Abstract
A method for deadlock resolution in end-to-end credit protocol includes receiving a data frame and determining a number of credits required to transmit the data frame. The method also includes requesting and receiving credits from an end controller and responsively incrementing a credit counter. The method further includes determining if a value of the credit counter is greater than the number of credits required to transmit the data frame. Based on determining that the value of the credit counter is at least the number of credits required, the method includes transmitting the data frame to the end controller and decreasing the value of the credit counter by the number of credits required to transmit the data frame. Based on determining that the value of the credit counter is less than the number of credits required, the method includes transmitting a credit shortage notification to the end controller.
