Abstract

The invention discloses a message forwarding method, device and system based on SFC, 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] The present application is submitted to the Chinese Patent Office on May 22, 2017, the application number is 201680003715.x, and the presentation application of the "Message Forwarding Method Based on Business Function Chain SFC Packet Forwarding Method, Application Prutaneous Method, Application Program, Device and System". Technical field [0002] Embodiments of the present invention relate to communication fields, and more particularly to a message forwarding method, apparatus, and system based on a service function chain SFC. Background technique [0003] Service function chaining, referred to as "SFC") is a mechanism for deploying value-added services. In network communication, a set of devices with business processing (such as firewall, network address, referred to as "NAT"), depth packet detection, referred to as "DPI"), etc.) Alternatively, the traffic is integrated into the SFC through these business functions. The basic architecture of the SFC includes control nod...
