In this section we consider a multiserver version of the retrial queue with priority subscribers studied in section 3.2. This is a c-server queueing system in which two different types of primary customers arrive according to independent Poisson flows with rates λ1 and λ2 respectively. Let λ = λl + λ2 be the rate of the joint flow of primary calls. If there is a free server at the time of any primary call arrival, this call begins to be served immediately and leaves the system after service completion.
