ABSTRACT:
A communications switch comprises a multi-layer switch configuration each layer comprising a synchronized 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-circulation of data from one synchronized packet switch to another synchronized packet switch via paths 35. A number of switch input nodes 32 and output nodes 34 have accesss to each of the synchronized packet switches.
