Optimizing Multimedia Transmission in Time-Sensitive Networking with Delay-Based Routing for Cyber-Physical Systems
摘要
Multimedia traffic is critical to Cyber-Physical Systems (CPS) because it uses various types of media (such as audio, video, and images) to provide more contextual and correct information. Therefore, CPS operators are allowed to make decisions. Jitter and delay are important for multimedia traffic because they have a major impact on transmission quality. TSN (Time-Sensitive Networking) is an IEEE standard for deterministic real-time communication over Ethernet networks. However, current TSN research focuses on scheduling synthesis without taking into account overall routing planning. We proposed using the delay-based routing (DBR) technique to find a feasible path with a bounded jitter for multimedia streams in the TSN environment. Experimental results show that DBR is appropriate for mixed time-triggered (TT) and audio-video-bridging (AVB) streams with bound end-to-end latency and reduced maximum jitter.
