AutoCore Launches Full-Stack TSN Solution, Empowering Next-Generation Deterministic Networking

[Nanjing, China] — In the dual wave of Industry 4.0 and Software-Defined Vehicles, high-bandwidth, low-latency, and deterministic network transmission have become the cornerstone for the evolution of various industries. Today, AutoCore, a leading global provider of intelligent mobility computing platform products and solutions, officially announced its full-stack Time-Sensitive Networking (TSN) solution for mission-critical applications. This solution delivers high-precision, low-latency, and highly reliable end-to-end deterministic communication capabilities for industry customers through deep collaboration between its "endpoint software protocol stack" and "network-side hardware infrastructure." It is particularly noteworthy that its core products have achieved ISO 26262 ASIL-D functional safety certification, providing a robust safety foundation for high-safety requirement scenarios such as automotive applications.

Leveraging its deep technical expertise, AutoCore has built a complete TSN solution, from the software protocol stack to hardware devices. This solution not only meets the stringent real-time requirements of in-vehicle networks but is also perfectly suited for industrial control and aerospace applications that demand extreme stability. The solution includes two core products:

The AutoCore TSN Fusion product series is a flexible hardware platform built on a customizable and programmable FPGA. Users can implement four distinct product functions on the same hardware platform simply by loading different firmware images, without needing to replace any physical equipment:

• TSN Switch: A full-featured TSN network switch supporting multiple 100M/1000M Ethernet communication interfaces (customizable). Its deeply integrated TSN stack provides nanosecond-level high-precision time synchronization and supports advanced network management features such as VLAN isolation, port mirroring, and dynamic MAC address learning.
• TSN TAP: A powerful testing and diagnostic tool that acts as a "diagnostician" for TSN networks. It supports multiple 100M/1000M Ethernet interfaces and can perform data pass-through and mirroring between them. It also supports fault injection and real-time monitoring of port traffic, enabling precise capture and forwarding of data packets, making it an indispensable tool for the development and verification phase.
• TSN Endpoint: An endpoint device with high-precision time synchronization capabilities, based on the gPTP protocol. It can be flexibly configured as a Master or Slave node. During development and testing, it can serve as a high-precision simulation device, significantly improving overall development efficiency.
• TSN Gateway: A feature-rich multi-protocol industrial gateway that not only supports mainstream industrial real-time Ethernet protocols such as PROFINET, EtherCAT, and EtherNet/IP, but also integrates OPC-UA data management capabilities. It features comprehensive Layer 2/Layer 3 switching functions, supports IPv4/IPv6 static routing and RIP/OSPF dynamic routing protocols, and supports ERPS ring network redundancy technology for fast self-healing in under 50ms. It also provides multiple management methods such as Console/Telnet/Web and SFTP/HTTP upgrade functions, ensuring high network availability and ease of maintenance.

Traditional network hardware often faces the dilemma of "upgrade protocol, replace device." AutoCore TSN Fusion completely resolves this limitation with the inherent programmability of FPGAs:

• Customizable Communication Interfaces: Flexibly adapts to the needs of different network topology architectures.
• Programmable Logic: Supports deep customization based on modular TSN IPs, ensuring the most precise synchronization and lowest latency at the hardware level.
• Upgradable Firmware: Easily adapts to the latest TSN protocol standards through online firmware upgrades, significantly reducing customers' long-term hardware investment and maintenance costs.

The AutoCore TSN protocol stack adapts to the standard Ethernet physical layer below and provides standard APIs for upper-layer applications above, ensuring determinism in data transmission from the source and achieving full TSN protocol stack coverage:

• IEEE 802.1AS: Ensures that the clocks of all devices in the network achieve nanosecond-level high-precision synchronization.
• IEEE 802.1Qav/Qbv: Reserves a dedicated channel for critical data streams through time-aware traffic shaping and gate control mechanisms, effectively smoothing out burst traffic.
• IEEE 802.1Qci: Implements ingress and egress traffic policing, effectively defending against network attacks and data storms.
• IEEE 802.1CB: Achieves industrial grade "zero packet loss" seamless redundancy through frame replication and elimination, ensuring uninterrupted business operations.
• IEEE 802.1Qat: Reserves bandwidth for critical data streams, guaranteeing end-to-end Quality of Service (QoS) for real-time flows.
• IEEE 802.1Qcc: Supports centralized network configuration, enabling "plug-and-play" for devices and significantly improving network deployment and operational efficiency.
• IEEE 1722: Optimized for synchronous and low-latency transmission of audio-video streams (AVTP) over TSN networks.

The AutoCore TSN software stack features excellent portability, supporting deployment on various operating systems such as QNX, Linux, Android, and Classic AUTOSAR. Whether on resource-constrained MCU-based embedded controllers or high-performance MPU/SoC-based computing units, the software provides a unified configuration interface and SDK, greatly simplifying network interconnection development between heterogeneous systems.

AutoCore's full-stack TSN solution has been successfully implemented in several key areas. In the automotive sector, the solution has been successfully applied to vehicle-wide audio bus and cockpit audio-video transmission. The TSN Switch can reserve dedicated bandwidth for audio streams, ensuring high-fidelity, uninterrupted audio transmission even in complex electromagnetic environments.

In addition to its deep roots in automotive electronics, AutoCore TSN products are also suitable for scenarios with stringent real-time and reliability requirements, such as industrial automation, rail transit, and aerospace. Whether in complex industrial sites or demanding aerospace environments, AutoCore can provide end-to-end deterministic network assurance from edge nodes to switching hardware.
