Abstract:

To extend industrial Ethernet to guarantee real-time quality-of-service (QoS), the IEEE 802.1 Time-Sensitive Networking (TSN) task group has been developing a series of specifications, including the flow control series, of which Credit-Based Shaping (CBS) and Asynchronous Traffic Shaping (ATS) were defined in IEEE 802.1 Qav standard and IEEE 802.1 Qcr draft respectively. While CBS is a per-class scheduling strategy, ATS is a per-flow scheduling. To analyze performance of these flow control strategies, comparison among CBS, ATS and Strict Priority Queuing (SPQ) is performed using a suite of self-developed models. Models were implemented and operated in the OMNeT++ simulation platform. Moreover, CBS and ATS are implied in different network load. And the results show that ATS flow control strategy can provide better real time performance guarantee for aperiodic traffics than CBS in heavy network load.
