Keynote David McCall, Intel
10:00 - 10:50
Standards, from IEEE, IETF, 3GPP, and Beyond Dr. János Farkas, Ericsson; Dr. Balázs Varga, Ericsson; Gino Masini, Ericsson; Anna Larmo, Ericsson  
A core set of IEEE 802.1 Time-Sensitive Networking (TSN) specifications is available for standard Ethernet and applicable to multiple verticals. In addition to the base technology, IEEE 802.1 works on TSN profiles to ensure interoperability and to facilitate the adoption of the technology. However, specifications solving larger network deployment scenarios and ensuring determinism over a wireless network providing mobility are also required to support new use cases. IETF Deterministic Networking (DetNet) provides TSN like capabilities at the Internet Protocol (IP) and Multiprotocol Label Switching (MPLS) layers to meet the former challenge. For the latter, the 3GPP defined 5G standards enable among others Ultra Reliable Low Latency Communication (URLLC) over the wireless link and features for Industrial IoT. Finally, the 5G Alliance for Connected Industries and Automation (5G-ACIA) enables network convergence by transferring 5G developments into the industrial domain, exploring new operator models, and evaluating technical, regulatory, and business aspects. 1.

Industrial TSN Profile (IEC/IEEE 60802) Ludwig Winkel, L.A.N. Winkel  
The IEEE Standards Association (IEEE-SA) and the International Electrotechnical Commission (IEC) has started a joint project IEC/IEEE 60802 Time-Sensitive Networking Profile for Industrial Automation to gather experts to define the use of IEEE 802.1 Time-Sensitive Networking (TSN) for industrial automation. This presentation provides an update versus the TSN/A 2018 presentation of the IEC/IEEE 60802 draft standard. The profile selects features, options, configurations, defaults, protocols, and procedures of bridges, end stations, and LANs to build industrial automation networks.
11:30 - 11:45
Automotive TSN Profile (IEEE 802.1DG) Harald Zweck, Infineon Technologies  
A new project has been started this year to specify the use of TSN for in-vehicle automotive networks. It is the IEEE P802.1DG TSN Profile for Automotive In-Vehicle Ethernet Communications project. Upon completion, this standard will summarize the various TSN standards that are applicable for use in vehicular Ethernet networks. It will also provide one or more profiles describing how the TSN standards can be used together in various configurations, with a goal of providing criteria useful for conformance testing and certification. This presentation will give an introduction into TSN requirements of the automotive industry, review the current status and explain how an OEM, Tier 1, or Tier 2 supplier, and others can get involved and help set the direction an progress IEEE P802.1DG.
11:45 - 12:15
TSN from an Endpoint’s Perspective – Open Solutions for an Open Standard Florian Frick, Institute for Control Engineering (ISW)  
TSN, widely accepted as the new industrial communication standard, confronts device manufacturers with the challenge of developing their next generation of products. Due to the lack of experience and reference architectures, the impact of TSN is often ambiguous. The open source initiative AccessTSN focuses on endpoints and provides answers through open solutions. This presentation gives generic insights regarding device architectures and provides specific solutions from the open source community, serving as a reference. With the goal of giving practical guidelines, discussed aspects include HW/SW, hardware abstraction, switched end points, OS-support, configuration and higher layer protocols.

Session 2
13:45 - 14:30
Keynote: In-vehicle TSN, the Backbone Network for Autonomous Driving Dr. Stefan Poledna, TTTech Auto  
Modern cars implement a variety of electronics functions which are typically packaged into so-called electric control units (ECUs). Functions need to communicate within an ECU as well as between different ECUs. Furthermore, many functions communicate with the environment that they perceive through sensors and control by actuators. The communication needs are quite diverse for different functions and, therefore, various automotive-specific network solutions have been developed over the last decades. Typically, a car will implement a multitude of those automotive network solutions, examples of common ones are: CAN, LIN, MOST, and FlexRay. More recently also Ethernet has become available for automotive usage and there are strong indications that Ethernet adoption will be fast and significant. One key driver of this development is autonomous driving. Indeed, self-driving cars drastically increase the in-vehicle communication needs which further accelerates the need for TSN to rise and shine as prime communication technology. In this talk I will discuss the overall challenges of autonomous driving and will focus on the role of TSN as communication backbone connecting different automotive domains, intra-ECU communication, as well as, TSN as sensor bus.
14:30 - 15:00
Overcoming New Security Vulnerabilities of Time-Sensitive Communications Paul Didier, Cisco  
This session will consider some of the security challenges and improvements that TSN as a new open, industrial communication technology represents. On one-hand, TSN introduces a set of new communication capabilities that alone deserve some significant security considerations. But in some ways more importantly, TSN is driving convergence required by Industrie4.0, from sensor to cloud, of previously obscure or isolated networks and communication opening up these systems to more security risks and threats. This session will consider security advantages and challenges in both perspectives.
15:00 - 15:30
TSN Network Configuration: Challenges, Models and Tools Dr. Wilfried Steiner, TTTech Industrial  
The excitement around TSN is often tempered by concerns regarding the challenges of network configuration in fields like automotive and industrial automation. The two major approaches – centralized and decentralized – each have their own merits and can be applied in different ways to solve various challenges. In this session we review these approaches and take a look at TSN configuration solutions.
15:30 - 16:00
16:00 - 16:30
Achieving High Availability with TSN Networks Stephan Kehrer, Hirschmann Automation and Control; Dr. René Hummen, Hirschmann Automation and Control  
Network convergence and real-time control based on standard Ethernet are commonly referred to as the key benefits of Time-Sensitive Networking (TSN). Another important aspect for many industrial automation networks is a new IEEE redundancy mechanism for high availability that is also provided by the TSN set of standards. In this presentation, we first outline selected existing redundancy mechanisms that are used in today’s automation networks and take a look at the redundancy features provided by the new IEEE 802.1CB standard. We then discuss benefits and differences when deploying these mechanisms in networks with real-time requirements.
16:30 - 17:00
The Unique Challenges of Testing TSN Implementations Tanuman Bhaduri, Keysight Technologies; Razvan Petre, Spirent Communications; Chair: Gary Stuebing, Cisco  
The speakers will discuss some of the unique challenges when building and implementing a TSN network.

09:00 - 09:45
Keynote 5G Networking for Industrial Applications Dr. Andreas Mueller, Robert Bosch  
While previous generations of mobile networks have mainly been designed for connecting people, 5G puts a strong focus on supporting machine-type communication in the Internet of Things. This will unlock completely new application areas in different vertical sectors, including the industrial, automotive and healthcare domains. In order to satisfy the needs of these new and often very demanding applications, 5G will offer an unprecedented performance, supporting ultra-low latencies, high reliabilities and dependable communication services. In addition to that, recently many activities have focused on supporting time-sensitive networking over 5G, such that a 5G network may appear like a TSN bridge to the outside world. This talk will give an overview of the status quo and current developments of 5G for industrial applications, with a special focus on these TSN-over-5G functionalities.

5G and TSN Integrated for Smart Factories Dr. János Farkas, Ericsson  
Industrial automation is one of the verticals that can benefit a lot from 5G by introducing proper wireless connectivity in more and more factory network segments due to the deterministic ultra-reliable low latency communication that 5G can deliver. The integration of 5G with TSN in manufacturing has a great potential to accelerate the transformation of the manufacturing industry and make smart factories more efficient and productive. We present how 5G and TSN can be integrated to provide the connectivity with the deterministic quality of service required by control application end-to-end, between end devices and cloud.
10:15 - 10:45
5G urLLC – The Path to Introduce High-Performance Wireless for Industrial Networking Dr. Masoud Sajadieh, Intel  
5G urLLC is a major extension of cellular technologies for industrial networking, characterized by real-time, and extreme reliability requirements. We provide an overview of the built-in mechanisms of 5G urLLC enabling industrial connectivity with a view to the latest enhancements in Release-16. Performance indicators will be presented along with a capability mapping to the use cases which can be enabled by the adoption of 5G urLLC in the industrial verticals. The all-important concept of interworking with industrial Ethernet protocols such as TSN will be described based on the innovations in the network architecture of 5G NR

Open Source Ecosystem for OPC UA PubSub over TSN: Scope of Project and Performance Results Carsten Emde, Open Source Automation Development Lab (OSADL)  
Following unanimous backing by several automation technology providers in favour of OPC UA PubSub via TSN to establish a unified architecture for industrial real-time communication, this initiative is designed to build an Open Source ecosystem that enables vendor independent, end-to-end interoperability from sensor to cloud. It provides industry and academia with rich generic OPC UA features interfacing to TSN. The implementation is integrated into the open62541 The goal is to provide a solution that is complete, stable and certified. This session will present the current status and performance results for hard real-time communication.
10:15 - 10:45
TSN Software Switch in Linux for Endpoints Kurt Kanzenbach, Linutronix  
The end stations in Time Sensitive Networking (TSN) enabled networks are often run by real time Linux. Many of those end points are multi port devices, so called switched end stations. We present what efforts have been made in the upstream Linux kernel in order to support these switches and how the current mainline TSN implementations, such as the Credit Based Shaper, Time Triggered Send and the Time Aware Priority Scheduler interact with the regular Linux switch configuration frameworks. Furthermore, we cover what particular parts are missing for a full TSN support today.

Implementing Audio Video Bridging on a Non-Real-Time Processor Mohan Karthik, Analog Devices  
The Ethernet AVB standard adds Quality of Service and features like time-synchronized low latency streaming services to make it possible to carry audio and video signals on a standard Ethernet line. EAVB requires a processor that has the ability to process multiple events deterministically at high speeds and with ultra-low latency. Hence this application is typically implemented on real-time processors such as ADI's Blackfin, Cortex-M or Cortex-R series of processors. This paper covers the challenges of implementing such a system on a non-deterministic processor such as Cortex-A series of processors and achieving optimal performance.

Industrial Network Segmentation with TSN Mark Hantel, Rockwell Automation  
Various technical communities have spent a significant amount of time and effort on the core TSN standards and their administration, but little time has been spent on system constructibility and modularity in the industrial space. This presentation focuses on high level concepts for segmenting and combining TSN subsystems along logical boundaries. In particular, DetNet and TSN domains will be examined at a high level as tools to combine and segment industrial TSN devices and networks along natural boundaries.
12:15 - 13:45

Redundant Interoperable TSN implementation for CNC Milling Machines Networking on the Aeronautics Advanced Manufacturing Center Alicia Alonso, System-on-Chip engineering; Michael Zapke, Xilinx  
This contribution presents a digital factory use-case for a redundant TSN implementation on a pilot section of a modern manufacturing center for the Aeronautics sector located in Europe. The set-up includes IEEE 802.1CB-2007 support from two different vendors, Xilinx for the TSN end-points devices and SoC-e for the bridges and edge-computing equipment. In this presentation, the results of the first stage of the project are presented: the behavioral of the high-level protocols over redundant Ethernet, the configuration mechanisms and models used for the configuration and a comparison to the same set-up based on HSR.
14:15 - 14:45
OPC UA Field Level Communications Initiative: Update & Roadmap Peter Lutz, OPC Foundation  
In November 2018, the OPC Foundation has launched the Field Level Communications (FLC) initiative to extend OPC UA down to the field level including TSN enabled Ethernet networks. This will advance the OPC Foundation providing vendor independent end-to-end interoperability into field level devices for all relevant industry automation use-cases. The OPC Foundation vision of becoming the worldwide industrial interoperability standard is advanced by integrating field devices and the shop floor. This presentation is a report on the ongoing work of the FLC initiative, giving insights to the status, roadmap and technical concept of OPC UA FLC.
14:45 - 15:15
15:15 - 15:45
Towards TSN + OPC UA-based Real-Time Edge Computing Dr. Florian Schreiner, Fraunhofer FOKUS / TU Berlin  
Within the multi-partner "Edge Computing + TSN + OPC UA" testbed Fraunhofer FOKUS explores and evaluates real-time OPC UA over TSN - based Edge Computing mechanisms. The testbed shows the benefits of Edge-Application over TSN Orchestration mechanisms allowing for dynamic deployment and management of real-time applications across distributed edge nodes. It shows how industrial robots can be dynamically controlled by Edge-/Software-based PLCs and how real-time applications like OPC-UA-based condition monitoring applications are dynamically deployed and managed. The presentation will highlight the benefits of Edge-based industrial automation approaches over TSN and provide major findings.
15:45 - 16:15
Workflow for Real-Time Controller and Field-Level OPC UA TSN Applications Dr. Dietmar Bruckner, B&R Industrial Automation  
Online and offline engineering of industrial Ethernet technologies poses several challenges to users. In addition, TSN and OPC UA are comparatively more complex technologies than traditional Ethernet-based field busses. The aspiration of shared and converged networks and the envisaged more complex and secure communication relations complicate the situation even more. This presentation will discuss the engineering and configuration deployment phases of OPC UA TSN applications. We will introduce possibilities for offline configuration like scheduling process data exchange and integration into IT infrastructure for address assignment and user/role management as well as options for dynamic changes to the system.
11:45 - 16:15
11:45 - 12:15
TSN and Security: Per Stream Filtering and Frame Policing Dr. Rajeev Roy, NXP  
We focus on the IEEE 802.1Qci to show how such capabilities can be used for security. Intrusion detection is related to detecting an Anomaly- anything which is not normal behaviour is an anomaly. And in detecting a Misuse-a specific pattern of activity is performed which can be seen to be suspicious. Both these aspects can be realised by the traffic filtering and performance metrics on streams. Intrusion Prevention adds a consequent action . Aspects such as preventing Denial of Service (DoS) attacks and enabling firewall applications. These can be realised by policing and time gating capabilities

TSN Implementation Challenges for Automotive Platform and related use cases for Autonomous Vehicle Architectures Ashok Kumar, AllGo Systems  
As Ethernet becomes the network of choice in Cars, TSN is adopted as the standard for transporting time critical high bandwidth sensor data and also to meet low latency requirements for Inter-ECU messaging. Consequently we see TSN getting adopted into Deeply Embedded ECUs, Sensor ECUs, Gateway ECUs and Central Compute Units. We talk about the unique challenges of implementing TSN on each of these type of ECUs. We then take a look at the different use cases for TSN in Autonomous Car Architectures and how TSN integrates with the different communication technologies like DDS, SOME/IP to achieve the final goal.
14:15 - 14:45
Performance Comparison of Using TSN Synchronous and Asynchronous Scheduling in Automotive Network Zifan Zhou, Denmark Technical University  
TSN is an attractive solution for providing deterministic service for In-Vehicle Network (IVN) built upon IEEE 802.1 architecture. Traffic scheduling and shaping in TSN aim to achieve bounded low latency, jitter and congestion loss, hereby, we mainly focus on two scheduling approaches in this paper: Time-Aware Shaper and Asynchronous Traffic Shaper, we proposed the modeling of the application of both in IVN and compare the performance under scenario with different configurations based on realistic automotive data. Giving the analysis and comparison to support to outline the TSN profile for future IVN.

15:15 - 15:45
DDS over TSN to Support NATO Generic Vehicle Architecture (NGVA) for Land Systems Dr. Armando Astarloa, System-on-Chip engineering  
In collaboration with RTI, a Connext DDS implementation over TSN is presented. The new generation of military vehicles is evolving towards standardization. As an example, NATO Generic Vehicle Architecture (NGVA) is an approach to platform design and integration. In NGVA, the information is based on DDS middleware. DDS profiles regulate the message transfer using advanced QoS parameters. However, all data types and communication layers finally rely on an Ethernet Data Link Layer. TSN in combination with DDS can ensure the deterministic of the data delivery while the overall complexity and cost of the final implementation can be drastically reduced.
15:45 - 16:15
Suitability of Time Sensitive Networking for Space Pierre-Julien Chaine, Airbus Defence & Space  
The world of embedded networks is facing a new revolution with the emergence of Time Sensitive Networking (TSN): an IEEE Ethernet technology capable of supporting both real-time and high-bandwidth traffic. TSN seems to be very appealing to the transportation industry for its adaptability, its foreseen costs, and its number of users. In parallel, in the European spacecraft industry, SAVOIR OSRA (On-Board Software Reference Architecture) aims at providing guidelines for generic satellite development. The goal of this paper is to discuss the suitability of TSN mechanisms with respect to these requirements with a qualitative study prior to a quantitative study.

Panel Discussion "Compatibility levels of TSN bridges and end-stations" Ludwig Winkel, L.A.N. Winkel; Dr. Dietmar Bruckner, B&R Industrial Automation; Chair: Heinrich Munz, Munz Consulting; Oliver Kleineberg, Hirschmann Automation and Control  
Time-Sensitive Networking (TSN) is a set of standards that can be seen as a toolbox offering different mechanisms to cater to different aspects of real-time communication over Ethernet. To allow the best possible level of interoperability for applications in the Industrial Automation (IA) space, IEC/IEEE 60802 is currently defining a profile that selects a set of mechanisms from this toolbox to be used in IA. This panel will discuss different questions around compatibility levels of TSN bridges and end-stations. Is compatibility on the feature level enough? Is it necessary to define interoperability at the application level? Is it maybe even required to enable complete interchangeability of devices? What level of interoperability needs to be defined in a broad profile and what belongs in the specifications of the different real-time ecosystems?
