A credit-based shaper (CBS) is adopted to guarantee the timing requirements of stream reservation (SR) class traffic in an Ethernet-audio video bridging (AVB) network, which introduces additional delay for best-effort (BE) traffic. This paper proposes an approach for calculating the worst-case response time (WCRT) of BE traffic and guaranteeing tightness; Moreover, a longest busy interval in which there exits an alternation of pending loads in SR class A and class B traffic at an output port, is defined and identified. Some suggestions for CBS parameters setting can be got form the results.
