The IP QoS System

This paper shortly describes the IP QoS System which offers strict quality of service (QoS) guarantees in IPbased networks and supports a number of, so called, classes of services. Such solution requires to implement in the network a set of QoS mechanisms and algorithm working on packet, connection request and provisioning levels. Furthermore, we require signaling system for informing the network about new connection request and network resource allocation capabilities for providing required resources to given connection. The IP QoS System is based on the next generation networks (NGN) and differentiated services (DiffServ) architectures and, at least for now, it is designed for single domain only. Keywords—classes of service, DiffServ, multi-service networks, NGN, quality of service.
