“…The performance comparison between WDM, BDM and SDM are out of the scope of this paper. For interested readers, please refer to [8,12] In [13] we presented the first TAPI-enabled SDN control architecture for partially disaggregated multi-domain (OLS) and multi-layer (WDM over SDM) optical networks. The target scenario involved multiple WDM OLS domains and SDM OLS domains (i.e., SCN), as well as multiple transponders.…”

Network operators are facing a critical issue on their optical transport networks to deploy 5G+ and IoT services. They need to address the capacity increase by a factor of 10, while keeping a similar cost per user. Over the last years, network operators are working on the optical disaggregated approach with great interest for achieving the required efficiency and cost reduction. In particular, partially disaggregated optical networks allows to decouple the transponders from the transport system (known as Open Line System) that are provided by different vendors. On the other hand, Spatial Division Multiplexing (SDM) has been proposed as the key technology to overcome the capacity crunch that the optical standard singlemode fibers are facing to support the forecasted 10x growth. Spatial core switching is gaining interest because it enables to deploy SDM networks to bypass the overloaded Wavelength Division Multiplexing (WDM) networks, by provisioning spatial media channels between WDM nodes. This paper presents the first experimental demonstration of TAPI-enabled SDN control architecture for partially disaggregated multi-domain and multi-layer (WDM over SDM) optical networks.

Int5Gent targets the integration of innovative data plane technology building blocks under a flexible 5G network resource, slice and application orchestration framework, providing a complete 5G system platform for the validation of advance 5G services and Internet of Things (IoT) solutions. The platform can act as the enabler for the transition beyond the current 5G networking capabilities allowing novel and state-ofthe-art data transport and edge processing solutions to be evaluated under a cutting-edge network orchestration framework, with intelligent service allocation and management capabilities. A sample of the envisioned technologies include: flexible multi-Radio Access Technology (multi-RAT) baseband signal processing, millimeter Wave (mmWave)technology solutions at 60GHz and 150GHz bands, hardware-based edge processor with Time Sensitive Networking (TSN), Graphical Processing Unit (GPU)processing capabilities, and elastic Software Defined Networking (SDN)-based photonic data transport. The integration of the technology blocks is performed as part of an overall architecture that promotes edge processing and is orchestrated by a Network Function Virtualization Orchestrator (NFVO) compatible framework with edge node extensions at the network layer and an overlay vertical services application orchestrator at the user plane layer.
