Multiserver queueing systems are found at the core of a wide variety of practical systems. Many important multiserver models have a previously-unexplained similarity: identical mean response time behavior is empirically observed in the heavy traffic limit. We explain this similarity for the first time. We do so by introducing the work-conserving finite-skip (WCFS) framework, which encompasses a broad class of important models. This class includes the heterogeneousM/G/k, the Limited Processor Sharing policy for theM/G/1, the Threshold Parallelism model and the Multiserver-Job model under a novel scheduling algorithm. We prove that for all WCFS models, scaled mean response timeconverges to the same value,, in the heavy-traffic limit, which is also the heavy traffic limit for theM/G/1/FCFS. Moreover, we prove additively tight bounds on mean response time for the WCFS class, which hold for all load. For each of the four models mentioned above, our bounds are the first known bounds on mean response time.
