Abstract
Disclosed is an arbiter switch for use in forming an asynchronous network of concurrent processors where the arbiter switch receives a message from one of two input ports and transmits it to its output port. A path through the network which has been established can be cleared should it become apparent that particular path has become locked in due to a malfunction of a component in one of the nodes or switches in the network.

An arbitration switch for receiving digital data signals and a clear signal from two different sources in a digital communication network and transmitting those signals to a designation, said switch comprising:
- a pair of input ports one for each of said two different sources to receive said digital data signals and said clear signal from each of said two different sources;
- an arbitration circuit means coupled to said input ports to receive said digital data signals and to select the first set of data signals to be received for subsequent transmission to said destination;
- and
- clear circuit means to receive a clear signal from one of said two different sources by way of one of said input ports, said clear circuit means being coupled to said input ports and to said arbitration circuit means to reset said input ports and said arbitration circuit means.
