Quality of service control for rt-VBR connections in ATM networks

Nowadays, networks must support applications such as distance learning, electronic commerce, access to the Internet, intranets and extranets, voice over IP (Internet Protocol) and many others. These new applications, employing data, voice, and video traffic, require high bandwidth and quality of service (QoS). The ATM (asynchronous transfer mode) technology, together with dynamic resource allocation methods, offers network connections that guarantee QoS parameters, such as minimum losses and delays. This paper presents a system that uses network management functions together with dynamic resource allocation for provision of end-to-end QoS parameters for rt-VBR (real-time variable bit rate) connections.
