Abstract: A Fault Management (FaM) system monitoring a telecommunication network is able to determine a root cause of a malfunction within the network. The root cause determination is accomplished by receiving alarms from network elements, which may be physical devices, logical interfaces, or a combination thereof. An alarm typically includes a managed object, an alarm name, object type, timestamp, and the like. FaM systems may receive thousands of alarms, where a root cause alarm indicates a malfunction which triggered other alarms to be reported. Alarms are correlated by the FaM system, and a probability is determined for each correlated alarm to be the root cause. The system may have a learning mode, in which it correlates alarms, and an online mode, in which it receives alarms and determines that the alarms are correlated based on data from the learning mode. In some embodiments, both modes may be executed in parallel.

Abstract: In an example, a system includes network nodes implementing an object store. The system may determine reference count updates for objects stored on the object store, and delay persisting the reference count updates to a persistent storage. The system may cancel reference count updates that increments and decrement between the determined reference count update and another reference count update received during the delay in persisting the reference count update to the persistent storage to minimize writing to the object record.

Abstract: In some embodiments, a method receives one or more address resolution mappings and sends the one or more first address resolution mappings to a manager for verification of the one or more first address resolution mappings. The method receives one or more responses based on the verification of the one or more first address resolution mappings and allows or disallows use of the one or more address resolution mappings based on the one or more responses. A list of verified address resolution mappings is received from the manager based on the verification of the one or more first address resolution mappings. Then, the method receives a second address resolution mapping and verifies the second address resolution mapping using the list of verified address resolution mappings.

Abstract: A content delivery network may provide content items to requesting devices using a popularity-based distribution hierarchy. A central analysis system may determine popularity data for a content item stored in a first caching device. At a later time, the central analysis system may determine that a change in the popularity data is beyond a threshold value. The central analysis system may then transmit an instruction to move the content item from the first caching device to a second caching device in a different tier of caching devices than the first caching device. The central analysis system may update a content index to indicate that the content item has been moved to the second caching device. A user device may then be redirected to request the content item directly from the second caching device.

Abstract: Techniques for providing data version comparison between trans-time zone sites. One example method includes target data and a corresponding time stamp is received from each trans-time zone site. Each of the time stamps are based on a respective time zone of a sending trans-time zone site from which the target data and the time stamp were received. Each of the received time stamps are modified based on the respective time zone of the sending trans-time zone site for the time stamp and a time zone of the central server. The received target data is compared from each of the trans-time zone sites to stored target data based on the modified corresponding time stamp. A latest version of the target data is stored by the central server having a modified corresponding time stamp that is greater than each of the other modified corresponding time stamps.

Abstract: Introduced here are computer-implemented techniques for facilitating communication between a central processing system and one or more computing devices. The central processing system can intelligently communicate with at least some of the computing device(s). Moreover, the central processing system can simultaneously or sequentially utilize sensor data generated by multiple computing devices that are known to be associated with one another. For example, if multiple computing devices are known to be in the same general geographical location, then the central processing system may only require that one computing device upload geographical metadata for analysis. If the computing device experiences any issues that prevent the geographical metadata from being uploaded, then the central processing system can automatically prompt another computing device to temporarily or permanently assume the role of leader.
