Timing Analysis for Optimal Points in Credit-Based Shaper of Time Sensitive Network

TSN or Time-Sensitive Network is an aggregation of standards that can include the Ethernet extension to support the real-time application while preserving the safety-critical distribution with the hardware. To improve real-time guarantees establishes multiple shaping such as Credit-Based Shaping (CBS), Asynchronous Traffic Shaping (ATS), Burst Limiting Shaping (BLS) and scheduling processes like Time Aware Shaping (TAS) and various traffic are incorporated. In industrial applications, CBS and TAS combination are widely used. Due to increase of number of traffic in modern industries, control data traffic (CDT), are frequently transfer of the system as a consequence AVB credit are freeze very often and behavior of credit of AVB and timing are continuous changing. Analyzing of the behavior of AVB credit for different timing conditions, it can be predicted total traffic condition of different flows and optimistic shaping mechanism of CBS can enhance quality of service. Several optimal cases have been studied.
