A telecommunications system employing virtual service network architecture

摘要

The system has a data transport network and a virtual service network (VSN) to provide user data flows with a predetermined quality-of-service (QOS) guarantee across the data transport network. The VSN has a virtual network service controllers (88,90,92) adapted to control the VSN resources and to perform a per-user admission control on each user dataflow that is to be transmitted through the data transport network. An Independent claim is also included for a method to provide a telecommunication system.
