Abstract: Switched Ethernethasenteredinto industrial networking applications more than a decade ago. But the concern of non-determinism about its transmissions is still to be addressed. It is the main issue in industrial applications where the transmissions need to be time-sensitive. AVB (Audio Video Bridging) is one mechanism that can help in improving this determinism. AVB is a set of technical standards used to transport the low-latency streaming services over Ethernet networks. In order to provide low latency, AVB specify the traffic shaping mechanisms that are used to serialize the set of frames. Traffic shaping and transmission selection can be performed by the Credit Based Shaper in AVB. In this paper we analyze the credit based shaper by changing the payload of AVB and observing the impact on best effort traffic. Analysis results indicate that it offers good throughputs at appropriate load conditions.
