A survey on discriminatory processor sharing
The Discriminatory Processor Sharing (DPS) model is a multi-class generalization of the egalitarian Processor Sharing model. In the DPS model all jobs present in the system are served simultaneously at rates controlled by a vector of weights {g(k) > 0; k = 1,..., K}. If there are N-k jobs of class k present in the system, k = 1,..., K, each class-k job is served at rate g(k)/Sigma(K)(j=1) g(j) N-j. The present article provides an overview of the analytical results for the DPS model. In particular, we focus on response times and numbers of jobs in the system.
