Abstract
A multi-nodal data processing system includes a plurality of processing nodes, each node connected to plural other nodes by bidirectional data links. Each node comprises receivers for receiving messages on bidirectional data links and transmitters for transmitting messages on bidirectional data links. Each node records child nodes to which a message was transmitted and is further adapted to transmit a lock-up message received from a child node to a parent node, the lock-up message indicating a successful establishment of a message signal path to a destination node. Each node further is adapted to transmit a link cancel signal to another node to close the link in the event of an unsuccessful message transfer attempt over the link. Each node inhibits transmission of a lock-up signal to a parent node until link cancel signals have been received from all child nodes (other than a node from which a lock-up signal was received). A source node (where a message originates) continues transmission of its message, even before a lock-up signal has been received. The destination node which originates the lock-up message terminates a bidirectional data link by an end-of-session signal when it ha…
