Abstract

The invention discloses an SFC-based message forwarding method, device and system, which can realize redirection of a message forwarding path through automatic configuration of a service function forwarding node by a control node. The message forwarding method comprises the following steps that a first service function forwarding node receives a message forwarding rule sent by a control node, wherein the message forwarding rule is used for indicating a mapping relation between a matching item of flow characteristic information of a message and routing prefix information; the first service function forwarding node receives a first message, and a message header of the first message carries traffic feature information of the first message; the first service function forwarding node determines target routing prefix information corresponding to the flow characteristic information of the first message according to the message forwarding rule; and the first service function forwarding node determines target next hop information according to the target routing prefix information, and forwards the first message according to the target next hop information.

Description

[0001] This application is a divisional application of a Chinese patent application submitted to the China Patent Office on May 22, 2017, with the application number 201680003715.X and the title of the invention "Message Forwarding Method, Device and System Based on Service Function Chain SFC". technical field [0002] Embodiments of the present invention relate to the communication field, and more specifically, relate to a message forwarding method, device and system based on a service function chain (SFC). Background technique [0003] Service Function Chaining (SFC for short) is a mechanism for deploying value-added services. In network communication, a group of devices with business processing functions (such as firewall (firewall), Network Address Translation (NAT for short), Deep Packet Inspection (DPI for short), etc.) Combined in an orderly manner, allowing traffic to pass through these service functions constitutes an SFC. The basic architecture of SFC includes con...
