I've the following problem to model and program it:
- suppose that we have a central server that provides 3 different services($S_1,S_2,S_3$), there are $N$ machines connected to this server: each machine sends requests to the server at different rates (suppose that the arrival rate for each service is a Poisson);
- suppose that for each machine, the request rate for $S_1$ is: $\lambda_1$; the request rate for $S_2$ is: $\lambda_2$; the request rate for $S_3$ is: $\lambda_3$.
my question is: how is the global arrival request rate for this server calculated? is it equal to $(\lambda_1+\lambda_2+\lambda_3)/3$ ????
Thanks for all responses.
