Abstract
A credit-based method for controlling data communications in a computer system between a sender and a receiver coupled by an ordered communication link is described herein. A request for a credit check is transmitted from the sender to the receiver via the ordered communication link. An initial number of credits are allocated to the sender in a credit counter. A snapshot counter is set to a value of the credit counter and us updated as returned credits are received. A number of reported credits are determined based on a credit check response message received from the receiver. The returned credits are ordered relative to the credit check response message. The number of credits is checked for consistency based on a number of the snapshot counter and the number of reported credits.
