METHOD AND DEVICE FOR GENERATING FORWARDING INFORMATION

摘要

The present application discloses a method and device for generating forwarding information. The method includes: receiving a first request message used for requesting a first content for a first network element, determining that a second network element is a provider of the first content according to the obtained first registration information, determining a first path from the second network element to the first network element according to network topology, generating first forwarding information including first matching information and first operating information for the first forwarding device; generating second forwarding information including second matching information and second operating information for the second forwarding device, wherein the second operating information is used for instructing the second forwarding device to receive the first encapsulation message encapsulated with the first label; and generating third forwarding information including the second matching information and third operating information for the third forwarding device, wherein the third operating information is used for instructing the third forwarding device to obtain the first data message encapsulated in the first encapsulation message and carrying the first content by de-encapsulation after receiving the first encapsulation message encapsulated with the first label.
