Behavior injection uses non-volatile memory to preserve persistence of filter context information across possible system errors, for reporting of the results of behavior injection, and to preserve information across recovery from system errors. Multiple behavior injection threads are also provided.

Abstract: Complex on-chip interconnect fabrics, particularly those that include point-to-point interconnects and coherent routing networks, can present significant challenges for conventional trace techniques that may be applied in an effort to efficiently provide an external debugger with visibility into on-chip interconnect transactions.

These separate message instances embed appropriate tag and mark values to allow the message instances to be post-processed and correlated by the external debug tools so as to reconstruct the transaction information for operations performed in the on-chip interconnect.

Abstract: The present invention relates to a failure detection method and system operating at the session control layer, preferably within an IMS/SIP architecture, which monitors the status of an adjacent node with the aid of a timer mechanism that sets a heartbeat rate associated with that adjacent node. Monitoring of a communication session takes place by monitoring the liveliness of the nodes handling the session. According to some embodiments, SIP traffic within an on-going communication session is used to determine whether an adjacent node is alive. Failure to receive a SIP message from an adjacent node within a given heartbeat rate starts a polling process to decide whether the adjacent node is in a faulty status. In the affirmative, i.e. upon decision that the adjacent node is in a faulty status, the polling node closes the communication session so that any further billing is prevented.

Abstract: A stale of a managed client device in a distributed autonomic computing environment is attached to an event occurring on the managed client device. The event is sent, with the attached state of the managed client device, to a server. The state of the managed client device is saved at the server.

An execution condition is dynamically generated based on the saved state of the managed client device. The execution condition is added to the action to be executed and sent to the managed client device. At the managed client device, a determination is made whether to execute the action based on the execution condition and a current state of the managed client device.

Finally, the reception of a precondition for triggering defined by the arm condition is limited to those ports that have received the arm condition.
