Independent WCRT analysis for the Best-Effort class BE in Ethernet AVB

Existing papers on worst-case response time analysis for individual classes in Ethernet AVB typically focus on classes under credit-based shaping (CBS). There also exist industrial applications that use the Best-Effort class BE for non-hard real-time traffic with a minimum quality-of-service (QoS) require-ment, however. In this paper, we therefore present a conjecture for worst-case response time analysis for that class BE, stating that the existing analysis based on eligible intervals can be equally well applied to a single (highest-priority) stream without CBS, by simply assuming the remaining bandwidth to be available to that stream. The conjecture is illustrated using a figure.
