One telecommunication network is to function as processing traffic that generated by the greater part of customer that connected to network. Customers that to do calling randomly, this mean when started, how long to happen, and when the ended, cannot known exactly. Call generating by costumers and event process on network or switching system got explained as one random process.
A random process or stokastik process is one process where the temporary value from one or more events are varies to time cannot ascertain exactly, but able to predicted with probability. Events in random process known as random variable. Loaded values in random variables from one random process is discretely or continuous.
Telephone traffic qualifying as one stokastik process, where total active customers and total busy server (occupied) simultaneously is random variables. In this telephone traffic case, random variables only load discrete values. Whereas temperature variation value that represented by a random variable result an experiment is sample for continuously value
In reality, it is impossible to estimating accurately total active costumers simultaneously in one moment. What can do is to make a prediction with one probability. Probability theory that generally used for random process approximation is Markov process and Birth-Death Process.
