Field Trial of Multi-Layer Slicing Over Disaggregated Optical Networks Enabling End-to-End Crowdsourced Video Streaming

Abstract

We present a field trial of NFV Orchestration over multi-layer packet and disaggregated optical network testbed to demonstrate crowdsourced video streaming use case. We show the average service creation time is under 5 minutes, which meets the KPI as defined by 5G PPP.

NFV orchestration over disaggregated metro optical networks with end-to-end multi-layer slicing enabling crowdsourced live video streaming

“…This paper extends [8] with the following contributions. First, our work is contextualized with a literature review of related work.…”

“…To the best of our knowledge, Metro-Haul has been the only initiative to encompass from the top vertical services with two applications (video surveillance [27] and CLVS [8]) down to the underlying optical infrastructure, while covering compute and network resources with NFV and SDN principles. We mention that a similar result shown in this work related to component level setup times has been in shown in the video surveillance usecase demonstration [27].…”

“…Metro-Haul control plane consists of the Control, Orchestration and Management (COM) system [7], based on the principles of ETSI Network Function Virtualization (NFV) framework and a hierarchical SDN control plane, which facilitates the deployment of multi-layer end-toend network slices, including Virtual Network Functions (VNFs) in multiple datacenters (with multiple Virtual Infrastructure Managers (VIMs)) and simultaneously dedicates packet and optical network resources, including Layer 2 (L2) VPNs and photonic media channels. Within the context of Metro-Haul, we recently reported a field trial of NFV orchestration using COM system over multi-layer packet and disaggregated optical network testbed that demonstrated a CLVS use case with service creation time below 5 minutes for the reported NS [8].…”

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

“…Once the NS has been setup, WF2 is executed to perform commissioning testing; in this case, the focus is on RTT monitoring. The parent controller starts WF2 by requesting to measure the performance of the just-created packet circuits (11); the circuit IDs, VLAN IDs, maximum RTT, and other details are included in the request. The MDA controller requests the measurements to the active probes that use the VLAN IDs for tagging the generated Ethernet frames (12).…”

“…In this context, the H2020 METRO-HAUL project [9] has designed and built a smart optical metro infrastructure able to deliver requirements for time-critical and high-bandwidth vertical use cases, including public safety [10]. The developed solution comprises several hardware and software pieces that together form a unique networking infrastructure, including both packet and optical layers, along with an integrated Network Function Virtualization (NFV) and disaggregated network orchestration, which provides advanced connectivity and ETSI Network Services (NS) encompassing computing, storage, and networking resources [11].…”
