Method and device for troubleshooting fronthaul network

The invention provides a method and a device for troubleshooting a fronthaul network. The method and the device are used for solving the technical problem of low communication efficiency caused by relatively long troubleshooting time. The scheme for troubleshooting the forward transmission network comprises the following steps: storing a data packet sent by a baseband processing unit to a forward transmission cache region; determining a starting time node, an ending time node and a time pulse window constructed by the starting time node and the ending time node according to the time pulse; when the residual capacity of the current transmission cache region is not allowed to store the data packet, taking the storage time of the data packet as the maximum advance, and determining a starting time node of the time window; obtaining a preset data flow parameter, determining the time of at least storing the data packet in the forward cache region as the minimum lead, and constructing a time window; and the radio re
