The invention provides a time delay budget route query method, device and system, and the method comprises the steps: obtaining a source end machine room identifier, a host end machine room identifier, a time delay constraint condition and a transmission bandwidth constraint condition, and carrying the source end machine room identifier, the host end machine room identifier, the time delay constraint condition and the transmission bandwidth constraint condition in a time delay budget route query request, sending to a cloud network collaborator, so that the cloud network collaborator respectively inquires and obtains a source end port corresponding to the source end machine room identifier and the transmission bandwidth constraint condition and a sink end port corresponding to the sink end machine room identifier and the transmission bandwidth constraint condition, and sends the source end port and the sink end port to the cloud network collaborator through a national first-level collaborator; obtaining path i
