Stability of join-the-shortest-queue networks

This paper investigates stability behavior in a variant of a generalized Jackson queueing network. In our network, some customers use a join-the-shortest-queue policy when entering the network or moving to the next station. Furthermore, we allow interarrival and service times to have general distributions. For networks with two stations we derive necessary and sufficient conditions for positive...

Large Deviations for Join the Shorter Queue

Large deviations methods and the join-the-shortest-queue model

We develop a methodology for studying “large deviations type” questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are routed to the (weighted) shortest queue. It is not known whether the large deviations principle holds ...

Chasing the dollar: why scientists should decline tobacco industry funding.

ost tobacco researchers now know how the tobacco industry for decades operated clandestinely to obstruct and obfuscate the scientific evidence that smoking causes cancer and, later, that secondhand smoke causes disease in non-smokers. The tobacco industry's internal documents , released as a result of the US states Attorneys General lawsuits and other legal cases, provide ample evidence that is...

5 A large deviation principle for join the shortest queue

We consider a join-the-shortest-queue model which is as follows. There are K single FIFO servers and M arrival processes. The customers from a given arrival process can be served only by servers from a certain subset of all servers. The actual destination is the server with the smallest weighted queue length. The arrival processes are assumed to obey a large deviation principle while the servic...
