This application describes a packet flow out-of-order detection method. After receiving a first packet from a second node, a first node parses the first packet to obtain a flow segment sequence number of the first packet. After receiving the first packet, the first node continues to receive a second packet from the second node, and parses the second packet to obtain a flow segment sequence number of the second packet. The first packet and the second packet belong to a same packet flow. In view of this, the first node may compare the flow segment sequence number of the first packet with the flow segment sequence number of the second packet, to determine whether the packet flow is out of order.

To manage expired backups in a storage system, a backup server retrieves multiple deletion logs which record invalid data included in one or more expired backups. When a deletion condition is met, the backup server identifies a first large object based on the multiple deletion logs, and sends a data migration request to an object-based storage system to instruct the object-based storage system to copy valid data of the first large object to a second large object. Thereafter, the backup server sends an object deletion request to the object-based storage system to instruct the object-based storage system to delete the first large object, thereby clearing up the expired backups.

Method and backup server for processing expired backups

A network device obtains, from a transaction queue, a plurality of transactions that do not conflict with each other, and performs reverse shallow copying in parallel for the transactions that do not conflict, to generate a plurality of temporary trees corresponding to the plurality of transactions. Because the plurality of transactions does not conflict with each other, processing the transactions in parallel can ensure accurate and proper transaction processing. In addition, generating the temporary trees in a reverse shallow copying manner can effectively reduce consumption of time and memory. Further, processing of the plurality of transactions is implemented by merging the plurality of temporary trees.

Parallel copying database transaction processing

A distributed cluster system includes at least a first node, a second node, and a third node, where the first node and the second node have a latest log before a fault occurs, but the third node does not have the latest log before the fault occurs. A fault rectification method includes: setting, by the first node after the first node restarts due to the fault, a voting status of the first node to Voting Not Allowed, where the voting status is used to indicate whether the first node can vote in a process in which the distributed cluster system elects a leader; receiving a replicated-log-entry message from the second node; and setting the voting status of the first node to Voting Allowed, where the second node is a leader.

Fault rectification method, device, and system

Various embodiments provide methods and apparatus for sharing browser contents. In an exemplary method, an electronic device can receive contents for sharing selected by a user and a sharing platform selected by the user. The electronic device can jump to a unified verification interface for the user to log in to the sharing platform through the unified verification interface. Further, the electronic device can submit the contents to the sharing platform for sharing.

Method and apparatus for sharing browser contents

A flow entry delivering method includes: a controller obtains a device identifier of a network device and at least one flow entry used to perform a function on the network device. The controller obtains storage information of the network device according to the device identifier, and the storage information includes free space in storage space of the network device that is used to store a flow entry. The controller compares the free space with a total capacity of the at least one flow entry and determines whether the network device has sufficient free storage space to store the at least one flow entry. When the network device has the storage space greater than or equal to the capacity of the flow entry, the controller delivers the at least one flow entry, or when the network device has no storage space to store the flow entry, the controller does not deliver it.
