Improving scalability of web applications based on stability of the network with the use of controller PI

This paper presents mathematical model of a computer network and then the model has been presented in the form of a flow chart. RED algorithm is a standard in computer network. RED algorithm has been replaced with the PI controller. In the article it has been assumed that a computer network is a particular dynamic system and it can be examined using known methods of the theory of dynamic systems. We tested of stability for the real computer networks. This method is called method the uncertain parameters space.
