Method for restoring a prescribed sequence for unordered cell streams in ATM switching technology

摘要

In the method a generally unordered cell stream (ICS) is supplied to a generally centrally administered cell memory (CM) and is intermediately stored therein. Path identifier/sequence number signals (VPI/SN) are derived from the cells of the supplied cell stream and are supplied to a resequencing controller (RC) wherein addresses (ADR) for addressing the cell memory (CM) are formed such that an ordered cell stream (OOCS) arises at the output of the cell memory. The method is used in ATM switching technology for switching networks wherein cells of a connection traverse the switching network with different running times.
