摘要:
A first component, executing using a processor and a memory in a first data processing system, receives a diagnostic heartbeat packet from a second component executing in a second data processing system, wherein the diagnostic heartbeat packet is a packet comprising a header, a set of heartbeat parameters, and a set of diagnostic attributes. The first component determines, using a value of a diagnostic attribute in the diagnostic heartbeat packet, that a first communication link between the first and the second data processing systems is usable but includes a soft network error, wherein a soft network error condition is a network error condition that adversely affects transmission of packets having certain properties in the data communication network. The first component re-routes a synchronization message from the first component to the second component using a second communication link between the first and the second data processing systems.
