Abstract

A method and an arrangement for link allocation which provide selecting a free link for a requested connection from a plurality of available route coordinated links according to a particular resource requirement of the requested connection and depending on the current resource seizure of connections that have already been established on utilized links. The establishment of a requested connection and the connections already established have the same or different resource requirement. The current resource seizure for each link resulting from the established connection or connections is stored in a memory. Each link is sorted in the memory in a link allocated memory site which corresponds to the current resource seizure of the link concerned, or the free resource capacity of the link. When a requested connection with a specific resource requirement occurs, it is first evaluated whether or not a link sorted in a selected memory site has residual free capacity for the requirement in question, the memory site being dependent on the specific resource requirement of the connection. When such is the case, establishment of the requested connection is accepted, either via the link or via another suitable link.
