The present invention relates to a defragmentation method and arrangement for increasement of the average block size of free tokens in the nodes of a DTM (+E,uns D+EE ynamic Synchronous +E,uns T+EE ransfer +E,uns M+EE ode) network. The defragmentation comprises defining a home node for each token at network startup in such way that the tokens sharing the same home node will always define at least partly a continuous slot range, sending back free tokens to home nodes when a significant time has passed and, merging two or more slot-consecutive tokens with the same slot range into a single token when existing in the free pool of a node. The defragmentation can be realized in a central or a distributed token management scheme. |
