    Abstract: 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.

    Abstract: 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.

    Abstract: A path detection method includes a source node that sends a first detection packet including multipath detection indication information and detection data collection indication information, to detect a plurality of paths from the source node to a destination node. A first node directly sends the first detection packet including the multipath detection indication information and the detection data collection indication information to a next-hop node such that the next-hop node of the first node collects detection data in a manner of the first node and no path from the source node to the destination node is missed.

    Abstract: A network performance measurement method includes a first network device that sends a first active measurement protocol packet to a second network device, where the first active measurement protocol packet includes measurement indication information, where the measurement indication information indicates a measurement device on a forward path to measure network performance. The forward path is a forwarding path of the first active measurement protocol packet, and the first network device and the second network device are two ends of the forward path, and the measurement device on the forward path includes at least one intermediate device on the forward path. The intermediate device measures network performance of the forward path
