M/M/c queue model for the distributed server.This is a graphical representation of a M/M/c queue model, with c parallel servers (c>1), each serving user requests. All requests reaching the system join a single queue, and they are served in their order of arrival. λ is the arrival rate, i.e., the average number of requests that reach the system per time unit, modeled as a Poisson distribution. μ is the service rate, i.e., the average number of requests that a server can process per time unit
