A communications switch comprises a multi-layer switch configuration each layer comprising a synchronised packet switch with a pre-circulation stage 12, circulation re-entry stage 14, intermediate stage 16, re-circulation exit stage 17 and final exit stage 18. A re-circulation stage 15 allows re-recirculation of data from one synchronised packet switch to another synchronised packet switch via paths 35. A number of switch input nodes 32 and output nodes 34 have access to each of the synchronised packet switches. |
