Abstract

Todays communication networks are based on modern technologies. In order to attend highest performances the nettwork’s infrastructure is composed mainly on reliable support like optical fiber. The nodes within networks are also based on optical intefaces. Even so due to increased service requirements it must apply some differentiation mechanisms between different service classes. Whether we talk about the Internet network, which has exponentially evolved or about an organization’s network, it is obviosly that quality of service (QoS) assurance is a great challenge for the network’s administrators or communication managers. This paper aims to present in a comparative manner, the mechanisms involved in QoS assurance within network’s elements in the moment that congestion is already present..
