Abstract
The growable ATM switch architecture allows a N × N switching fabric to be constructed of output modules that service n outlets by partitioning the output into N/n groups (Fig, 1), Using the generalized knockout principle1 to introduce a known amount of concentrator cell loss these output groups are only required, at most, to accept m cells for any size switch. This allows a growable output queueing switch fabric to be constructed from an N × mN/n expansion network and a series of m × n output modules. The output group operating speed is independent of the switch size.
