Denial of service attack mitigation based on compute node failures is described herein. In an example, a system can include a first point of presence (POP) that is located in a first region and a server that is located in a second region. The system can also include a first compute node that is located in the first region and communicatively coupled with the first POP or that is located in the second region and communicatively coupled with the server and has a smaller capacity to handle requests than each of the POP and the server. The first compute node is configured to receive a request of the POP indicating a network address of the server, determine data to send the request along a network path to the server, and send the request along the network path based on the data.

In some examples, a system groups a multitude of blocks of coded data into first segments, where each first segment comprises several blocks from the multitude of blocks, and the coded data is based on the application of a deletion correction coding to input data. The system stores the first segments in corresponding error domains of a first set of error domains in a first deletion correction configuration, where the first deletion correction configuration allows error recovery in response to lost coded data in a specified number of error domains. The system transitions from the first deletion correction configuration to a second deletion correction configuration by reorganizing the first segments into second segments, where each second segment comprises a different number of blocks of coded data than a first segment.

The application provides a self-adaptive solid state disk power failure protection method and device. The method comprises the following steps: after triggering power failure, firstly, the physical address of the data to be persisted in the volatile cache is directly determined by calculation based on a pre-stored linear mapping relationship, so as to eliminate the energy consumption and delay of traditional traversal search; secondly, the real-time available energy of the energy storage array is obtained and compared with a preset energy demand threshold; the energy demand threshold is obtained based on load prediction; if the energy is insufficient, part of the data subset is abandoned to be written according to the dynamically generated data priority order; finally, the selected data subset is written into the non-volatile storage medium according to the calculated physical address. The application significantly improves the power failure protection success rate and system energy efficiency.

A procedure implemented on a computer includes receiving a request to increase the size of a backup storage space for a storage medium; adding additional storage areas to the backup storage space in response to the request; identifying an existing storage area within the backup storage space; determining whether there are any occupied storage areas between the existing storage area and the additional storage areas added to the backup storage space; and conditionally using the additional storage areas added to the backup storage space based on this determination.

The application relates to a memory object reference analysis method and device, computer equipment, a storage medium and a computer program product. After a memory object query request is acquired, memory object address information is searched. According to the memory object address information, a socket connection mode is used to access a memory monitoring object. Memory object serialization information fed back by the memory monitoring object is acquired. The memory object serialization information is deserialized to acquire memory object reference information corresponding to the memory object query request. Memory object reference analysis information is generated according to the memory object reference information. The memory object reference analysis method can acquire memory object serialization information from the memory monitoring object through the socket connection, thereby obtaining corresponding memory object reference relationships through deserialization, realizing memory object reference relationship identification and display in a running process of the memory monitoring object, and performing more in-depth memory object reference analysis.

A memory apparatus and a method for operating the same. The method includes performing a read operation on a set of memory cells, detecting an error in data read from the set of memory cells based on an error correction code (ECC) operation performed on the data, and performing a scrubbing operation or a refreshing operation on the set of memory cells according to a detecting result.

The application provides a memory data protection method and a terminal. Target data in original memory pointed by a target process in a base address register is copied; a new copy memory is created in the base address register, the target data is written into the copy memory, and the target data in the original memory is deleted; and access exception is set for the original memory. In the base address register, the target data in the original memory has been transferred, and in the base address register, the target process only points to the original memory and does not point to the copy memory, so that the position of the copy memory cannot be acquired by the outside, thereby realizing protection of the data, and for the inside, the target data required can be continuously acquired through the copy memory, so that the normal memory access process required is not affected; thus, defense against static analysis and dynamic analysis is realized, and the data in the memory is prevented from being acquired by the outside.
