A network node (10) controls resources (22) in a network. The node (10) includes processing units (12) and assigns, for each set of resources (22), to a unit (12) a master role consisting in reserving and releasing resources (22) and to two processing units (12), named controllers, the role of controlling resources (22). A controller (12c) operates in a first mode when a master role is assigned to a processing unit (12m) and the unit (12m) is available to reserve and release resources (22). A controller (12c) operates in a second mode when no master role is assigned or when a master role is assigned to a unit (12m) which is not available to reserve and release resources (22). In the second mode, a controller (12c) maintains a list (14) of resources (22) to be released and selects a resource (22) from the list (14) to reserve a resource (22). |
