The present invention refers to a method for controlling resources on a communication link that transports data in time slots, wherein access to the time slots is distributed among nodes connected to the link. A state of access to a set of one or more of the time slots may be determined by the step of sending an inquiry to one or more of the nodes and receiving one or more replies to the inquiry from the one or more nodes. The inquiry and replies may be related to whether or not any one of the one or more nodes considers itself as currently having access to any one or more of the set of time slots.

Methods for controlling resources in a communication network

The present invention refers to the field of communication networks having a number of nodes connected to the same link, the capacity of the link being divided into frames which in turn are divided into time slots. A procedure is used for informing each node on the link of which nodes that are connected to the link and which slots that it has access to. A verifying procedure is used for subsequently verifying that information separately held by said nodes is not inconsistent regarding the nodes' right to allow sending of data in said slots. In addition, said verifying procedure is disabled from producing a positive verification during transition periods at which different nodes on the link risk having inconsistent link data.
