ABSTRACT:
A method and apparatus are disclosed for improving system performance by controlling the flow of transactions between interconnected nodes by considering the system resources required for a transaction response when determining whether to send a transaction. The system uses a debit system for tracking the space consumed by pending transactions between nodes within a particular flow-control class. The system allocates a certain maximum number of debits to a flow-control class. Each time a transaction is sent, a number of debits required to respond to the transaction is computed and added to a debit register. When the debit register reaches the maximum number of debits allocated to it, no more transactions are sent. As transaction responses are completed, the debit register balance is decreased to reflect that more space within the flow-control class for debits is available, such that new transactions might be processed.
