Abstract
The present invention relates to a method and an arrangement for centralized and distributed management of capacity (communication resources) in a circuit switched network with shared medium topology (e.g. bus or ring topology), of DTM type (digital synchronous transmission), in which the network use the capacity which are divided into cycles, which in turn are divided into control time slots for signaling and data time slots for data transmission, and where each data time slot is associated with a token. In the centralized version is a first node, named server node, assigned token corresponding to the in one direction sent data time slots on the communication link (e.g., bus or ring). A second node requests token corresponding to a certain capacity from the server node and the server node reserves and transfers tokens corresponding to the capacity requested to the other node in the case the server node has requested capacity unused. In the distributed version the number of server nodes is between two and the total number of nodes connected to the shared medium network.
