Multiserver queueing networks and the tandem queue model (Q1271256)

The paper analyzes the local queueing delay of single server and multiserver queueing networks. Customers only gain access to a downstream queue after completion of the upstream service. Service discipline at all queues is FIFS. To take into account the inference between partial traffic streams, the author considers the concentration tree, over which these traffic streams converge towards local queue. The concept of the apparent overall upstream queueing delay allows him to analyze the distribution of local queue by interpolating between the distribution of the tandem queue and the isolated \(\text{G/G/}s\) queue.
