A process for providing a simulated date and/or time to a time-sensitive application is disclosed herein. Such a process may include detecting the invocation of a time handler method configured to retrieve system time. Upon detecting the invocation, the contents of a call stack may be captured and analyzed to determine which requestor method initiated the invocation. The process may then determine whether the requestor method should receive a real or simulated system time. A real system time may be returned to the requestor method in the event it should receive the real system time. A simulated system time may be returned to the requestor method in the event it should receive the simulated system time. A corresponding apparatus and computer program product are also disclosed and claimed herein.

Date and time simulation for time-sensitive applications

A process for providing a simulated date and/or time to a time-sensitive application is disclosed herein. Such a process may include detecting the invocation of a time handler method configured to retrieve system time. Upon detecting the invocation, the contents of a call stack may be captured and analyzed to determine which requester method initiated the invocation. The process may then determine whether the requester method should receive a real or simulated system time. A real system time may be returned to the requester method in the event it should receive the real system time. A simulated system time may be returned to the requester method in the event it should receive the simulated system time. A corresponding apparatus and computer program product are also disclosed and claimed herein.

A method for detecting and managing a futile neighbor state loop during link state routing is disclosed. The method can include reading a threshold parameter for link state routing, wherein the threshold parameter indicates a number of routing attempts, and performing link state routing to a node via a primary interface. The method can further include detecting a futile neighbor state loop during link state routing to the node via the primary interface by detecting a number of routing attempts that has reached the threshold parameter and detecting an available backup interface to the node. The method can further include suspending the primary interface to the node and switching routing to the backup interface.
