METHOD AND DEVICE FOR GENERATING FORWARDING INFORMATION
FIG4 is a flowchart of a third network element for requesting a first content from a second network element in a method for generating forwarding information in the present application  FIG5 is a schematic diagram of a structure of an implementation manner of a generating device in the present application
If a third network element also requests the first content in the second network element when the first network element requests the first content in the second network element, then the third network element may request the first content in the second network element by a method as shown in FIG4. The method of this implementation manner is illustrated by taking a generating device as a main body, which includes the following steps.  See FIG5. FIG5 is a schematic diagram of a structure of an implementation manner of a generating device in the present application. The generating device in the implementation manner includes a receiving module 310, a determining module 320, a path generating module 330 and a flow table generating module 340.

['9. A generating device, comprising: a receiving module, configured to receive a first request message used for requesting a first content for a first network element, wherein the first request message comprises a first content identifier; a determining module, configured to determine that a second network element is a provider of the first content according to first registration information sent by the second network element, wherein the first registration information comprises information indicating that the second network element is the provider of the first content; a path generating module, configured to determine a first path from the second network element to the first network element according to a network topology, wherein the first path comprises a first forwarding device; and a flow table generating module, configured to generate first forwarding information for the first forwarding device, wherein the first forwarding information comprising first matching information and first operating information, the first operating information is used for instructing to obtain a first encapsulation message according to a first data message after determining that the first data message matches the first matching information, and send the first encapsulation message to the first network element via the first path.']
