The present disclosure generally relates to the field of resource allocation. More specifically, the present disclosure relates to a technique of allocating communication resources in a wireless communication network. The wireless communication network comprises a plurality of access nodes, each of the plurality of access nodes being connected to one or more of the plurality of access nodes via one or more links to provide a plurality of routes for routing data through the wireless communication network. A method embodiment comprises the step of receiving, for one or more links (180, 182) of at least one access node (100) of the plurality of access nodes, allocation information. The allocation information indicates how available communication resources are to be allocated. The method comprises allocating, for the one or more links (180, 182) of the at least one access node (100), the available communication resources based on the received allocation information and a status of one or more data buffers of the at least one access node (100) for buffering data related to one or more of the plurality of routes.
