Demonstration of latency-aware 5G network slicing on optical metro networks

Abstract

The H2020 METRO-HAUL European project has architected a latency-aware, cost-effective, agile, and programmable optical metro network. This includes the design of semi-disaggregated metro nodes with compute and storage capabilities, which interface effectively with both 5G access and multi-Tbit/s elastic optical networks in the core. In this paper, we report the automated deployment of 5G services, in particular, a public safety video surveillance use case employing low-latency object detection and tracking using on-camera and on-the-edge analytics. The demonstration features flexible deployment of network slice instances, implemented in terms of ETSI NFV Network Services. We summarize the key findings in a detailed analysis of end-to-end quality of service, service setup time, and soft-failure detection time. The results show that the round-trip-time over an 80 km link is under 800 μs and the service deployment time under 180 seconds.

TAPI-based Telemetry Streaming in Multi-domain Optical Transport Network

“…In this work, we present a partially disaggregated network with domain controllers managed by a multi-domain controller using ONF-TAPI for control and monitoring capabilities. The optical devices in the data plane are deployed as real entities in the Fraunhofer HHI testbed, Berlin [6] with each entity mounted to the respective domain controller. With data from multiple sources along the service path, data analytics is essential to summarise the data and derive insights from it.…”

Detection Collision Flows in SDN Based 5G Using Machine Learning Algorithms

“…In contrast to the constraints of conventional networking topologies, the SDN [22] concept has arisen. On the other hand, the traffic created by 5G [23] networks is heterogeneous. Video broadcasting, online gaming, cloud storage, and other classes demand dependable, consistent network services with rigorous QoS [24] standards.…”

Deep learning-based real-time analysis of lightpath optical constellations [Invited]

“…The new type of services enabled by 5G and beyond technologies require to be supported by a programmable autonomous optical network infrastructure [1,2]. Such new types of services usually require high network performance in terms of bitrate and latency [3], which, together with their dynamicity, makes decentralization and softwarization essential features of that infrastructure.…”
