Abstract

The invention discloses a message forwarding method, device and system and a computer readable storage medium, and relates to the field of data communication. The message forwarding method comprises the steps that a service function forwarder SFF obtains an entropy value in an entropy field from a header of a service function chain SFC message, and the entropy value is determined according to transmission information of flow corresponding to the message; the SFF determines a forwarding path of the message according to the entropy; and the SFF forwards the message to the determined forwarding path. According to the embodiment of the invention, messages with the same flow can be forwarded through the same path, and the messages with different flows realize load sharing, so that the dependence on a specific protocol is reduced, and the application range of flow load sharing is improved.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a message forwarding method, device, system and computer-readable storage medium. Background technique [0002] The existing SFC load sharing is realized through the entropy (entropy) label of MPLS. MPLS specially opens up the label value space for the entropy value to select the forwarding path. However, this scheme of using MPLS entropy labels to implement SFC load balancing has the following problems. [0003] (1) The application of entropy labels in MPLS networks (RFC6790) has been abolished by RFC (7447). [0004] (2) This solution is only applicable to the scenario where MPLS is used to carry SFC, and the application range is too small. Contents of the invention [0005] A technical problem to be solved by the embodiments of the present invention is: how to improve the application range of traffic load sharing. [0006] According to a first aspect of some emb...
