IOWN Global Forum Recognized PoCs demonstrate the viability, value, and performance of IOWN based technologies in building a connected and sustainable world. Each PoC is developed outside of the IOWN Global Forum and undergoes a rigorous evaluation by subject matter experts before ultimately being approved by the Board of Directors as an IOWN Global Forum Recognized PoC. Recognized PoCs receive their designation for having been developed consistent with one or more PoC References published by the Forum.
About the PoC Program
The Proof of Concept (PoC) Program is an external activity designed to encourage implementations of IOWN technologies. PoC teams develop PoCs outside of the Forum and submit PoC Reports to the Forum to achieve the IOWN Global Forum Recognized PoC designation and influence internal Forum activities such as the development of technical documents and software. For a list of published PoC References visit the Forum Technology webpage. Further PoC References will be continuously published based on the latest technical documents covering domain-specific references, complementary platforms, and the foundational infrastructure.

IOWN Data Hub PoC Reference V1.0: Senario1 (Frontend-to-Data Service PUT Communication Acceleration with Open APN) was conducted to test PUT capabilities on high-performance IBM Power. We tested the capability of PUT using Kafka (IBM Event Streams) and Open APN on a high-performance IBM Power Server. Network variations were 1GE, Open APN (100GE), and Non-APN (100GE on LAN). This POC assumes inter-application communication between (1) edge and central clouds, (2) between edge clouds, and (3) between central clouds, and uses APNs and middleware to implement high-level communication protocols between applications. We considered ways to optimize software, network, and hardware configurations to maintain high availability, high scalability, and high flexibility. In particular, for inter-application integration, we will focus on Kafka (IBM Event Streams) and Open APN to optimize functionality.

NTT and Oracle have conducted the PoC with regard to IOWN Data Hub concept. The objective of the PoC was to explore the future of distributed data processing, including Multi-Access Edge (MEC), using APN. As a result, basic knowledge has been acquired through this PoC on 1) how to efficiently transfer data to the Central Cloud that has been initially received and pre-processed at MEC, 2) how to maintain the DB performance while replicating data between multiple locations, and 3) the technical elements for efficient data processing at MEC. These findings will be the foundation for opening up the era of distributed data processing envisioned by IOWN Global Forum.

RDMA is a useful technology for high speed and low latency. Generally, RDMA is developed for relatively short distance communication, but we conduct long distance communication over APN using RDMA in PoC. We report the results of the objectives, to determine the dependence of maximum bandwidth on distance of the RDMA-over-Open-APN, stated in the PoC reference. We prepared configuration which meets key requirements and conducted step-by-step performance test. As a result, we obtained high performance and confirmed that we achieved objectives.

The multiple number of mobile fronthaul solutions were implemented to meet the requirement of the emerging disaggregated radio access network for 5G and beyond. The intention of this Proof of Concept (PoC) is to demonstrate fixed WDM fronthaul solutions that currently work in SK Telecom’s 5G network and to verify their performance in terms of maximum cell throughput, transport latency, and power consumption. One aspect of this PoC is the benchmark that the power consumption of All-photonics fronthaul system is less than that of semi-active fronthaul system. We want to figure out how much the difference of power consumptions is. This PoC report describes the architecture of fixed WDM network, as an example of the future mobile fronthaul solutions for beyond 5G or 6G. The measurement methods and results interworking with Nokia 5G system are also explained.

In the Area Management Security Use Case of IOWN GF, the energy efficiency of computing infrastructure needs to be drastically improved for processing data in real-time image analysis of video streams from a massive number of surveillance cameras. As a solution to this problem, we conducted this PoC employing IOWN GF architecture such as Open all-photonics network (APN), data-centric infrastructure (DCI) with data-plane acceleration (DPA). That is, this PoC demonstrates the heterogeneous computing by Kubernetes (OpenShift container platform) enabling x86 Logical Service Node with x86 CPU, smartNIC, data processing unit (DPU), and GPU for the AI inference of video streams. In addition, performance evaluations have been conducted through Open APN to show that the use case can be achieved on geographically-distributed computing infrastructure without bottlenecks. As most IOWN GF members do not yet have a composable disaggregated infrastructure (CDI) system which is under discussion as a part of DCI Cluster in DCI-TF, this PoC report might help all IOWN GF members to see how the PoC can be started with a commercial off-the-shelf (COTS) server instead of a DCI system with CDI features. This also helps DCI-TF to learn about what type of composable Peripheral Component Interconnect Express (PCIe) device IOWN GF members are trying to use for the purpose of the use case reference implementation model (RIM) PoC.

As Step 1 of the PoC, we measured the level at which O-RAN KPIs can be met when an APN device is inserted into the mobile fronthaul between RU and DU.
We demonstrated that the application of the APN solution to the mobile fronthaul is viable as a business use case.
Based on the results obtained from this PoC, when inserting Nokia’s APN device in the mobile fronthaul section in the network, it added an additional latency of approximately 10μs compared to the latency without the insertion. Assuming a latency of 5μs per 1km for the fiber optic distance, C-RAN implementation over a broad area of up to 28km is still possible, even though the total maximum fiber length is reduced by 2km. During the POC verification, we confirmed that call connections and throughput were possible without issue for distances of up to 25km between APN-G and a combination of APN-G or APN-I extensions. The resulting latency was 132.647μs, leaving a margin of 17.353μs up to 150μs, which indicates that a distance extension of up to 3km based on fiber distance is possible.

This document is a report on the results of the implementation of a PoC listed in the PoC reference document “Open APN Architecture PoC Document”, which is being discussed in the OAF TF of the IONW Global Forum. The PoC described in this report is based on the section 2.5 “Connection case of fiber sensing with APNG” in the reference document “Open APN Architecture PoC Reference“. For the fiber sensing architecture for implementing fiber sensing in APN defined by “IOWN Global Forum Fiber Sensing for Open APN”, we use of APN-G as a switching function of a sensing fiber where APN-G is prepared in APN and shared with communication service. This PoC will verify if this APN-G can be used for fiber sensing. This report shows the PoC of some possible connection between APN-G and fiber sensing. However, the specifications of APN as a whole, including APN-G, are still under discussion, and the implementation model of fiber sensing will be updated as it evolves, and multiple technical PoCs will likely be required.

This PoC project is a single-phase project. A PoC demonstration was conducted at the event described in Section 3. The performance measurements and evaluations were conducted using the demonstration system described in Section 4. Section 4 also describes the relationships to the PoC Reference [1]. Although it is intended to be a single-phase project, as there might be some successor PoC projects in future, some additional performance evaluations would be considered using the PoC system in this PoC.

In the Area Management Security Use Case of IOWN GF, it is required to dramatically improve the energy efficiency of the computing infrastructure for processing data in real-time image analysis of video streams from massive security cameras. As a solution to this problem, IOWN GF provides a DCI (Data-Centric Infrastructure) Functional Architecture document [1] that proposes the concept of “heterogeneous and disaggregated computing” in which a logical service node (LSN) is formed by combining various computing devices flexibly and optimally according to the workload. Also, the Reference Implementation Model (RIM) for the Area Management Security Use Case document [2] shows how to utilize in DCI in the same use case. This PoC report describes, as an example of DCI implementation, a demonstration system employing an LSN configuration that combines multiple types of accelerators, such as GPU and FPGA, and shows the effects of applying the system to part of the CSP Area Management Security use cases.
