This demonstration shows how the 5G-TRANSFORMER platform, and more specifically the vertical slicer, is capable of arbitrating vertical services. In this context, arbitration refers to handling the various services of a given vertical customer according to their SLA requirements, service priorities, and resource budget available to the vertical. In this demo, a low priority video service of the automotive vertical is terminated when a high-priority intersection collision avoidance service needs to be instantiated and there are not enough resources allowing all services to be run in parallel. All these services are deployed with the help of the 5G-TRANSFORMER platform in a multi-PoP scenario, with PoPs in Barcelona (Spain), Turin (Italy), and Pisa (Italy), featuring a high variety of transport and computing technologies.

HURRA! Human-Readable Router Anomaly Detection

Jose M Navarro and Dario Rossi (Huawei Technologies Co. Ltd.)

Automated troubleshooting tools must be based on solid and principled algorithms to be useful. However, these tools need to be easily accessible for non-experts, thus requiring to also be usable. This demo combines both requirements by combining an anomaly detection engine inspired by Auto-ML principles, that combines multiple methods to find robust solutions, with automated ranking of results to provide an intuitive interface that is remindful of a search engine. The net result is that HURRA! simplifies as much as possible human operators interaction while providing them with the most useful results first. In the demo, we contrast manual labeling of individual features gathered from human operators from real troubleshooting tickets with results returned by the engine - showing an empirically good match at a fraction of the human labor.

One of the key challenges in developing 5G/6G is to offer improved vertical service support providing enlarged service flexibility, coverage and connectivity while enhancing the business relations among different stakeholders. To address this challenge, Network Service Federation (NSF) is a required feature to enable the deployment and the management of vertical services that may span multiple provider domains owned by different operators and/or service providers. In this demonstration, we show our proposed NSF solution to dynamically deploy an eHealth network service across multiple provider domains at different locations.

In telecommunications, fault management is critical to improve network availability and user experience.To enhance reliability of their networks, operators require tools to quickly understand the cause of an outage. In particular, logs of alarms keep track of failures arising in their infrastructures. Due to the increasing size of networks and to the high diversity of technologies, these files may be verbose and noisy. That is why analyzing a log is often complex, hence delaying recovery and then degrading network availability. This demo presents a tool suite dedicated to log analysis. Our methodology is illustrated through the processing of a real alarm log issued from a 4G network. First, one can simplify the log by discarding irrelevant alarms and by clustering co-occurrent ones. Then, the underlying graph structure, called DIG-DAG, can store causal patterns by processing the input log online. Hence, experts can query the DIG-DAG to retrieve small and interpretable patterns.

Hologram video is expected to be the next generation video by providing immersive viewing experiences with 6 degrees of freedom, and a typical application of 6G cellular networks. How to efficiently transmit hologram video is one fundamental research issue to promote its applications. As one of the most popular ways to represent hologram, point cloud video draws more and more attentions. Point cloud video streaming faces many challenges due to large source video rate and high encoding/decoding complexity. To this end, we propose a novel DASH-based point cloud video streaming system: Narwhal, which aims to maximize the user's viewing experiences by efficiently allocating the computational and communication resources. We prototype this system and verify its performance over state-of-the-art wireless networks.

iCrutch: A Smartphone-based Intelligent Crutch for Smart Home Applications

Ke Lin, Siyao Cheng and Jianzhong Li (Harbin Institute of Technology, China)

As the rapid development of smart home applications, they bring us much more convenience to operate smart lights, room heaters etc., directly. However, it is still hard for the elderly or someone with leg problems to operate the above things because the movement of them is dependent on a pair of crutches so that their hands are not always available while using crutches. Therefore, if the elderly or someone with leg problems can control the devices directly with crutches, it will become more comfortable and convenient for them to live in the smart houses. Due to such motivation, we propose iCrutch in this demo. By bidding the user's obsolescent smartphone on the currently-used crutch, iCrutch can recognize the user's actions and send controlling commands to the smart home actuators for further response. Unlike remote controllers, our iCrutch permits the user to operate without leaving his/her hands from the crutches. Meanwhile, iCrutch almost does not introduce extra cost since the obsolescent smartphone and the current crutch are made full use of. The expense of our system is noticeably reduced compared with embedding a smart system into the crutch.

This Demo showcased the Application-aware IPv6 Networking (APN6) framework, which takes advantage of the programmable space in the IPv6/SRv6 (Segment Routing on the IPv6 data plane) encapsulations to convey application characteristics information into the network and make the network aware of applications in order to guarantee their SLA. APN6 is able to resolve the drawbacks and challenges of the traditional application awareness mechanisms in the network. By utilizing the real-time network performance monitoring and measurement enabled by Intelligent Flow Information Telemetry (iFIT) and further enhancing it to make it application-aware, we showed that the VIP application's flow can be automatically adjusted away from the path with degrading performance to the one that has good quality. Furthermore, the flexible application-aware SFC stitching application-aware Value Added Service (VAS) together with the network nodes/routers is also demonstrated.

Non-orthogonal multiple access (NOMA) is a promising technique for improving the performance of Wi-Fi networks. With NOMA, a Wi-Fi access point may simultaneously transmit several flows. However, the ability of the NOMA devices to recover their frames depends on how the signals are multiplexed. In this demo, we extend our previously designed NOMA Wi-Fi prototype to enable constellation rotation. This feature can combat the phase noise, a detrimental effect for NOMA signals. We experimentally study constellation rotation and prove that it makes NOMA signal reception more robust compared to traditional NOMA.

The time-varying properties of the wireless channel are a powerful source of information that can complement and enhance traditional security mechanisms. Therefore, we propose a cross-layer authentication mechanism that combines physical layer channel information and traditional authentication mechanism in LTE. To verify the feasibility of the proposed mechanism, we build a cross-layer authentication system that extracts the phase shift information of a typical UE and use the ensemble learning method to train the fingerprint map based on OAI LTE. Experimental results show that our cross-layer authentication mechanism can effectively prompt the security of LTE system.

Industrial Internet of Things (IoT) calls for not only highly reliable, quasi-deterministic and low-power networks, but also for more flexible and programmable networks to cope with operator's dynamics demands. Software Defined Networking (SDN) offers the high levels of flexibility and programmability that traditional distributed protocols cannot offer. In between a fully centralized SDN-on-IoT management solution and a traditional fully distributed one, Whisper stands out as a trade-off solution that has the robustness, scalability and low-overhead of distributed solutions and the flexibility and programmability of centralized ones. In this demo we present a hands-on experience of how Whisper can be jointly used with traditional SDN solutions, such as ONOS, in order to extend the already existing network programmability in wired domains to 6TiSCH-based Industrial IoT segments. We deploy and test such architecture in real-world large-scale testbeds and demonstrate to be feasible and beneficial to provide an efficient and programmable end-to-end control over a heterogeneous network.

The network edge presses an urgent need for efficient network management and orchestration (MANO), in order to efficiently cope with the wide heterogeneity in services and resources, while providing a low-latency for the hosted services. Based on ETSI standardization, the MEC platform can be managed and orchestrated by NFV MANO components. In this demo, we show how to measure the impact of the Virtualized Infrastructure Manager (VIM), which is a component of the NFV MANO, on the performance of the MANO system. In our testbed-based experimentation, we evaluated the performance in terms of time needed for a MANO system to instantiate/terminate a network service on top of the MEC platform. Open Source MANO (OSM) and Open Baton are used as MANO entities, while for the VIM environments we investigated the impact of OpenStack and Amazon Web Services (AWS) on the above-mentioned OSM, and the impact of OpenStack and Docker on Open Baton.

UAV-based physical sensing has become a reliable sensing instrument that utilizes physical sensors installed on drones. However, various limitations (e.g. requiring manual input and finite battery life) hinder their mass adoption in disaster response applications. In contrast, social sensing is protruding as a new sensing paradigm that leverages “human sensors" to collectively obtain information about the physical world. In this demo, we compare and contrast several UAV-based sensing solutions, social sensing solutions, and hybrid solutions utilizing both social sensing and UAVs in disaster response applications. We evaluate the systems on a real-world disaster response case study which exhibits the detection effectiveness and swiftness of the integrated social and drone based framework, namely SocialDrone. The demonstrated framework highlights the importance of a closed-loop integrated social-physical sensing system and presents significant performance gains in terms of accuracy and deadline hit rate.
