Implementation and performance comparison of queuing disciplines for Best-Effort and Time-Sensitive Network

Real-time applications like industrial automation, autonomous vehicles and critical infrastructure systems require deterministic networking strategies to provide efficient data delivery. The networking protocols play an important role in such applications where data transmission of devices is done using TCP/IP based networks. In this study we concentrate on Layer 2 standards of TCP/IP stack to test and validate the scheduling strategies. We examine and compare the performance of legacy scheduling strategies like Round Robin, First In First Out, Token Bucket with Time-sensitive networking standard like IEEE 802.1Qbv. We present the result of all the scheduling strategies and discuss the suitability of these standards for real time and time critical applications. We use Mininet emulator and Linux queuing disciples to validate the standards. The results for delay is discussed for each case.
