Abstract:
A method for detecting lack of forward progress in a PCI Express includes a step in which a data flow measurement is received or performed. This data flow measurement provides the capacity of the connected Switch or Endpoint device to receive data packets from a Root Complex transmit channel. An error is logged when the data flow measurement does not substantially change in a predetermined period of time. A recovery protocol is executed after logging of the error. A system implementing the method of the invention is also provided.
