An <M D 1 queue> has a <Poisson process> of arrivals, a deterministic service time $\tau$, and one work-conserving server. With arrival rate $\lambda$ and $\lambda\tau<1$, its equilibrium idle probability is $1-\lambda\tau$: the stationary completed work per unit time is $\lambda\tau$. Its output generally need not be a <Poisson process>.
