Abstract

The audio-video bridging (AVB) technology has been standardized by IEEE to deliver high-quality audio/video in real time over an Ethernet network. The IEEE AVB Ethernet standard includes protocols to synchronize time, set up standards for stream reservation, and schedule standards for forwarding and queuing, among others. However, AVB is difficult to apply to industrial networks such as industrial automation and automobiles due to lack of consideration for control data that must ensure transmission time. To solve this issue, IEEE proposes the 802.1 time-sensitive network standard, and various studies are being conducted with regard to related applications. In this study, based on the structure of the existing IEEE 802.1Qav protocol, the time-determined forwarding and queuing functions designed using the time-aware shaper, priority queuing, and credit-based shaper algorithms are described. TC275 (Infineon) was used for functional implementation, and VN5620 (Vector) was used for data monitoring. Through the experimental process in the simulation environment, it was confirmed that the TAS algorithm transmits control data at intervals of 200ms and 500ms.
