Abstract
A data switching device, such as an ATM or Asynchronous Transfer Mode switch, includes a switching fabric with multiple input and output leads. The device also includes at least one input adapter for receiving data cells on each of a number of input ports and at least one output adapter for delivering data cells switched through the switching fabric to a target port in a set of output ports. Error and format checks are performed on incoming cells and counts are kept of the number of good cells and invalid cells received on a particular input port. To reduce hardware costs, the counts are kept in a random access memory which is shared among the input ports. Several storage locations are allocated to each input port to maintain the necessary counts.
