ABSTRACT:
A credit-based flow control checking scheme is presented for controlling data communications in a closed loop system comprising a sender, a receiver and a link coupling the sender and receiver. The credit-based scheme includes automatically periodically transmitting a credit query from the receiver to the sender and upon return receipt of a credit acknowledge containing the available credit count maintained by the sender, determining whether credit gain or credit loss has occurred subsequent to initialization of the closed loop system. Along with automatically determining whether credit gain or credit loss has occurred, a method/system is presented for automatically correcting the loss or gain without requiring resetting of the closed loop system.
