  • Patent number: 9439104
    Abstract: A method for supporting admission control and/or path selection in a communication network, the network including a plurality of wireless communication links, possibly of different link technologies, established between a plurality of network nodes, includes the steps of partitioning the communication links of the network into groups of communication links—link groups—, assigning each link group an associated link group controller that is configured to observe and/or measure the performance and/or quality of the link group, based on the observations and/or measurements, computing estimates of metrics for the capacity of the respective link group and the costs for using each of the communication links of the respective link group, and transmitting the estimates to at least one resource management entity being configured to take admission control and/or path selection decisions on the basis of the estimates.

  • Patent number: 9106590
    Abstract: A method for controlling the admission of a flow to a network, particularly a WiMAX (Worldwide Interoperability for Microwave Access) network, wherein an estimation of maximum capacity required within a link of the network and/or within the network will be performed for examining, whether the flow requesting to enter the network with at least one QoS (Quality of Service) reservation of resources can be admitted, by finding first sets of intersections between all pairs of QoS reservations, i.e. the QoS reservations already accepted within the link and/or within the network and the at least one QoS reservation requested by the flow. The method is characterized by structuring the found sets of intersections by building a matrix of intersections of QoS reservations and—based on the matrix—deriving the rest of the sets of intersections between the intersections found, based on information obtained regarding the QoS reservations involved in each intersection.
