A growable ATM switch using an optical bus as the interconnection network

Summary form only given. The growable ATM switch architecture allows a N x N switching fabric to be constructed of output modules that service n outlets by partitioning the output into N/n groups. Using the generalized knockout principle 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 X mN/n expansion network and a series of m x n output modules.
