Abstract: An approach for managing log messages. In this approach, a hierarchical structure identifies primary and secondary relationships between the log messages. In this approach, primary log messages in the log messages that has one or more secondary log messages is identified using the hierarchical structure. One or more pointers are added to each primary log message in the log messages having the one or more secondary log messages. Each pointer points to a secondary log message in the hierarchical structure. The one or more secondary log messages are removed from the log messages to form remaining log messages. Header information from log message headers and content information from log message content in the remaining log messages are saved to form compressed log information.

Abstract: Various systems and methods are presented regarding interrupting a write operation to enable a read operation to be performed on a digital tape system. An initial write operation to the tape can be paused, a read operation performed on a previously written data file conducted, and upon completion of the read operation, the write operation can be recommenced. Interrupt points can be positioned within respective data blocks. Based upon knowledge of the amount of data written during the initial write operation, a position P can be determined (relative to the location of the nearest prior interrupt point) such that when the tape is advanced to place the tape head in a position to recommence the write operation after the read operation has been performed, the tape can be positioned such that the tape head is at position P. Accordingly, interruption of the write operation enables random access of the tape.

Abstract: A dynamic network resource allocation method based on network slicing is provided. A historical resource demand dataset of an accessed network slice is inputted into a first neural network for training. Based on a trained first neural network and the historical resource demand of the accessed network slice, a resource demand prediction information corresponding to the accessed network slice in a first prediction time period is determined. Resources are pre-allocated to the accessed network slice based on the resource demand prediction information, and resources are allocated to the accessed network slice when the first prediction time period arrives. In this way, the service provider can reasonably allocate network resources for network slices without violating the SLA, thus avoiding the waste of network resources.
