1. A method for message forwarding, comprising:
- receiving, by a second device in a second domain, a first message from a first domain, wherein the first message carries a first SFPID allocated by the first domain for the first message;
allocating, by the second device for the first message, a second Service Function Path Identifier (SFPID) corresponding to a Service Function Chain (SFC) in the second domain, and obtaining, by the second device, a second message; and
sending, by the second device, the second message to one or more other devices, except the second device, in the second domain;
wherein allocating, by the second device for the first message, the second SFPID corresponding to the SFC in the second domain, and obtaining, by the second device, the second message comprises;
classifying, by the second device, the first message, and generating, by the second device, the second SFPID according to a classification result; and
encapsulating, by the second device, the first message by adding the second SFPID outside the first message, so as to obtain the second message.

Abstract
A method, device and system for message forwarding are provided. The method may include the following acts. A second device in a second domain receives a first message from a first domain. The second device allocates, for the first message, a second Service Function Path Identifier (SFPID) corresponding to a Service Function Chain (SFC) in the second domain, and obtains a second message. The second device sends the second message to one or more other devices, except the second device, in the second domain.

14. A device for message forwarding, which is applied to a second device in a second domain, comprising:
-
a receiving module, which is configured to receive a first message from a first domain, wherein the first message carries a first SFPID allocated by the first domain for the first message; an allocating module, which is configured to allocate, for the first message, a second Service Function Path Identifier (SFPID) corresponding to a Service Function Chain (SFC) in the second domain, and obtain a second message; and a sending module, which is configured to send the second message to one or more other devices, except the second device, in the second domain; wherein the allocating module further comprises; a first classifying unit, which is configured to classify the first message, and obtain a classification result; a first generating unit, which is configured to generate the second SFPID according to the classification result; and an encapsulating unit, which is configured to encapsulate the first message by adding the second SFPID outside the first message, so as to obtain the second message. - View Dependent Claims (15, 16)

17. A system for message forwarding, comprising:
- a first device in a first domain, and a second device in a second domain, wherein,
the second device is configured to receive a first message sent by the first device, wherein the first message carries a first SFPID allocated by the first domain for the first message, allocate, for the first message, a second Service Function Path Identifier (SFPID) corresponding to a Service Function Chain (SFC) in the second domain, obtain a second message, and send the second message to one or more other devices, except the second device, in the second domain; wherein the second device is further configured to classify the first message, and obtain a classification result, generate the second SFPID according to the classification result, and encapsulate the first message by adding the second SFPID outside the first message, so as to obtain the second message.
- a first device in a first domain, and a second device in a second domain, wherein,
