Abstract

The invention discloses a path searching method and device which are applied to target electronic equipment. Comprising the steps of obtaining node address information, wherein the node address information comprises a first IP address of a target routing node and a second IP address of a destination node; searching a target routing mask set corresponding to the first IP address in a first data table; determining a target routing mask matched with the node address information from the target routing mask set by using a cuckoo filter; determining a corresponding target routing prefix based on the second IP address and the target routing mask; based on the first IP address, a target routing prefix and a target routing mask, determining node identification of next hop node of target routing node. According to the invention, the next hop node of the target routing node can be found out, and the routing path can be searched.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a path search method and device. Background technique [0002] With the development of computer technology, network routing technology continues to improve. [0003] Currently, in the process of network data transmission in the prior art, an Equal-Cost Multipath Routing (ECMP) routing protocol may be used to transmit data packets from a source node to a destination node. Wherein, there may be multiple routing paths during the transmission of the data packet from the source node to the destination node. When an abnormality occurs during the transmission process, the prior art needs to search all the routing paths to determine the routing path that causes the abnormality. [0004] However, the prior art cannot effectively implement the search for routing paths. Contents of the invention [0005] In view of the above problems, the present invention provides a path search metho...
