fiber Communication Conference (OFC) 2023.

We demonstrate that joint orchestration of TSN and optical network domains in support of IIoT applications reduces the TSN blocking by four orders of magnitude and the usage of high priority queues by a 28-100%.

Data Plane Technology-agnostic Control and Orchestration Architecture for Optical Disaggregated Data Centers

Autor: Fernando Agraz, Albert Pagès, Salvatore Spadaro

Publikováno v: Optical Fiber Communication Conference (OFC) 2022.

We propose a novel SDN control and orchestration architecture to provide composed IaaS over optical disaggregated data centers. We experimentally validate intent-based mechanisms that make the architecture independent from the underlying physical inf

A 4-node prototype of SDN-controlled disaggregated data-center network is experimentally demonstrated based on the nanoseconds optical switch, enabling flexible hardware resource provisioning and dynamic resource reallocation. Experimental results sh
