Improve Service Curve Using Non-overlapped Gate in Time Sensitive Network Switch

When a Time-Sensitive Network, comes to networking, TSN is an assemblage of standards that may incorporate the Ethernet extension to enable real-time applications while maintaining the safety-critical distribution with the hardware and software. Multiple shaping processes, such as Credit-Based Shaping (CBS), Asynchronous Traffic Shaping (ATS), Burst Limiting Shaping (BLS), and scheduling procedures, such as Time Aware Shaping (TAS), are used to enhance real-time guarantees. Different traffic types are also included in the shaping mechanism. It is very common to see the combination of CBS and TAS in industrial applications. CBS and TAS combination shaping adopt gate control list (GCL), which have periodic scheduling gate. However, due to the increased number of traffic, the frequency overlaps with different traffic gates, and for this reason, congestion of data in different traffic gates happens quite often. This paper proposes a theoretical approach that does not include overlapping gates; therefore, the service in the data traffic can be improved significantly. Integer Linear Programming has been used for producing proper scheduling procedures. Our proposed model contains a network calculus-based approach that can calculate the formal service curve of Time-Triggered (TT) and Audio Video Bridge (AVB) for Non-overlapping Gate. For further verification, MATLAB RTC has been utilized for several case studies
