Simulating and Emulating the Characteristic Packet Delay of Logical 5G TSN Bridges

Abstract

Due to the demand of many time-sensitive mobile applications, there is currently a strong trend to extend Time- Sensitive Networking (TSN) to the wireless domain. In particular, 3GPP has speficied a logial 5G TSN bridge, which implements the same functions as wireline TSN bridges (e.g. the Time- Aware Shaper of IEEE 802.1Qbv). However, a logical bridge has fundamentally different port-to-port delay properties than its wired counterpart. In this paper, we present two open-source tools and open latency data sets for simulating and emulating the characteristic port-to-port delay of logical 5G TSN bridges.
