Abstract: An accessory and an electronic device enabling retransmission of data from the electronic device to the accessory when a checksum error occurs in the accessory. An accessory controller of the accessory determines whether or not a checksum received from the camera and a first checksum calculated from data received from the camera match. In a case where the checksums match, the accessory controller calculates a second checksum, whereas in a case where the checksums do not match, the accessory controller calculates a third checksum. The accessory controller transmits the second checksum or the third checksum to the camera according to a result of the determination.

Abstract: Automated methods and systems for identifying and resolving performance problems of objects of a data center are described. The automated methods and systems construct a model for identifying objects of the datacenter that are experiencing performance problems based on baseline distributions of events of the objects in a historical time period and event distributions of events of the objects in a time window located outside the historical time period. A root causes and recommendations database is constructed for resolving performance problems based on remedial measures previously performed for resolving performance problems. The model is used to monitor the objects of data center for runtime performance problems. When a performance problem with an object is detected, the root causes and recommendations database is used to identify a root cause of the performance problem and generate a recommendation for resolving the performance problem in near real time.

The backup application replication layer may provide the session flag to a master application replication layer and to the backup application, and the master application replication layer may provide details of the session to the master application and the backup application.
