AI总结：
针对TSN现有研究与实际部署脱节的问题，本文提出完整的TSN生命周期架构，梳理部署挑战、工具局限与未来方向，为开发可部署的下一代TSN网络提供指导。
AI中文摘要：
时间敏感网络（TSN）为不同领域的安全关键型应用提供确定性保证和有界延迟。IEEE 802.1 TSN标准提供了一套完整的机制，用于时间同步、流量整形、调度、资源预留和可靠性。然而，在实际应用中部署TSN仍然是一项复杂的多步骤工程任务。现有研究主要集中在优化单个目标，例如提高可调度性、减少延迟、加快解决方案生成或改进性能分析。但这些经过广泛研究的解决方案能否部署到实际系统中仍未得到解答，因为这些方法中所做的假设往往与实际硬件约束不同。因此，端到端TSN部署和管理的更广泛、整体的视角仍然是一个开放的研究问题。目前，缺乏统一的视角、共识和协调一致的研究工作来关注完整的端到端TSN部署工作流程。本文对TSN部署生命周期、当前挑战、现有工具的局限性以及TSN部署和管理的未来研究方向进行了全面概述。最后，从部署的角度确定了关键的研究缺口，并为开发下一代可部署TSN网络提供了指导。
英文摘要：
Time-Sensitive Networking (TSN) provides deterministic guarantees and bounded latency for safety-critical applications across different domains. While the IEEE 802.1 TSN standards provide a comprehensive set of mechanisms for time synchronization, shaping, scheduling, resource reservation, and reliability, deploying TSN in real-world applications remains a complex, multi-step engineering task. Existing research primarily focuses on optimizing individual objectives, such as increasing schedulability, reducing latency, accelerating solution generation, or improving performance analysis. However, whether these extensively researched solutions can be deployed in real-world systems remains unanswered, as the assumptions made in these methodologies often differ from practical hardware constraints. Therefore, a broader, holistic view of end-to-end TSN deployment and management remains an open research question. Currently, there is a lack of a unified perspective, consensus, and coordinated research efforts focusing on a comprehensive end-to-end TSN deployment workflow. We present a comprehensive overview of the TSN deployment lifecycle, current challenges, limitations of existing tools, and future research directions for TSN deployment and management. Lastly, we identify key research gaps from a deployment perspective and provide guidance for the development of next-generation deployable TSN networks.
