Abstract
This work presents a proven per-hop latency bound
for real-time networks with admission control that does not rely
on shaping or timed gates. It can be applied in a distributed
control plane using only bridge-local information, making it an
ideal candidate for brownfield real-time network installations.
A brief comparison with Asynchronous Traffic Shaping (ATS)
shows that the achieved network utilization is comparable to that
of ATS in some scenarios, while it only lags behind in scenarios
with accumulating bursts where re-shaping could actually reduce
the interference of the observed streams.
