ABSTRACT
Internet Protocol-based applications are the prevailing trend of the telecommunications market, but the path towards the "IP over everything" target is not unhampered. The main shortcoming of the IP protocol is its incapability of providing guaranteed Quality of Service (QoS), although significant effort is spent within different standardization bodies and organizations. We propose architecture for the implicit and explicit service activation of Internet Services with guaranteed QoS, based on existing Service Level Specification (SLS). The supported level of QoS is according to the customer's demands and the network supportability defined within the terms of a signed Service Level Agreement (SLA). The main idea is that the service provider can perform service management effectively in an aggregated manner while the customer is provided with an uncomplicated interface to specify his service request.
