Abstract: 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.
