Method for supporting admission control and/or path selection in a communication network and communication network

A method for supporting network admission control or capacity-constrained path selection in a communication network,

• wherein said network includes a plurality of wireless communication links established between a plurality of network nodes,
• wherein said method can accommodate the plurality of wireless communication links being of different link technologies, and wherein said method comprises:
• partitioning in said network said communication links of said network into groups of communication link groups,
• assigning in said network each of said link groups an associated link group controller that is configured to perform at least one of observing and measuring the performance or quality of its associated link group,
• based on said observations or measurements, computing by each link group controller estimates of metrics for a capacity of the associated link group in terms of the capacity of the associated link group and link costs for using each of the communication links of the associated link group, and
• transmitting in said network said estimates to at least one resource management entity that is configured to take network admission control or capacity-constrained path selection decisions on a basis of said estimates,
• wherein said link groups are configured in such a way that communication links in each link group share a capacity of at least one common communication resource, and
• wherein said link groups are configured in such a way that dependency of communication links from different link groups is below a predefined threshold.
