SYSTEM AND METHOD FOR PROVIDING DIFFERENTIATED SERVICES

摘要

The present invention relates to a method and arrangements for updating the mapping of trade in the form of a set of service level aggregate flows (SLS1, SLSM) to a set of partial resources (B1, BN) for forwarding the traffic in a communications network (21). Each service level aggregate flow corresponds to a service level associated with a set of service requirements, Information regarding traffic characteristics of each service level aggregate flow and performance of the set of network resources are obtained. Based on this information, the mapping of the set of service level aggregate flows to the set of network resources is updated to achieve a more efficient utilization of the set of network resources, while fulfilling the set of service requirements.
