Method and equipment for generating forwarding information

Abstract

Disclosed are a method and device for generating forwarding information, the method comprising: receiving a first request packet requesting first content for a first network element; determining, according to obtained first registration information, that a second network element is a provider of the first content; determining a first path from the second network element to the first network element according to a network topology; generating for a first forwarding device the first forwarding information comprising first matching information and first operation information, the first matching information comprising the protocol identifier of the first request packet and the first identifier of the first content, and the first operation information being used to indicate that after determining that the received first data packet matches the first matching information, the first forwarding device encapsulates a first label for the first data packet to obtain a first encapsulated packet; generating for a second forwarding device the second forwarding information comprising second matching information and second operation information, the second operation information being used to indicate that after receiving the first encapsulated packet having the encapsulated first label, the second forwarding device generates for a third forwarding device the third forwarding information comprising second matching information and third operation information, the third operation information being used to indicate that after receiving the first encapsulated packet having the encapsulated first label, the third forwarding device acquires, via de-encapsulation, the first data packet encapsulated in the first encapsulated packet and carrying the first content.

Description

technical field [0001] The present application relates to the communication field, in particular to a method and device for generating forwarding information. Background technique [0002] Information-Centric Network (ICN) is a network technology directly optimized for content delivery. Because the ICN network can route based on the name of the content and use the cache in the network to quickly respond to the content request, it has gained great attention and may replace the traditional Uniform Resource Locator (Uniform Resource Locator, URL) scheme. [0003] At present, the ICN network has been basically completed, and the use of software-defined network technology (Software-Defined Networking, SDN) can well support the ICN network in the existing network architecture. However, because there are many implementation plans for the ICN network, different networks Equipment manufacturers use different implementation schemes, and the ICN network architecture of one implementat...

[0003] At present, the ICN network has been basically completed, and the use of software-defined network technology (Software-Defined Networking, SDN) can well support the ICN network in the existing network architecture. However, because there are many implementation plans for the ICN network, different networks Equipment manufacturers use different implementation schemes, and the ICN network architecture of one implementation scheme cannot be applied to the ICN network architecture of other implementation schemes
