WIPO Patent Application WO/2018/000442
Kind Code:
A1
Abstract:
Disclosed are a method, apparatus and system for forwarding a packet in SFC, capable of standardizing the interaction between a route switching device and a controller, thereby achieving smooth interfacing between the controller and the route switching device. The method comprises: a control node determines routing entry information of a service function forwarding node in a service function path (SFP) in SFC, the routing entry information recording a mapping relationship between routing prefix information and next hop information, the routing prefix information comprising a service path identifier (SPI) and a service index (SI), the SPI being used for identifying the SFP, the SI being used for identifying the position of the service function forwarding node in the SFP, the next hop information being used for indicating a next hop node of the service function forwarding node on the SFP; the control node sends the routing entry information to the service function forwarding node, the routing entry information being used by the service function forwarding node to generate a forwarding table which is used for instructing the service function forwarding node to forward a packet.
