I've the following problem to model and program it:
- suppose that we have a central server that provide 3 different services(S1,S2,S3), there is N machine connected to this server: each machine send requests to a server with different rates ( suppose that the arrival rate for each service is a Poisson);
- suppose that for each machine, the rate to request for S1 is: lambda1; the rate to request for S2 is: lambda2; the rate to request for S3 is: lambda3. my question is: how to calculate the global arrival rate of request for this server? is it equal to (lambda1+lambda2+lambda3)/3 ????
Thanks fro every response.
