Consider a stable first-come-first-served $GI/GI/s$ queue with $s$ identical servers, i.i.d. interarrival times of finite mean $a$, i.i.d. service times of finite mean $b$, mutuall…

Consider a stable $GI/GI/n$ queue with traffic intensity $\rho$, and seek a universal upper bound on its relevant performance measure that scales as $1/(1-\rho)$. Such a bound is t…

Let $GI/GI/n$ queues be indexed by a sequence approaching heavy traffic, with the number of servers $n$ held fixed. For such a queue, let the traffic intensity be … where $\mu_A$ a…
