Описание: The importance of Quality of Service (QoS) is parallel with the recent evolution of telecom-
munication networks, which are characterized by a great heterogeneity. On the one hand,
many applications require a specific level of assurance from the network. Examples may be assured database access to retrieve information, tele-medicine, remote control of robots in hazardous environments, financial operations, purchase and delivery, tele-learning, applica- tions for emergencies and security. On the other hand, communication networks are charac- terized by many levels of heterogeneity: portions managed by different Service Providers; different transmission means such as cables, satellites and radios; different implemented solutions such as ATM, IPv4, IPv6 and MPLS. Moreover, a network may be heterogeneous also from the point of view of users, who can require different services and have a different availability to pay for them.
