METHOD FOR GENERATING FORWARDING INFORMATION, CONTROLLER, AND SERVICE FORWARDING ENTITY

摘要

The present application discloses a method for generating forwarding information. The method includes: determining, by a controller, a first SFE and a second SFE that are used to forward a service stream, where the first SFE and the second SFE are on a service function chain corresponding to the service stream; generating, by the controller, first forwarding information for the first SFE and generating second forwarding information for the second SFE; and sending, by the controller, the first forwarding information to the first SFE and sending the second forwarding information to the second SFE. According to the method for generating forwarding information, the controller generates forwarding information for the SFE, so that a service chaining technology can be applied to a service environment in which a large quantity of services and a large quantity of service processing function units exist.

1. A method for generating forwarding information, comprising:
determining, by a controller, a first service forwarding entity (SFE) and a second SFE that are used to forward a service stream, wherein the first SFE and the second SFE are on a service function chain corresponding to the service stream; generating, by the controller, first forwarding information for the first SFE, wherein the first forwarding information is used to enable the first SFE to forward a first part of the service stream to a first service processing entity (SPE) attached to the first SFE, the first SPE is used to perform service processing on the received first part of the service stream, and the first forwarding information is further used to enable the first SFE to forward a second part of the service stream to the second SFE along the service function chain; generating, by the controller, second forwarding information for the second SFE, wherein the second forwarding information is used to enable the second SFE to forward the second part of the service stream to a second SPE attached to the second SFE, and the second SPE is used to perform service processing on the received second part of the service stream; sending, by the controller, the first forwarding information to the first SFE; and sending, by the controller, the second forwarding information to the second SFE.
