工业实时应用要求其通信网络具有鲁棒性和确定性，以便数据包以有限的延迟和抖动进行传输。IEEE时间敏感网络（TSN）任务组已经修改了IEEE 802.3以太网标准，以支持实时应用的时间触发流。然而，路由和调度问题仍然是一个悬而未决的问题。具体地，大多数现有技术的调度努力都做出某些假设，例如假设路由信息是已知的 先验地专注于调度问题或假设流的信息是预先已知的。其他避免这些假设的研究忽略了某些有价值的信息，这些信息可以用来做出更好的路由决策，比如剩余带宽。在本文中，我们首先提出了一个增量QoS感知的路径选择算法，使用QoS测量路由TSN流。然后，我们介绍了多个增量调度算法，解决上述问题，并证明他们的性能。
Industrial real-time applications demand their communication networks be robust and deterministic so that packets are delivered with bounded delay and jitter. The IEEE Time-Sensitive Networking (TSN) Task Group has amended the standards of IEEE 802.3 Ethernet to support time-triggered flows of real-time applications. However, the issues of routing and scheduling are left as open problems. Specifically, majority of the state-of-the-art scheduling efforts make certain assumptions, such as assuming that the routing information is known extit{a priori} to focus on the scheduling problem or assuming that the information of flows is known in advance. Other studies that avoided these assumptions ignore certain valuable information that could be taken advantage of to make better routing decisions, such as the residual bandwidth. In this paper, we first propose an incremental QoS-aware path selection algorithm that uses QoS measurement to route TSN flows. Then, we introduce multiple incremental scheduling algorithms that address above mentioned issues, and demonstrate their performance.
