Abstract

A system (10) includes a plurality of computers (12) interconnected by a network including one or more switching nodes (11).
The computers (12) transfer messages over virtual circuits established thereamong. The source and destination computers (12) schedule transmission and processing of messages on a round-robin, respectively. Each switching node (11) which forms pan of a path (13) for respective virtual circuits also forwards messages for virtual circuits in a round-robin manner. Round-robin transmission, forwarding and processing at the destination provides a degree of fairness in message transmission.
In addition, messages are also transmitted in one or more cells in a round-robin, so as to reduce delays which may occur for short messages if a long message was transmitted in full for one virtual circuit before beginning transmission of a short message for another virtual circuit. For each virtual circuit, the destination computer (12) and each switching node (11) along the path (13) can generate a virtual circuit flow control message for transmission to the source computer (12) to temporarily limit transmission over the virtual circuit based on the predetermined thresholds, further providing fairness as among the virtual circuits.
Furthermore, each switching node (11) or computer (12) can generate link flow control messages for transmission to neighboring devices (11, 12) in the network (10) to temporarily limit transmission thereto if the amount of resources taken up by all virtual circuits exceeds predetermined thresholds, so as to reduce the likelihood of message loss.
