Abstract
The invention relates to a method and device for switching user data, belonging to a connection, between different time slots in a switch or a switch stage such that sequence and frame integrity are preserved. According to the invention, an efficient algorithm is utilized for determining distribution information, in form of storage positions in one or more control memories in the switch. User data is caused to be switched, according to this distribution information from the algorithm, such that these user data maintain the same reciprocal time order through the switch or switch stage. The distribution information determined by the algorithm assures sequence integrity and at the same time minimizes the delay of user data through the switch and/or switch stage. The algorithm also generates control information in form of delay values for delaying some user data such that data belonging to incoming time slots in one and the same frame are assigned to outgoing time slots in the same frame.
