    摘要: A method for performing admission control in order to offer assurances on forwarding quality in networks comprising setting a threshold for each link where the threshold defines a maximum sum of forwarding resources requested by applications for their application data flows, ADFs, on the link. The level of the threshold is chosen by utilising knowledge about multiplexing properties of the ADFs on each link and by utilising knowledge about the forwarding resources of the links.

    摘要: Method and a computer program product for controlling the forwarding quality in a data network including a measurement manager elements for performing end-to-end measurements between nodes in the data network and a Network Resource Manager, NRM, including elements for obtaining information of the network topology. The method includes the steps of: transferring the obtained information of the network routing topology from the NRM to the measurement manager or transferring a result of the performed end-to-end measurements from a measurement manager to the NRM, and combining the end-to-end measurements and the obtained information of the network routing topology into a first information set in order to detect correlated and uncorrelated paths.

    摘要: The present invention relates to a method and arrangements associated with a Bandwidth Manager, BM, adapted to reserve network resources requested from clients for resource objects in a data network. The arrangement comprises means for determining a second amount of resources to be allocated in addition to the required first amount defined by the resource requests from the clients, wherein the second amount of resources to be determined is dependent on the rate at which the first and second amounts of allocated resources can be increased through admitted requests for more resources.

    摘要: A method for controlling the forwarding quality in a data network comprising measuring (S11) end-to-end forwarding quality in measurement nodes (106) located outside the network core and detecting forwarding quality violations in at least one path between these nodes. According to the invention the method comprises the further steps of:—selecting (S13, S15, S17) at least one potentially overloaded interface comprised in the at least one path where quality violations were detected by combining knowledge about different end-to-end measurements performed in the network, with knowledge about the network topology and knowledge about booking levels and forwarding capacity for the interfaces;—defining (S23) a new or adjusting (S21) an already existing provisioning level for each selected interface, such that the usage of each path detected to have forwarding quality violations is limited at one or more interfaces.

    摘要: A method of active queue management, for handling prioritized traffic in a packet transmission system, the method including: providing differentiation between traffic originating from rate adaptive applications that respond to packet loss, wherein traffic is assigned to one of at least two drop precedent levels in-profile and out-profile; preventing starvation of low prioritized traffic; preserving a strict hierarchy among precedence levels; providing absolute differentiation of traffic; and reclassifying a packet of the traffic of the packet transmission system, tagged as in-profile, as out-profile, when a drop probability assigned to the packet is greater than a drop probability calculated from an average queue length for in-profile packets.
