ABSTRACT:
A connection recovery apparatus for placing a dynamic connection of a dynamic switch of a computer I/O system in a known state upon the detection of a possible switching error. The I/O system includes transmitting stations each having a link-level facility attached by a link to a dynamic-switch port of a dynamic-switch. The dynamic-switch makes dynamic connections between any two of the stations. Upon the detection of a possible switching error, the detecting link-level facility of a station or its attached dynamic-switch port starts a switch recovery procedure which places any dynamic connection to that station in a known disconnected state.
