Performance of a network plays an important role for inter-business communication as well for e-commerce. As the number of machines hooked up on internet increases exponentially resulting in huge amount of data transfer thus requiring a network that is reliable and efficient. With ever-increasing traffic leading to several problems, congestion being one of them.
